Description
Smith Meter double-case rotary meters are of the positivedisplacement type. The F4 PRIME upgrade uses a similarinner unit as that utilized in a standard F4-S1 PositiveDisplacement meter. Its double-case design eliminatesdistortion of the measuring chamber due to pressure dif-ferential and piping strains. Pipe connections are con-fined to the outer housing which means the measuringelement can be removed by taking off the meter coverassembly and lifting it out. Inspection, maintenance, andservice is greatly simplified through the double-case de-sign.The measuring function is accomplished in a chamber ofprecise volume created by the reciprocating blades, ro-tor, body, and cover. As liquid flows through the meter,the rotor and blades revolve about a fixed cam causingthe blades to reciprocate. The successive movement ofthe blades form a measuring chamber of precise volumebetween two blades, the rotor, the housing, the bottom,and the top covers. A continuous series of these closedchambers is produced as the rotor revolves. Neither bladenor rotor contact the stationary walls of the measuringchamber (Figure 1).
The F4 PRIME upgrade provides a meter variation withpolyketone blades and a super-hardened cam which al-low the meter to operate at higher speeds and increasesthe flow rate from 600 gpm (2,300 L/min) to 800 gpm(3,030 L/min). It provides a direct pulse output which elimi-nates the need for a packing gland and gear train. A self-aligning thrust bearing made of polyketone and surfaced-hardened steel minimizes wear and extends meter lifeimproving meter performance. It makes good sense toupgrade existing Smith Meter F4 PD meters rather thanreplacing them. The F4 PRIME upgrade is less expensiveand offers improved performance and reliability over oldermeters.
Quick Reference
Installation of F4-S1/A1-S3/A3 PRIME Inner Mechanismand Cover Only - See Service Bulletin (PublicationSV01007)Installation/Operation/Wiring of Complete Meter - See In-stallation and Operation Bulletin (Publication MN01037)For F4-S1/A1-S3/A3 PRIME Upgrade Specifications -See Specification Bulletin (Publication SS01097).
Introduction
This manual provides detailed information to upgrade astandard Smith MeterTM Model F4 PD Meter to the F4PRIME upgrade. This affordable upgrade will improve reli-ability, extend the flow range, and allow for direct pulseoutput. See related publications for Specifications, PartsLists, and Installation/Operation information pertaining toyour specific model of meter.
Double-case meter construc-tion features ease of mainte-nance and service. For ex-ample, the measuring unit canbe removed vertically from theouter housing with little spill-age and without disturbingpipe connections. Also, com-plete metering units and partsare interchangeable. As a re-sult, the simple removal anddisassembly steps encourageperiodic preventive mainte-nance inspections.
It is suggested that detailed records be maintained foreach meter installation, such as nameplate data, clear-ances, progressive totalizer readings, meter factor, partsused, and other similar information, that will provide back-ground material for scheduling preventive maintenance.A chart of meter factor versus throughput can be used asthe basis for making an inspection.The time of the first inspection must be based on theoperating conditions imposed by the installation. Flow rate,lubrication properties of the fluid, and the possibilities ofabrasive contaminants are points to consider. Then, atthe time of inspection, the condition of the meter shouldindicate whether the inspection interval can be length-ened or shortened.When ordering parts or inquiring about a unit, be sure toinclude complete model and serial number informationfrom the nameplate.Note: Meters constructed to special specifications (des-ignated by a six-digit serial number) may have clearancesin variance to those shown in this manual. Consult yourrepresentative or the factory for the correct informationregarding your meter.

Total end clearance is divided between the top andbottom. To set the rotor adjustment, loosen theadjusting bolt locknut and turn the adjustment boltclockwise. While turning the rotor by hand, slowlylower the rotor assembly until it just begins to bindagainst the base. Mark the position of the adjust-ment bolt to the cover and slowly raise the rotorassembly (turning the adjustment bolt counterclock-wise) unit until it just begins to bind against thecover. Mark the position of the adjustment bolt tothe cover. By means of the adjustment bolt, lowerthe rotor until 1/2 of the clearance is off the top and1/2 is at the bottom. Use the two marks on thecover as reference. (Refer to Rotor Adjustment -Total End Clearance (F) Page 14.)
17. Install the inner mechanism into the meter housing.Make sure inlet and outlet ports are thoroughly cleanedbefore installation. Do not use a scraper or screw-driver on the machined surfaces. Coat both machinedinlet ports with Loctite Master Gasket or other sealingmedium. Lower the inner mechanism into the meterhousing. Apply Master Gasket or other sealing me-dium to the inner mechanism body bolts and tightento draw inner mechanism up to seal the inlet port.
18. Coat the cover O-Ring with petroleum jelly and installO-Ring in groove of outer housing. Install the F4PRIME upgrade cover. Align the cover to the locatingdowel pins in the meter body with the appropriatedowel pinholes in the cover to ensure correct align-ment between the jackshaft coupler and link assem-bly. By placing the cover bolts in the cover aides inthe alignment (Figure 31). You will need to use asmall pry bar to raise the cover to ensure you havecorrect alignment and engagement between thejackshaft coupler and exciter gear link assembly. Ifyou have difficulty making alignment between thejackshaft gear and exciter gear link, remove the sen-sor housing to rotate the gear by hand until appropri-ate alignment is made (Figure 33).

Clearance Checks
Clearances should be checked with a leaf-type feeler gaugeand compared to the Clearance Guide - Table 2. Anyaverage of clearances that are outside the recommendedclearance in Table 2 should be noted. Certain parts maybe at or over the maximum recommended clearance. Con-sideration should be given to the condition of the part andthe accuracy obtained during meter calibration. Certainmajor parts such as the rotor, cam, and blades need notbe replaced if the meter calibration records show no appre-ciable change in accuracy between provings.The specified clearances are highly desirable and all rea-sonable effort must be made to achieve them. However,due to the number of individual parameters which affectthe final clearance (e.g., dimensional tolerance, geomet-ric conditions, general variability in manufacturing), indi-vidual parts may need dressed with crocus cloth or a finefile.
Blades should move freely in rotor slots and the averageclearance should not exceed the recommended clear-ance, nor shall any single point exceed 50% above the
Figure 38 Figure 39
Less than 2,000 SSU (400 mPa•s).
Caution: When dressing rotor slots, block, or blade, be careful not to remove too much material. The bladesshould have sharp, clean cut edges. Record all measurements in the “as assembled” clearance record.
maximum clearance recommended in Table 2 (Figure 38).Blade Slot Clearance (C): If blade slot clearance doesnot meet recommended clearance, rotor should be re-placed. When installing a new rotor and blade slot clear-ance does not meet minimum recommended clearance,rotor slots may need dressed with a fine file.
Blade Top End Below Rotor Clearance (D)
Special tools required:Depth Micrometer - 1”
Place the depth micrometer on top of the rotor assemblyover the blade. The blade should not project above therotor. If the blade extends above the rotor, it can be dressedwith a sanding block with crocus cloth. If the blade isbeneath the rotor as specified in Table 2, replace theblade (Figure 39).Blade Top End Below Rotor Clearance (D): If bladetop is above rotor, blade top should be dressed with asanding block and crocus cloth. If blade top exceedsbelow-rotor-recommended-clearance, blade should bereplaced.

Issue/Rev. 0.2 (3/01) MN01039 • Page 13
Blade Tip to Housing Clearance (A)
Special tools required:Spider (Figure 2)Feeler Gauges, Leaf-Type (Table 1)
With the rotor assembly installed in the inner mechanismhousing, place the spider over the cam shaft and secureinto housing. Turn the rotor assembly until a blade is fullyextended (for each blade paddle) and measure the dis-tance between the blade tip and housing (as shown inFigure 40) using a feeler gauge, leaf type (Table 1). Blademust be forced toward housing to account for the bladefollower.The minimum clearance specified is optimum but localpoints may exceed the maximum clearance recommendedup to 25%.Blade Tip-to-Housing Clearance (A): With rotor assem-bly installed in the inner mechanism housing, install spi-der. Blade tip-to-housing clearance can be checked byrotating the rotor assembly until a blade paddle is fullyextended. Measure between the blade tip and housing. Ifmeasurement does not meet minimum recommendedclearance, dress the blade tip with a sanding block andcrocus cloth until proper clearance is achieved. If clear-ance exceeds recommended clearance, replace the blade.
Rotor to Block Clearance (B)
Special tools required:Spider (Figure 2)Feeler Gauge, Leaf-Type (Table 1)
The clearance between the rotor and block should bemaintained the full length of the rotor.The clearance can be obtained at any point between therotor and block and should meet the recommended clear-ance in Table 2 or meter accuracy may be affected (Fig-ure 41). The minimum specified rotor-to-block clearance isoptimum but the maximum clearance taken may be ex-ceeded in local areas by no more than 25%.
Figure 40
Figure 41
Rotor-to-Block Clearance (B): If rotor-to-block clearancedoes not meet minimum recommended clearance, blockshould be removed and the necessary clearance can beobtained by dressing the back of the block with a fine file.If clearances exceeds recommended clearance, replacethe block.
With the blade in the measuring chamber, the total clear-ance should be maintained between the radius of thecam and one blade roller (follower) only.To measure blade roller (follower) clearance over radiusportion of cam, insert feeler gauge and check throughradius.With the rotor assembly in the inner mechanism hous-ing, the blade follower over cam radius clearance canbe obtained by positioning the blade in the middle ofthe measuring chamber. This will position the bladefollower over the cam radius. Carefully push the bladetoward the measuring chamber and take measurementbetween blade tip and housing. (Precaution: the bladewill tend to rise at one end and can give an incor-rect measurement.) Then, push the blade toward theblock and repeat measurement. The difference betweenthe two measurements will give the blade roller (fol-lower) clearance.With the rotor assembly on the wood box (Figure 2),place magnetic dial indicator on rotor segment and po-sition dial indicator on blade tip. Make sure blade ispositioned over cam radius and move blade back andforth to obtain reading from dial indicator (preferredmethod).Blade Follower-to-Cam Radius Clearance (E): If clear-ance does not meet recommended clearance, replacethe blade.
