The INVALCO Turbine Flowmeter is a device used to measure the volumetric flow of a fluid. The flowmeter consists ofthe body, a multiblade rotor (usually 6 to 10 blades depending on size), bearings and supports for the rotor. As a fluidpasses through the flowmeter the rotor spins. The speed of the rotor is directly proportional to the fluid velocity or flowrate.
As the rotor spins, the balde tips pass through a magnetic field generated by permanent magnets in a pickup coilmounted in close proximity to the rotor but separated from it and the process fluid by the wall of the flowmeter body.
Each time a blade passes the magnet, it generates a small alternating current in the pickup coil. (See Figure 7) Thepickup coil is attached to the pickup by two terminals or wires.
Each rotor blade passing through the magnetic pickup flux lines produce one alternating current cycle. Depending onthe flowmeter size, a certain number of pulses are produced for each volumetric unit of liquid passing through the turbineflowmeter. This is known as the “K-Factor” of the turbine flowmeter. The variation of this factor over the specified flowrange is the Linearity or accuracy of the flowmeter.
Note: Meter shou ld be insta l led wi th ten diameters of stra ight pipe the same size as turb ine meter bore up and 5 stra ight pipe diameters dow nstream of meter .
Note: If valve is to be used, i t must be downstream from the meter. This is necessary not only to keep the l ine ful l for accuracy in batching appl ications, but to prevent damage caused by str iking an empty m eter with a high veloci ty stream.
Control valves should always be located downstream from the flowmeter. If a line is empty and a valve is opened, the
high velocity fluid stricking the flowmeter can cause severe damage. Air eliminators should be used in cases wheregases are flowing in the process stream. Air in the liquid will cause the flowmeter rotor to spin at a different rate than theliquid giving incorrect readings.
Spools should be installed in the flowmeter position during start up to prevent damage to the flowmeter from solids(welding slag, rust, scale, etc.) in the process liquid.
Note: Sleeved bear ings used in INVALCO flowm eters are lubr icated wi th the process f lu id . Never spin the f lowmeter at high speeds wi th ai r . Always co nf i rm that the f low l ine conta ins f lu id at star t up.
The life of the flowmeter can be extended by using a mesh filter in the flow line. Table I shows the recommended filter forvarious sizes of flowmeters.
Mechanical Installation
Turbine Flowmeters are affected by upstream and downstream piping configurations. Upstream piping has apronounced effect on flowmeter performance making it necessary to have ten (10) straight pipe diameters up-stream of the turbine flowmeter and five (5) pipe diameters downstream of the turbine flowmeter. Flowmetersshould be installed with the arrow marked on the body pointing in the direction of flow.
Thread the magnetic pickup into the mounting bosslocated on the top of the flowmeter. If the pickup doesnot have wire leads included, connect the signal cableto the pickup by threading on the keyed connector.
Note: Hand Tighten Only. Use of tools to t ighten
the pickup can damage the f lowm eter and pickup.
Turbine Meter Maintenance
Removal of Flowm eter Internals
Cartridge Type Sizes 3/4 Inch thr oug h 2” (Figure 3)
The cartridge type turbine flowmeter utilizes internals as-sembled into a single part, eliminating the need for the threepart internals kit.
Note: This type of internals is not interchangeable with anyother body type.
1) Remove the magnetic pickup.
2) Identify the upstream end of the meter by locatingthe two grooves visible from the outside of one end.
3) Remove the retaining ring from the end of the flowmeter identified by the grooves.
4) Slide the internals out of the flowmeter. It may benecessary to push the internals out by gently applyingpressure to the opposite end.
5) Inspect the internal bore of the flowmeter for defects.The internal surface of the flowmeter should be
smooth. If the surface is damaged, the flowmeter
body should be replaced.6) Inspect the internals kit for damage or wear. If it ap-pears to be damaged, replace it with a newinternals kit.
Replacement of Flowm eter Internals Cartridge Type Sizes 3/4 Inch thro ugh 2 Inch
1) Identify the upstream end of the turbine flowmeter bylocating the two grooves visible from the outside of oneend.
2) Identify the upstream end of the turbine flowmeter inter-
nals by locating the end with a cone recessed betweentwo supports forming a “V”.
3) Insert the end opposite of the recessed cone into thegroooves located in the upstream end of the turbine flowmeter body.
4) Slide the flowmeter internals into the turbine flowmeterbody until it seats firmly against the downstream end.
5) Insert the retaining ring into the upstream end of the tur-bine flowmeter, pushing it far enough into the flowmeterbody to engage the retaining ring slot directly above theturbine flowmeter internals.
Removal and Replacement o f Flowm eter Internals Size 4 Inch (Shipped B efore Apr il 1990) and Size 3 Inch Shipped Before January 1989
1) Locate the flow direction arrow on the turbine flowmeter body, or the words “Inlet” or “Outlet” stampednear the ends. Set the flowmeter body on end withthe outlet map.
2) Assemble the rear support assembly, giving atten-
tion to aligning the grooves in the pinion bolt with theslots in the cage.
3) Install the lock washer and nut. The threads on thepinion bolt should only extend halfway through the nut,(about 2-1/2 turns).
4) Insert three vanes with the tapered bottom edges match-ing the sloping bottom of the grooves in the pinion bolt.
5) Locate the three wide and shallow grooves running in alength-wise direction in the turbine flowmeter body.
6) Insert the support assembly into the body, bearing endfirst, with the vanes sliding down the shallow grooves.The assembly will come to rest against a shoulder.
7) Rotate the entire support assembly about 60 degrees,so that the vanes are no longer lines up with the ac-cess grooves in the body.
8) Tighten the nut slowly, working the assembly backand forth so the vanes will seat properly. Tighten thenut secruely.
9) Turn the body over and slip the rotor onto the rearbearing just installed.
10) Assemble and install the front support in the samemanner. It may be necessary to pull or push on thepinion bolt to work the assembly in far enough to readthe shoulder, before rotating. The pinion bolt is pulledback, the vanes are forced outward.
The rear pinion bolt can be identified by the 1/2 inch diam-eter carbide bearing which protrudes 1-7/32 inches.
The rear pinion body, or cage, can be identified as follows:
4 inch flowmeter front and rear cages are identical.
3 inch (shipped before January 1989) front cage overalllength is 2-21/32 inches and the slots begin 3/8 inches fromthe open end.
Rear cage overall length is 2-15/16 inches and the slotsbegin a little over 3/4 inch from the open end.
Removal of Flowm eter Internals

1) Remove the internals by retracting the set screw and rap-the sliding vane, if necessary, to relieve the locking pres-sure.
2) If spirolox rings are installed, remove them before attempting to remove the supports.
3) Remove the rotor support fromt he flowmeter.
4) Remove the rotor from the flowmeter.
5) Repeat steps 1 through 3 to remove the second support.
Replacement of Flowm eter Internals
Size 4 Inch (Figu re 5)
1) If your flowmeter body is grooved for spirolox rings, it isrecommended that the rings be installed.
Note: Lock rings are provided to absorb shock andshould be replaced when replacing the internals.
2) Advance the sliding vane with the set screw until the wholesupport assembly fits closely in the bore of the flowmeter
body.
3) Position the support assembly against the shoulder in theflowmeter body and tighten the set screw.
4) Install a spirolox ring if a groove has been provided for.
5) Meter bodies shipped after December 1, 1970 have threegrooves machined in each end. The sliding vane has an“ear”, detail “B”, to engage one of these grooves. The frontsupport assembly should be positioned so that the slidingvane engages the upper-left-hand groove. The sliding vaneon the rear support should engage the upper-right-handgroove. Both sliding vanes should be in line.
6) For installation in older bodies (prior to December 1, 1970),which are not grooved, the sliding vane can be turnedupside down (Figure 5) so the ear is buried in the support.
Flow in the turbine flowmeter is sensed by a non-wetted sensor called a variable reluctance magnetic pickup. Themagnetic pickup is an assembly consisting of a permanent magnet and a coil bobbin on which several hundred turns ofwire are wound (Figure 6). This combination produces a magnetic field at the top of the pickup. The pickup is placed inclose proximity to the rotor blades, but is separated from it and the process fluid by the wall of the flowmeter housing. Asthe rotor turns, the blades disrupt the magnetic field of the pikcup and generate a sine wave voltage signal across theterminals of the magnetic pickup coil. Each time a rotor blade passes through the magnetic field, one alternating current
(AC) cycle is generated (Figure 7). The number of pulses produced by a turbine flowmeter per gallon of water is knownas the “K-Factor”.
Magnetic pickup assemblies may require an enclosure to assure protection against the environment. Three types of enclosuresare available. These are:
WAK -2 Weatherproof Adapter
This kit provides an enclosure for the magnetic pickup toprotect it from physical damage, weather, hose down or highhumidity environments. A one inch (1”) NPT outlet is pro-vided at the top for the adapter for a conduit connection. Theadapter is provided with a factory installed cable clamp de-
signed to squeeze the cable for weather-proofing. Whenconduit is used, the cable clamp is removed.
EAK-2 Explosion-proof Ad apter
This kit provides an explosion-proof enclosure for themagnetic pickup. The enclosure is rated Class I, Divi-
sion I, Group D. The enclosure is provided with a oneand a quarter inch (1-1/4”) NPT connection for conduit.
EAK -2AX-P Explos ion-proo f Adapter with Terminal Bloc k (Figure 10) This kit provides an explosion-proof enclosure with a 3 point terminal strip. The enclosure is provided with either atwo wire lead magnetic pickup, a pre-amp magnetic pikcup (requires a 5 to 32 volts DC external power) or an RF
pickup (requires 5 to 26 volts DC external power).
Model EAK-2BX-P Explosion-proof adapter with RF orTransmission Signal Pre-amptype pickup. 8” cable withmating connector and termi-nal strip.
Model EAK-2AX-P Explosion-proof adapter with wire leadmagnetic pickup and 3 pointterminal strip.
All INVALCO repair parts kits include all flowmeter internal components. The assembly is calibrated on water at70°F, with a viscosity of 1 centistoke. Each repair kit has a K-factor guaranteed to be within +/-1 percent of theoriginal.

The INVALCO 3-A (28-03) Sanitary Turbine Flow meter is certified for use in the food and beverage industry where3-A is required. The meter has been specially designed to have the same characteristics, flow ranges, and life asall the Invalco industrial meters, and also meet or exceed the requirement of 3-A (28-03). The meter has amaximum surface finish of 32ra on all internal parts; all components are manufactured out of 3-A approvedmaterial, and can be cleaned in place to save time and money in disassembling cleaning and reassembling themeter. The wear surfaces are made from FDA (3-A) approved carbide for superior wear resistance.
The meter can be cleaned as long as the following conditions are met:! Caustic solutions that are acceptable with 316 stainless steel components
! Temperatures of less than 275ºF (135ºC) for less than a 60 minute duration
! Instantaneous flow Ranges of the fluids must never exceed the chart below.

3 60-600
! Air purging must be done with care not to create severe shock loading to the meter, and velocity through themeter must not exceed the instantaneous published flow ranges of the meter.
! Radii at ends of meters and the thrust bearing pockets (see figure 14) must be periodically checked forcleanliness and adjustments in cleaning may be required to clean these areas. If areas do not clean in placethe meter may need to be disassembled from the line and cleaned by hand or other method to insure propercleanliness is being achieved. If the meter is disassembled for cleaning or inspection, care must betaken not to lose the thrust bearings located at either end of the shaft. All replacement internals utilize asanitary paste to ensure that the bearings remain in place during assembly.
The Model 4200 Rate/Totalizer is designed to accept fre-quency or pulse inputs from a wide range of flowmeters andto display flowrate and a re-settable total directly in engineer-ing units. Scaled pulse output is standard. The Model 4200is fully programmable with K-Factors, linearization of multipleK-Factors, decimal point positions, and timebase being pro-
grammed via the front panel switches. The instrument ishoused in a durable weatherproof polycarbonate enclosurethat can be mounted directly on a flowmeter, panel mountedor wall mounted using a pivoting bracket.

Program Steps
1. Hold the “Program” button for 5 seconds. This willput the 4200 into programming mode.
2. The first time that the 4200 is setup, the programwill take you directly to the K-factor entry screen. The
4200 will now prompt for using a single K-factor or tolinearize using multiple K-factors. Selecting “oFF” willuse a single K-factor (go to Step 3). Selecting “on” willallow the input of multiple K-factors (go to Step 4).
Button operation:
“Program” = progress to next screen regardless ofwhere cursor is positioned
“Enter/Next” = move cursor left one position
“K-factor” = move cursor right one position
“+” = increments number where cursor is positioned
“-” = decrements number where cursor is positioned
“Reset” = replaces numbers with default and returnsthe cursor to the right most position
3. Input the appropriate K-factor. Insertion of the
decimal position is the last step required to
input a new k-factor. After the last numerical
position is entered, the “+” and “-” buttons willmove the decimal position through the 3 posi-
tions. After placing the decimal in the correct
position, the “Enter/Next” button will progress
the screen. If linearization is required proceed
to Step 4. If linearization is not required pro-
ceed to Step 7.
Button operation:“Program” = progress to next screen regardless of where cursor is positioned
“Enter/Next” = move cursor left one position “K-factor” = move cursor right one position “+” = increments number where cursor is positioned “-” = decrements number where cursor is positioned “Reset” = replaces numbers with default and returns
the cursor to the right most position
4. Input the 1st pulse rate (Hz) starting with the lowest.
Button operation: “Program” = progress to next screen regardless of where cursor is positioned
“Enter/Next” = move cursor left one position “K-factor” = move cursor right one position “+” = increments number where cursor is positioned “-” = decrements number where cursor is positioned “Reset” = replaces numbers with default and returns the
cursor to the right most position
5. Input the 1st k-factor matching the 1st pulse rate
entered in the previous step. Insertion of the deci-
mal position is the last step required to input a
new k-factor. The decimal position is limited to 3
positions. After the last numerical position is
entered, the “+” and “-” buttons will move the
decimal position through the 3 positions. After
placing the decimal in the correct position, the
“Enter/Next” button will progress the screen.
Button operation: “Program” = progress to next screen regardless of where
cursor is positioned “Enter/Next” = move cursor left one position “K-factor” = move cursor right one position
“+” = increments number where cursor is positioned“-” = decrements number where cursor is positioned “Reset” = replaces numbers with default and returns the
cursor to the right most position
6. Repeat step 4 and 5 for as many different pulse
rate and k-factor combinations up to 10 entries. If
you have less than 10 combinations to enter, enter

13. At this point the user has the option to establish a
password. Once a password has been set, the 4200 will
always prompt the user for a password, before pro-
gram changes can be made. When no password or the
wrong password is entered, the 4200 will go back to
the normal display. THE ESTABLISHMENT OF A
PASSWORD IS OPTIONAL. If locking the 4200 with a
password is not needed, enter “000000” and the 4200
will operate unlocked. **
Button operation: “Program” = progress to next screen regardless of where cursor is positioned “Enter/Next” = move cursor left one position “K-factor” = move cursor right one position
“+” = increments number where cursor is posi-tioned
“-” = decrements number where cursor is posi-tioned
“Reset” = replaces numbers with default and re- turns the cursor to the right most position
** It is highly recommended that thepassword function not be used unless itis required. If a password is requiredwrite down the password in the manualand keep in a secure location. If you forget the password you must con- sult the factory for procedures onhow to reset the current password.
14. Now the 4200 will prompt for user to acceptthe password. Display should read 000000 in RATE
area of LCD if no password is required
Button operation: “Program” = return to password screen (step 14) “Enter/Next” = accepts password and exits program
mode
“K-factor” = return to beginning of setup “+” = return to password screen (step 14)“-” = return to password screen (step 14)“Reset” = return to password screen (step 14)

Changing Batteries
New batteries can be purchased through INVALCO or our distributors and replaced in the field.
WARNING - To prevent ignition of flammable or combustible atmospheres, read, understand, and adhere to the manufacturer’s live maintenance pro-
cedures.
Replace battery with an INVALCO battery assembly ONLY. Battery assembly part number is P524017. Themodel 4200 is designed to operate on one battery.NEVER attempt to power the unit with two battery as- semblies or with a non-INVALCO battery assembly.
There is one Lithium battery pack in each instrument andcare must be taken to replace so that there is always power connected to the memory. Connect the new battery packinto J3 or J4 before disconnecting the old battery. Failure tonot supply the board with continuous power will result in lossof setup parameters and totals. Please dispose of old
batteries by sending them to an Approved Battery Recycle Location.
Typical Connections
Flowmeter Input The Model 4200 input circuit which will accept signalsfrom most pulse or frequency producing flowmeters.The input will interface directly to:Turbine FlowmetersFor flow meters with coils, the minimum input voltage is20mV P-P. See the drawing below and sketches on thenext two pages for hook-up information.
1. Squarewave, CMOS or Pulse2. Reed or Switch5. Coils (Magnetic Pick-up)
Wiring
When connecting the 4200 it is good practice to use ashielded cable. The shield should be connected toearth at one end of the cable. The other end of theshield should not be connected.
A wall mounting bracket is supplied with each instrument.The instrument is then attached to the bracket atthe bottom with knobs.Removing the Front Panel:The front panel of the instrument is removed as follows:
1. Loosen knobs and tilt unit down.2. Undo the eight screws retaining the front panel.3. Pull the front panel free from the housing.
Unit can then be tilted up to access internal components.

The 4200s are affected by EMF (Electric MagneticFields); due to this the unit needs to be located in anarea with little affects from externally omitting EMFdevices. The turbine and pickup uses EMF in pulsesto calculate rate. Interference in this field by otherdevices will cause inaccuracies with the meter. Elec-tric motors, spark driven engines, transformers, andother high current or high voltage devices create EMFand should be kept as far away as feasible to lessentheir chances of effecting the meter.
Vibration can cause false readings or counted ratewhen not in use. Portable units should be reset aftertransport to re-zero the meter. Place meter in a loca-tion where it is well grounded, free of vibration andstable when metering.
When installing the Model 4200 in hazardous areas, the wiring and installation must comply with appropriate installa-tion standards. The Model 4200 will connect directly to turbine or paddlewheel flowmeters with a certified IS coil or other certified IS sensors which produce a pulse output, provided they do not exceed the following input parameters:
Vmax = 3.6 Vdc
Imax = 72 mA
Ci = 12.34 uF
Li = 0 mH
