13 Mechanical Description
The SYNCROTRAK 983214 flow prover consists of a smooth bore flow tube with a free
moving piston with bubble tight radial seals and an internal poppet valve A continuous
shaft exits both ends of the flow tube causing the prover to displace equal volumes both
upstream and downstream of the piston Volume detection switches are field replaceable
Volume detectors are actuated by a flag which is attached to the piston return shaft The piston is returned to the upstream position by a mechanical drive driven by an explosion-
proof electric motor The return mechanism is completely unlatched from the pistonassembly during a proving run allowing the piston to follow the flowing stream with
complete freedom for the least effect upon the flowing stream
14 Tests and Certifications
The SYNCROTRAK 983214 Flow Prover has been factory calibrated (water drawn) using NIST traceable test equipment The water draw was performed by the gravimetric
method using the CALIBRON dual-valve water draw valve set in conjunction with anelectronic balance Base volume on the certificate of calibration is corrected to 0 psig and
60 degF (or to meet other customer requirements) Before using the SYNCROTRAK 983214
FlowProver be certain that the setup information is correct concerning the input of the volume
corresponding to the certification sheet for the prover
Calibron Systems Inc recommends volumetric re-certification to be performed by the
user at regular intervals Frequency of recertification is determined by the frequency ofusage or by other user convention The optical switches on the prover switchbar may be
replaced without volume recertification however Calibron Systems recommends that a
check draw be performed to verify the volume after switch replacement Refer to the
water draw procedure described in Section 3 for more details

15 Principle of Operation
In the stand-by mode the piston is down stream and stationary The pistonrsquos inner flow-thru valve is open (ie
slightly up-stream of the main piston body) allowing free flow of the fluid through the flow proverrsquosmeasurement cylinder with insignificant pressure loss
When the operator starts a proving run sequence (Fig 11) the computer then signals the explosion-proofmotor to pull the piston to the up-stream position The piston is then completely unlatched from the chain
drive return mechanism The low drag piston traveling down the smooth bore tube is now free to follow thefluid flow with the least possible effect on the flow stream When the piston is released the flow-thru valvecloses by spring tension (Fig 12) The piston velocity is now synchronized with the fluid velocity
After the piston has been released and after a short run-up the precision optical start of volume switch is
actuated sending a signal to the proving computer starting the timing sequence The piston continuesdownstream with the flow Upon reaching the end of volume switch a signal is sent to the provingcomputer stopping the timing sequence Just after passing the end of volume switch the piston shaft is
stopped mechanically The flow through the prover pushes the perimiter of the piston further downstreamopening the flow-thru valve and allowing the flow to continue with little to no pulse or surge in line
pressure
To begin the next proving run sequence a signal is sent from the proving computer activating the return
mechanism pulling the piston to the upstream position where it is released to obtain another data point

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1541
15
9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

4 Remove downstream shaft cover by removing outer support carefully sliding tube
cover from the shaft and unscrew the threaded rod from the downstream seal retainer(53101 fig 66)
5 Remove the 4 bolts (item 53107 fig 66) holding the stop and seal retainer to the endflange and remove the stop (Fig 66 item 53101) as shown in Fig 61
6 Remove the bracket securing the flow tube and downstream flange to the frame
7 Remove the hex socket bolts (item 53003) securing the downstream end flange 53001
to the flow tube except for 1 bolt at the top Connect a hoist to the threaded hole in thetop of the downstream flange (fig 62) Remove the last hex socket bolt and using thehoist to support the flange remove it from the flow tube

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

13 Mechanical Description
The SYNCROTRAK 983214 flow prover consists of a smooth bore flow tube with a free
moving piston with bubble tight radial seals and an internal poppet valve A continuous
shaft exits both ends of the flow tube causing the prover to displace equal volumes both
upstream and downstream of the piston Volume detection switches are field replaceable
Volume detectors are actuated by a flag which is attached to the piston return shaft The piston is returned to the upstream position by a mechanical drive driven by an explosion-
proof electric motor The return mechanism is completely unlatched from the pistonassembly during a proving run allowing the piston to follow the flowing stream with
complete freedom for the least effect upon the flowing stream
14 Tests and Certifications
The SYNCROTRAK 983214 Flow Prover has been factory calibrated (water drawn) using NIST traceable test equipment The water draw was performed by the gravimetric
method using the CALIBRON dual-valve water draw valve set in conjunction with anelectronic balance Base volume on the certificate of calibration is corrected to 0 psig and
60 degF (or to meet other customer requirements) Before using the SYNCROTRAK 983214
FlowProver be certain that the setup information is correct concerning the input of the volume
corresponding to the certification sheet for the prover
Calibron Systems Inc recommends volumetric re-certification to be performed by the
user at regular intervals Frequency of recertification is determined by the frequency ofusage or by other user convention The optical switches on the prover switchbar may be
replaced without volume recertification however Calibron Systems recommends that a
check draw be performed to verify the volume after switch replacement Refer to the
water draw procedure described in Section 3 for more details

15 Principle of Operation
In the stand-by mode the piston is down stream and stationary The pistonrsquos inner flow-thru valve is open (ie
slightly up-stream of the main piston body) allowing free flow of the fluid through the flow proverrsquosmeasurement cylinder with insignificant pressure loss
When the operator starts a proving run sequence (Fig 11) the computer then signals the explosion-proofmotor to pull the piston to the up-stream position The piston is then completely unlatched from the chain
drive return mechanism The low drag piston traveling down the smooth bore tube is now free to follow thefluid flow with the least possible effect on the flow stream When the piston is released the flow-thru valvecloses by spring tension (Fig 12) The piston velocity is now synchronized with the fluid velocity
After the piston has been released and after a short run-up the precision optical start of volume switch is
actuated sending a signal to the proving computer starting the timing sequence The piston continuesdownstream with the flow Upon reaching the end of volume switch a signal is sent to the provingcomputer stopping the timing sequence Just after passing the end of volume switch the piston shaft is
stopped mechanically The flow through the prover pushes the perimiter of the piston further downstreamopening the flow-thru valve and allowing the flow to continue with little to no pulse or surge in line
pressure
To begin the next proving run sequence a signal is sent from the proving computer activating the return
mechanism pulling the piston to the upstream position where it is released to obtain another data point

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1541

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

13 Mechanical Description
The SYNCROTRAK 983214 flow prover consists of a smooth bore flow tube with a free
moving piston with bubble tight radial seals and an internal poppet valve A continuous
shaft exits both ends of the flow tube causing the prover to displace equal volumes both
upstream and downstream of the piston Volume detection switches are field replaceable
Volume detectors are actuated by a flag which is attached to the piston return shaft The piston is returned to the upstream position by a mechanical drive driven by an explosion-
proof electric motor The return mechanism is completely unlatched from the pistonassembly during a proving run allowing the piston to follow the flowing stream with
complete freedom for the least effect upon the flowing stream
14 Tests and Certifications
The SYNCROTRAK 983214 Flow Prover has been factory calibrated (water drawn) using NIST traceable test equipment The water draw was performed by the gravimetric
method using the CALIBRON dual-valve water draw valve set in conjunction with anelectronic balance Base volume on the certificate of calibration is corrected to 0 psig and
60 degF (or to meet other customer requirements) Before using the SYNCROTRAK 983214
FlowProver be certain that the setup information is correct concerning the input of the volume
corresponding to the certification sheet for the prover
Calibron Systems Inc recommends volumetric re-certification to be performed by the
user at regular intervals Frequency of recertification is determined by the frequency ofusage or by other user convention The optical switches on the prover switchbar may be
replaced without volume recertification however Calibron Systems recommends that a
check draw be performed to verify the volume after switch replacement Refer to the
water draw procedure described in Section 3 for more details

15 Principle of Operation
In the stand-by mode the piston is down stream and stationary The pistonrsquos inner flow-thru valve is open (ie
slightly up-stream of the main piston body) allowing free flow of the fluid through the flow proverrsquosmeasurement cylinder with insignificant pressure loss
When the operator starts a proving run sequence (Fig 11) the computer then signals the explosion-proofmotor to pull the piston to the up-stream position The piston is then completely unlatched from the chain
drive return mechanism The low drag piston traveling down the smooth bore tube is now free to follow thefluid flow with the least possible effect on the flow stream When the piston is released the flow-thru valvecloses by spring tension (Fig 12) The piston velocity is now synchronized with the fluid velocity
After the piston has been released and after a short run-up the precision optical start of volume switch is
actuated sending a signal to the proving computer starting the timing sequence The piston continuesdownstream with the flow Upon reaching the end of volume switch a signal is sent to the provingcomputer stopping the timing sequence Just after passing the end of volume switch the piston shaft is
stopped mechanically The flow through the prover pushes the perimiter of the piston further downstreamopening the flow-thru valve and allowing the flow to continue with little to no pulse or surge in line
pressure
To begin the next proving run sequence a signal is sent from the proving computer activating the return
mechanism pulling the piston to the upstream position where it is released to obtain another data point

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1941
19
9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

13 Mechanical Description
The SYNCROTRAK 983214 flow prover consists of a smooth bore flow tube with a free
moving piston with bubble tight radial seals and an internal poppet valve A continuous
shaft exits both ends of the flow tube causing the prover to displace equal volumes both
upstream and downstream of the piston Volume detection switches are field replaceable
Volume detectors are actuated by a flag which is attached to the piston return shaft The piston is returned to the upstream position by a mechanical drive driven by an explosion-
proof electric motor The return mechanism is completely unlatched from the pistonassembly during a proving run allowing the piston to follow the flowing stream with
complete freedom for the least effect upon the flowing stream
14 Tests and Certifications
The SYNCROTRAK 983214 Flow Prover has been factory calibrated (water drawn) using NIST traceable test equipment The water draw was performed by the gravimetric
method using the CALIBRON dual-valve water draw valve set in conjunction with anelectronic balance Base volume on the certificate of calibration is corrected to 0 psig and
60 degF (or to meet other customer requirements) Before using the SYNCROTRAK 983214
FlowProver be certain that the setup information is correct concerning the input of the volume
corresponding to the certification sheet for the prover
Calibron Systems Inc recommends volumetric re-certification to be performed by the
user at regular intervals Frequency of recertification is determined by the frequency ofusage or by other user convention The optical switches on the prover switchbar may be
replaced without volume recertification however Calibron Systems recommends that a
check draw be performed to verify the volume after switch replacement Refer to the
water draw procedure described in Section 3 for more details

15 Principle of Operation
In the stand-by mode the piston is down stream and stationary The pistonrsquos inner flow-thru valve is open (ie
slightly up-stream of the main piston body) allowing free flow of the fluid through the flow proverrsquosmeasurement cylinder with insignificant pressure loss
When the operator starts a proving run sequence (Fig 11) the computer then signals the explosion-proofmotor to pull the piston to the up-stream position The piston is then completely unlatched from the chain
drive return mechanism The low drag piston traveling down the smooth bore tube is now free to follow thefluid flow with the least possible effect on the flow stream When the piston is released the flow-thru valvecloses by spring tension (Fig 12) The piston velocity is now synchronized with the fluid velocity
After the piston has been released and after a short run-up the precision optical start of volume switch is
actuated sending a signal to the proving computer starting the timing sequence The piston continuesdownstream with the flow Upon reaching the end of volume switch a signal is sent to the provingcomputer stopping the timing sequence Just after passing the end of volume switch the piston shaft is
stopped mechanically The flow through the prover pushes the perimiter of the piston further downstreamopening the flow-thru valve and allowing the flow to continue with little to no pulse or surge in line
pressure
To begin the next proving run sequence a signal is sent from the proving computer activating the return
mechanism pulling the piston to the upstream position where it is released to obtain another data point

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1541

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

13 Mechanical Description
The SYNCROTRAK 983214 flow prover consists of a smooth bore flow tube with a free
moving piston with bubble tight radial seals and an internal poppet valve A continuous
shaft exits both ends of the flow tube causing the prover to displace equal volumes both
upstream and downstream of the piston Volume detection switches are field replaceable
Volume detectors are actuated by a flag which is attached to the piston return shaft The piston is returned to the upstream position by a mechanical drive driven by an explosion-
proof electric motor The return mechanism is completely unlatched from the pistonassembly during a proving run allowing the piston to follow the flowing stream with
complete freedom for the least effect upon the flowing stream
14 Tests and Certifications
The SYNCROTRAK 983214 Flow Prover has been factory calibrated (water drawn) using NIST traceable test equipment The water draw was performed by the gravimetric
method using the CALIBRON dual-valve water draw valve set in conjunction with anelectronic balance Base volume on the certificate of calibration is corrected to 0 psig and
60 degF (or to meet other customer requirements) Before using the SYNCROTRAK 983214
FlowProver be certain that the setup information is correct concerning the input of the volume
corresponding to the certification sheet for the prover
Calibron Systems Inc recommends volumetric re-certification to be performed by the
user at regular intervals Frequency of recertification is determined by the frequency ofusage or by other user convention The optical switches on the prover switchbar may be
replaced without volume recertification however Calibron Systems recommends that a
check draw be performed to verify the volume after switch replacement Refer to the
water draw procedure described in Section 3 for more details

15 Principle of Operation
In the stand-by mode the piston is down stream and stationary The pistonrsquos inner flow-thru valve is open (ie
slightly up-stream of the main piston body) allowing free flow of the fluid through the flow proverrsquosmeasurement cylinder with insignificant pressure loss
When the operator starts a proving run sequence (Fig 11) the computer then signals the explosion-proofmotor to pull the piston to the up-stream position The piston is then completely unlatched from the chain
drive return mechanism The low drag piston traveling down the smooth bore tube is now free to follow thefluid flow with the least possible effect on the flow stream When the piston is released the flow-thru valvecloses by spring tension (Fig 12) The piston velocity is now synchronized with the fluid velocity
After the piston has been released and after a short run-up the precision optical start of volume switch is
actuated sending a signal to the proving computer starting the timing sequence The piston continuesdownstream with the flow Upon reaching the end of volume switch a signal is sent to the provingcomputer stopping the timing sequence Just after passing the end of volume switch the piston shaft is
stopped mechanically The flow through the prover pushes the perimiter of the piston further downstreamopening the flow-thru valve and allowing the flow to continue with little to no pulse or surge in line
pressure
To begin the next proving run sequence a signal is sent from the proving computer activating the return
mechanism pulling the piston to the upstream position where it is released to obtain another data point

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

15 Principle of Operation
In the stand-by mode the piston is down stream and stationary The pistonrsquos inner flow-thru valve is open (ie
slightly up-stream of the main piston body) allowing free flow of the fluid through the flow proverrsquosmeasurement cylinder with insignificant pressure loss
When the operator starts a proving run sequence (Fig 11) the computer then signals the explosion-proofmotor to pull the piston to the up-stream position The piston is then completely unlatched from the chain
drive return mechanism The low drag piston traveling down the smooth bore tube is now free to follow thefluid flow with the least possible effect on the flow stream When the piston is released the flow-thru valvecloses by spring tension (Fig 12) The piston velocity is now synchronized with the fluid velocity
After the piston has been released and after a short run-up the precision optical start of volume switch is
actuated sending a signal to the proving computer starting the timing sequence The piston continuesdownstream with the flow Upon reaching the end of volume switch a signal is sent to the provingcomputer stopping the timing sequence Just after passing the end of volume switch the piston shaft is
stopped mechanically The flow through the prover pushes the perimiter of the piston further downstreamopening the flow-thru valve and allowing the flow to continue with little to no pulse or surge in line
pressure
To begin the next proving run sequence a signal is sent from the proving computer activating the return
mechanism pulling the piston to the upstream position where it is released to obtain another data point

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by
SYNCROTRAK reg Operation Manual

figures 61 through 68 and the parts list supplied with your prover
1 Disconnect power from prover stand
2 Disconnect prover from line or block off from line and drain completely
3 Disassemble prover drive hood by removing the 14 20 X 1 hex head bolts starting
with the side panels then the top panel outer end panel and inner panel
Fig 61 Fig 62
4 Remove downstream shaft cover by removing outer support carefully sliding tube
cover from the shaft and unscrew the threaded rod from the downstream seal retainer(53101 fig 66)
5 Remove the 4 bolts (item 53107 fig 66) holding the stop and seal retainer to the endflange and remove the stop (Fig 66 item 53101) as shown in Fig 61
6 Remove the bracket securing the flow tube and downstream flange to the frame
7 Remove the hex socket bolts (item 53003) securing the downstream end flange 53001
to the flow tube except for 1 bolt at the top Connect a hoist to the threaded hole in thetop of the downstream flange (fig 62) Remove the last hex socket bolt and using thehoist to support the flange remove it from the flow tube
8 Remove the hex cap screw (1) fig 63) holding the guide plate (2) to the upstreamshaft

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure

321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141
11
321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

3 CALIBRATION
31 General
It is recommended that prior to doing any volumetric calibration especially if the prover
is to be used in the USA for custody transfer meter proving that the personnel involvedread the API Manual of Petroleum Measurement Standards (MPMS) Chapter 4 - Proving
Systems sec 48 and the MPMS Chapters 4371 1123 1221 and 1224 - pertaining
to the calculation for the volume of provers
Although the prover may be calibrated with calibrations traceable to the US National
Bureau of Standards by a number of techniques only two techniques for volume
determination will be described here a volumetric calibration and a gravimetric or mass
calibration
The mass or gravimetric calibration method consists of collecting the volume of water
dispensed by the prover between volume switches and determining its mass by weighing
it with precision scales or a balance Corrections are made for the density of the waterand the buoyancy of the air displaced by the volume of water per API 146 and applying
various other correction factors such as the temperature and pressure effects on the flow
tube and the volume switch position De-ionized or distilled water should be utilized forthe mass draws API 11235 Wagenbreth equation is the API standard used for density
determination of water
The displaced volume has been calibrated as described in the MPMS chapters 4371
1123 1221 1224 491 492 and 494
The SYNCROTRAK 983214 prover base volume has been determined at the factory
Recalibration is recommended either at 1-year intervals or at intervals as agreed upon by
the authorities and parties interested in the measurement Recalibration is also requiredafter any maintenance which may affect the base volume eg complete switchbar
replacement SYNCROTRAK 983214 volume switches are field replaceable and adjusted to anextremely high degree of precision Individual switch replacement does not necessitate
volumetric re-calibration
32 Static Leak Detection
The SYNCROTRAK 983214
static leak detection procedure should be utilized prior to waterdraw or at any time that meter proof repeatability is difficult to attain and the prover not
the meter is suspected It is not necessary to remove the prover from the process line to
perform a leak test It is only necessary to block off the inlet and outlet of the prover withit full of fluid It is also necessary to have a differential pressure gauge with a sufficient pressure rating to withstand line pressure if the prover is not removed from the process
line Temperatures both ambient and fluid should be stable during the procedure
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1141
11
321Equipment
1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214
5 From the proving computer initiate a proving run6 Remove the plug from the drive cover end panel
7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by
SYNCROTRAK reg Operation Manual

figures 61 through 68 and the parts list supplied with your prover
1 Disconnect power from prover stand
2 Disconnect prover from line or block off from line and drain completely
3 Disassemble prover drive hood by removing the 14 20 X 1 hex head bolts starting
with the side panels then the top panel outer end panel and inner panel
Fig 61 Fig 62
4 Remove downstream shaft cover by removing outer support carefully sliding tube
cover from the shaft and unscrew the threaded rod from the downstream seal retainer(53101 fig 66)
5 Remove the 4 bolts (item 53107 fig 66) holding the stop and seal retainer to the endflange and remove the stop (Fig 66 item 53101) as shown in Fig 61
6 Remove the bracket securing the flow tube and downstream flange to the frame
7 Remove the hex socket bolts (item 53003) securing the downstream end flange 53001
to the flow tube except for 1 bolt at the top Connect a hoist to the threaded hole in thetop of the downstream flange (fig 62) Remove the last hex socket bolt and using thehoist to support the flange remove it from the flow tube
8 Remove the hex cap screw (1) fig 63) holding the guide plate (2) to the upstreamshaft

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

1 Static leak differential pressure creator assembly (see parts list )
2 Differential pressure gauge 0-10 psid or greater with sufficient static pressure
specifications to be equal or greater than the current prover pressure
3 Plumbing and valve arrangement similar to that shown in Fig 31
322Procedure
1 Refer to Fig 30 (below) and install the differential pressure gauge (1) between the
inlet and outlet ends of the prover
2 Block off inlet and outlet with flanges or blocking valves
3 Fill the prover with liquid and vent off all air from the system
4 Power up the proving computer and the SYNCROTRAK 983214

7 Install the differential pressure creator (2) in the threaded hole provided in the drive
system end plate and hand tighten (Refer to Fig 30)
8 Rotate the adjustment screw (3) Fig 30 clockwise to push the plunger out to apply
force to the piston shaft and create a differential pressure between the inlet and the outlet
of the prover Rotate the adjustment screw until a differential pressure of 5 psi has beencreated
9 Look the prover over for any obvious external leaks
10 Observe the differential pressure gauge for a period of 15 minutes if the pressure hasnot dropped by more than 25 of the starting differential pressure it may be assumedthat there are no piston seal leaks If the pressure has dropped to lower levels it should be
assumed that there is a seal leak and the prover piston seals replaced

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1941

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1541

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

33 Volumetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (See Fig 33)
2 Source of clean potable water capable of approximately 10 gpm at 25-100 psi Pump
or water supply must have steady non-pulsating pressure
3 Certified volume test measures (conforming to API chapter 4 section 7) traceable to
the US NIST (or other certifying agency if outside US) Ideally the test measure will beof the same volume as the displaced volume of the prover If however the test measure
is smaller than the prover volume there must be at least two test measures as the flow
during water draws should be continuous for the greatest precision Example For a 20-
gallon prover uses a single 20-gallon test measure
4 Certified high resolution pressure gauge 0-100 psig
5 Three traceable thermometers with 02 deg graduations see Fig 34
6 Water overboard container (volume to be at least as large as test measure andapproximately the same height
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Fig 34)
Procedure
1 Be certain that all maintenance that needs to be done to the prover has been
accomplished before starting the volumetric calibration It is advisable to perform a static
leak test prior to performing a water draw (see section 32) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water drawkit CSI item 22102233A (see Fig 32 33) Install certified thermometers and certified pressure gauge (even if the prover is equipped with P amp T transmitters) If using CSI
Water Draw P amp T kit remove downstream prover bleed valve amp install P amp T Kit
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to water draw valve controller (refer to Figs 32 33)
6 Turn water supply on and open valves V1 V2 and V3 After all air is bled off close
V2 and V3 Open V4 and V5 and allow water to circulate until the temperature has
stabilized and is not changing
7 Valve V2 may be opened slightly to allow just a very small stream of water to flow
this will bleed off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The othervalve is the draw valve and will be on only when the piston is in the measurement area of
the flowtube Also apply electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1541

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1941
19
9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

67 Volume Switch Replacement
If optical volume switch 10301049 replacement is necessary as determined by trouble
shooting procedures found in section 4 on page 22 follow steps 1 through 5
1 Remove cover 3 as shown in Fig 63 in this section to access electrical connector
2 Lift electrical connector very gently from the hole and disconnect the cable from the
switch wires (Refer to page 24)
3 With a stiff wire with a hook bent in the end or some small needle-nosed pliers gently
disconnect the switch retaining springs from the switch bar and remove the old switchPrior to dropping the switch out of position note orientation in the switch bar switch
retainer bracket
4 Install the one end of the switch retaining springs in the holes in the new optical
switch
5 Position the new switch in exactly the position noted in step 3 and reverse steps 3
through 1 for re-installation of the new volume switch
Note The CSI volume switch assembly has been precision adjusted at the factory Waterdraw after switch replacement is not mandatory

9 Place properly wetted test measures under the water draw valves
10 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
11 Water should now be draining into the wastewater container and will drain into the
wastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just before the first volume switch has been reached At the first volume switch the controllerwill signal the valves to switch and start water flowing into the test measure
12 Record the pressure (P) at P1 while only the water draw valve is open Valves V5
and V6 must be closed while recording this pressure which is the pressure at the startand the end of volume switching
13 Allow test measure to fill If one can is used which is the same as the displaced
volume of the prover one may open valve V6 to speed up the flow until the can is nearly
filled then close off V6 amp allow the calibration valve to switch back into the wastewatercontainer
14 Record temperature (T sb) at T2 which is switchbar temperature by opening the drive
cover and placing the thermometer midway between volume switches which is thelocation of the switch bar temperature transmitter thermowell
15 Record fluid temperature (T p) at T1
16 If multiple cans are used close valve V4 check level measure temperature and
record data
17 Repeat above if more test measures are to be used to contain displaced volume
18 To fill last can which must be under the solenoid valve and V6 open V6 until can is
nearly full then close V6 to allow water draw valve to perform shut off at end of volumeCarefully record can level (V ) and temperature of contents (T tm)
19 Repeat steps 9 through 19 as necessary to obtain the required number of runs
20 Calculate prover volume per section 331 below
Water Draw Notes
Perform steps 9-19 at least twice prior to taking data to purge the system of air assure the
temperature is stable and to get familiar with the procedure
Repeat the water draw procedure until at least 3 consecutive draws repeat within 002
or other repeatability criteria that the certifying parties agree upon (Flow rate on at least
one run must vary by 25 to assure integrity of prover seals and absence of leakage)
Failure to achieve the necessary repeatability may be caused by leaking valves air in the
system varying pressure leaking seals or faulty calibration technique

(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by
SYNCROTRAK reg Operation Manual

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1941
19
9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

34 Gravimetric waterdraw
Equipment
1 Water draw kit Calibron systems item 22102233A (Fig 33)
2 Precision electronic weigh scales of the correct size and resolution for example foran S25 prover balance must have a capacity of at least 200 lb and +- 001 lb resolution
(1 part out of 20000 or better resolution)
3 Certified test weight set ANSIASTM class 2 equivalent or better
4 Source of air-free or deaerated deionized or distilled water with approximately 5 gpm
at 25-100 psig steady or non-fluctuating pressure
5 A volume catch container ideally large enough for the volume of fluid dispensed bythe prover Container must be designed to be placed on the precision balance or scales
6 Certified pressure gauge 0-100 psig
7 Two traceable thermometers with 02 deg Graduations (see Fig 34)
8 Water draw data sheet Fig 36
9 Water overboard container (volume to be at least as large as test measure)
Note CSI Water Draw P amp T kit or equivalent assembly eases installation of water draw
prover instrumentation (see Figs 32 33)
Procedure
1 Perform all necessary maintenance to the prover prior to starting the gravimetric
calibration It is advisable to perform a static leak test prior to performing a water draw(refer to Fig 31) Replace the seals on the prover if there is any doubt as to their integrity
2 Block prover inlet and outlet by using a blind flange or double block and bleed valve
3 Refer to SYNCROTRAK 983214 water draw configuration Fig 31 and install water draw Pamp T kit CSI item 22102233A (Fig 32 33) Install certified thermometers and certified
pressure gauge (even if unit is equipped with pressure and temperature transmitters)
4 Connect water supply to prover refer to Fig 31
5 Connect prover control cable to controller (refer to Fig 31)
6 Turn water supply on and open valves V1 V2 V3 After all air is bled off close V2
and V3 Open V4 and V5 and allow water to circulate until the temperature has stabilizedand is not changing
7 Open V2 slightly to allow just a very small stream of water to flow which will bleed
off air which may be in the water supply
8 Apply power to the water draw circuit One of the valves will switch on immediately
Note which valve switches on and mark it as the overboard or bypass valve The other
valve is the draw valve and will only be on during the two volume switches Also apply
electrical power to the prover
8222019 Syncrotrak Manual v18k
httpslidepdfcomreaderfullsyncrotrak-manual-v18k 1941
19
9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

67 Volume Switch Replacement
If optical volume switch 10301049 replacement is necessary as determined by trouble
shooting procedures found in section 4 on page 22 follow steps 1 through 5
1 Remove cover 3 as shown in Fig 63 in this section to access electrical connector
2 Lift electrical connector very gently from the hole and disconnect the cable from the
switch wires (Refer to page 24)
3 With a stiff wire with a hook bent in the end or some small needle-nosed pliers gently
disconnect the switch retaining springs from the switch bar and remove the old switchPrior to dropping the switch out of position note orientation in the switch bar switch
retainer bracket
4 Install the one end of the switch retaining springs in the holes in the new optical
switch
5 Position the new switch in exactly the position noted in step 3 and reverse steps 3
through 1 for re-installation of the new volume switch
Note The CSI volume switch assembly has been precision adjusted at the factory Waterdraw after switch replacement is not mandatory

9 Calibrate scales with test weights totaling +- 10 of draw weight per API 494
10 With volume catch container on the scales and under water draw valve tare scales
11 To make a water draw depress the switch on the controller this will cause the prover
piston to be returned to upstream position and start the draw sequence
12 Water should now be draining into the wastewater container and will drain into thewastewater container until the first volume switch has been reached Note To decrease
the time necessary to reach the first volume switch valve V5 may be opened until just
before the first volume switch has been reached The controller will now signal the valvesto switch and start flow into the volume catch container
13 The draw can be speeded by opening valve V6 after the valves have switched to
flowing into the volume catch container Record the pressure at P1 while the draw is being conducted while only the water draw solenoid valve is open mdash not while V6 is
open Again close V6 at least 12 or 12 gal prior to solenoid draw valve switching
14 Record ambient temperature (T a)
15 Record temperature (T d ) at T2 which is detector temperature by opening drive coverand placing thermometer midway between volume switches which is in the location
of the switch bar temperature transmitter thermowell
16 Record fluid temperature (T p) at T1 (at prover)
17 Allow catch container to fill until valve switches
18 Record scale reading (W w) Drain container and retare scales
19 Repeat above procedure 10 through 17 until the desired of draws are attained
(Usually 5 consecutive draws within the desired tolerance)
20 Calculate results per 341 on following page
Note copy of Fig 36 can be used to enter draw data
Water Draw Notes
1 Perform steps 10-17 at least twice prior to taking data to purge the system of air assurethe temperature is stable and to get familiar with the procedure
2 Repeat water draw procedure until at least 3 consecutive draws repeat within 002 or
other repeatability criteria that the certifying parties agree upon (Flow rate on at least one
run must vary by 25 to assure integrity of prover seals and absence of leakage)
4 Failure to achieve the necessary repeatability may be caused by leaking valves air inthe system varying pressure leaking seals or faulty calibration technique

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by
SYNCROTRAK reg Operation Manual

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by
SYNCROTRAK reg Operation Manual

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by
SYNCROTRAK reg Operation Manual

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

them in hot water (140-150 degrees F) to make the seals and riders more flexible and toreduce the chance for damage All piston bolts should have a thread lock compound
applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the

Fig 53 401D to OMNI Flow Computer wiring and setup
An Omni flow computer requires that the meter be connected to one of the two E Combo
card pulse inputs The E combo card will use the double chronometry proving methodThe switch output VP+ (Point 7of the 401D) connects to the prover detector input of
the E Combo Card The prover detector inputs on the Omni are between Pin 7 and Pin
10 usually Pin 7The prover run command (Run+ Point 3 of the 401D) connects to any Omni Digital IO
point That point must be assigned a Boolean point that has been programmed with the
value of 1927 Then the Digital IO point must be assigned the Boolean pointExample Program the Boolean point 1025 with the statement 1927 Then program
Digital IO point 12 with the number 1025 Connect the run command wire to Digital
Point 12A resistor between 1000 to 5000 ohms (4000 to 5 000 ohms preferred) must be installed
between the ground (Point 1 of 401D) and the Run- (Point 4 of the 401D) for the runcommand to work properly This setup will launch the prover when the IO point goeshigh (voltage applied) When it is low (no voltage) the prover motor will be idle
The DC- and DC+ (Points 1 amp 2 of the 401D) connect to the Omni power supply or
any other supply that is common to the Omni A jumper must be connect between the
ground (Point 1 of 401D) and VP- (Point 8 of the 401D board)Please read the Omnirsquos Operatorrsquos manual prior to connection and or operation of the

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5

applied to them such as Locktite 242
NOTE be extremely careful to not damage the piston seals in any way or to lay the piston on the seals and cause them to be deformed
13 Insert the piston by carefully guiding the piston assembly into the flow tube beingvery careful to not damage the new seals or the precision bore flow tube It will be
necessary to apply some considerable force to the piston assembly to compress the piston
seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

seals to enter the flow tube bore It may be necessary to use a length of the appropriatesize threaded rod (58 all thread) inserted through the hole in the drive end plate where
the static leak detector is inserted (refer to fig 65) Screw the threaded rod into the piston
shaft (A piece of 12 PVC pipe over the threaded rod will prevent the threads fromhanging up in the upstream flange) Install a large flat washer and a nut on to the threaded
rod and pull the piston into the flow tube while wiggling the downstream shaft to be
certain of correct alignment with the seals and the flow tube bore
Note Refer to 63 for bolt torque values for assembling flow prover
14 Put a new seal 53002 on downstream flange 53001 carefully re-install flange intoflow tube Re-install hex socket bolts (item 53003) securing the downstream end flange
53001 to the flow tube Snug bolts evenly using a cross pattern so as to not damage the
seal or distort the flange Refer to 63 bolt torque specifications and carefully tighten bolts evenly by using a cross pattern and moving in increments to the full torque value
15 Refer to fig 66 and remove the shaft seal housing 53109 from the downstream stop 53101 by removing the hex socket bolts and remove the retaining ring seals and
washer from the housing Note the direction of the seal lips for correctly installing the
new seals

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

6 PROVER MAINTENANCE
61 General Prover Maintenance Information
The CSI SYNCROTRAK reg flow prover is relatively simple and requires very littlemaintenance except for periodic replacement of seals There is no hard and fast rule as to
the frequency of seal replacement Frequency of usage of the prover product lubricatingqualities operating temperature and amount of product contamination with abrasives all
affect the life of prover seals Poor prover performance verified with a static leak check
section 32 can determine if seal replacement is necessary Often customers replace seals
prior to periodic water draw certification
This maintenance manual covers most of the routine maintenance procedures to be
performed on your prover A trouble shooting guide is contained in Section 4 Trouble
Shooting along with wiring diagrams and schematics common to all SYNCROTRAK reg
prover models found in Section 5
Please contact the CSI factory for information on problems or repairs not covered by

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil

66 Drive System Maintenance
The SYNCROTRAK reg Prover mechanical piston return mechanism is rugged and
trouble-free requiring little maintenance All bearings are sealed and chains are stainlesssteel Maintenance on the drive system normally would be done at the same time as
normal prover maintenance such as seal change and water draw If at any time the piston
return chains need adjustment adjust only the bearings at the end closest to the flow tube(Fig 63) Adjust chains for even tension
A Chains should be lubricated with a dry chain lube or lubricant that has a carrier fluidwhich evaporates and does not cause dirt and dust to collect Recommended is a TFE
filled chain lube for bicycles and motorcycles
WARNING Do not lubricate chains with normal oils which collect dirt and cause wear
B Gearbox oil level should be checked periodically Oil level should be approximately
12 below vent port for horizontally mounted provers (see fig 69) Gearbox was filledat the factory with Mobil SHC 626 gear oil (ISO viscosity 68) If the oil level is low
drain the remaining oil and refill the reducer to the correct level - do not mix types of oil
