Meters utilized in the natural gas industry are divided into twogeneral categories: inferential or positive displacement.

The inferential category includes turbine and orifice meters.Turbines are also referred to as velocity meters as they mea-sure the gas velocity flowing through a pipeline.

Meters in the positive displacement category are the dia-phragm and rotary types.

Rotary gas meters have been utilized in the industrial andcommercial markets for decades and were produced in vari-ous designs. For today’s gas utility, the rotary’s primary appli-cation is to fill the flow gap between the diaphragm meter andthe turbine meter. Like the diaphragm meter, the rotary metermeasures gas with compartments that alternately fill andempty.

In addition to non-residential applications, many productionfields or well head users utilize the rotary meter to provideaccurate well head measurement at various pressures. Whenproperly sized, installed, and maintained, the rotary meterprovides accurate and dependable measurement from low tohigh pressure applications for many years.

�������� ����� ���

The rotary meter is suitable for measuring most types of cleancommon gases. It is NOT intended for handling liquids, acety-lene or sewage gas, and its operation/accuracy can be af-fected by excessive deposits of dirt or other foreign materialscarried in the gas stream.

The basic type of rotary meter utilizes two opposite rotatingtwo-lobe impellers. Internally there are no contacting parts inthe measurement chamber. As adjusted from the factory, thereis usually no wear as long as the meter is kept clean, leveled,and the bearings are properly lubricated.

The opposite rotating “figure 8” impellers of a rotary meteroperate within a rigid casing that has inlet and outlet gasconnections on opposite sides.

The impellers rotate as a result of the pressure drop across themeter as downstream gas is consumed. The rotating impellersseparate the flowing gas stream into small segments beforethe gas enters the downstream piping. These small segmentsare counted using a gear train which drives the meter index orcorrecting instrument. See Fig. 1-2.

Position 1 As the bottom impeller rotates in a counter-clockwise direction toward the horizontal posi-tion, gas enters the space between the impellerand the cylinder.

Position 2 At the horizontal position, a definite volume ofgas is contained in the bottom compartment.

Position 3 As the impeller continues to turn, the volume ofgas is then discharged.

Position 4 Concurrently, the top impeller rotating in theopposite direction has closed to its horizontalposition, confining another known and equalvolume of gas.

This process is repeated four times for each complete revolu-tion of the impeller shafts.

There are four considerations to take into account whenselecting and sizing a meter:

1. Inlet pressure

2. Required flow

3. Type of customer

4. Required pressure

Additionally, when selecting a rotary meter for a specificinstallation, the normal minimum and maximum allowableoperating pressure (MAOP) should always be considered.

Industry standards recommend sizing rotary meters for 60% ofthe rated capacity and not lower than 10% of capacity. Be-cause of the “no contacting parts” design, some gas can seepthrough the meter creating an error at low meter speeds.

AMERICAN METER CO. recommends that the meter be sizedso it will NOT OPERATE below 10% of its rated capacity forlong periods of time. Low flow rate error is corrected eachtime the rotary meter operates at 10% or more of its ratedcapacity. Above the 10% flow rate, the meter’s accuracy isslightly greater than 100%, and this compensates for possibleerror at low flow or pilot load flow rates.

The following example depicts an “average day in accuracy ”measurement from a rotary meter:

A 5.5M rotary meter measuring natural gas consumption at abakery that operates 16 hours a day:

Gas Consumption Meter Accuracy16 hrs x 4000 CFH = 64000 x 100.5% = 64320

+ 8 hrs x 300 CFH (low flow) = 2400 x 98.0% = 2352

24 hrs = 66400 vs. 66672(actual) (registered)

66672 — 66400 Average Daily Accuracy = 100.4%

Installation

������ �������� �

When installing a rotary meter, it can be easy to overlookdetails that may hinder meter performance and maintenance.Usual emphasis is put on a clean gas flow through the meterby use of filtration and proper inlet and outlet piping. There aresome DO'S AND DON’TS that should always be consideredwhen designing a rotary meter set.

• Refrain from using excessive amounts of pipe dope oninlet piping to the rotary meter. Chunks of pipe dopecan break loose from screwed fittings and fall onto andin-between impeller lobes, rendering the meter immedi-ately inoperative.

• Check for excess dirt, scale and weld splatters in thepipeline.

• Install an in-line pipe screen filter upstream from themeter to keep debris (i.e., stones, tap shavings, scale,and weld beads) from entering and causing damage tothe meter.

The use of an AMCO 80 mesh strainer is stronglyrecommended. See the parts list in the back of thisdocument (Page 5.6) for ordering information. Theelimination of smaller contaminants (i.e., grit) can beachieved with an AMCO KleanlineTM micron filter.

• If selecting full-port valves for the inlet and outlet piping,always use ball valves that require no, or minimallubrication to achieve tight shut-off. Excessivelygreased plug valves will degrade rotary meter perfor-mance due to lubricant seeping into the meter.

• AMCO recommends if possible, installing a straight runof pipe without restrictions (i.e., valves, regulators, etc.)for a distance of six pipe diameters on either side of themeter (Fig. 2-1). This optimum set design will prevent areduction in meter accuracy resulting from a turbulentgas stream.

Installation

• Bypass piping can effectively reduce time spent ondifferential testing and maintenance. If a combinedmeasurement and regulation set is installed, metertesting and regulation inspection can all be completedat the same time with minimum disruption of service.

Bypass valves should have a tamper proof lock or sealto prevent theft of gas.

• Adequate service (working) clearance around themeter should be maintained to allow easy access forreading the meter indexes. For temperature compen-sated meters, a 6" clearance space for the temperatureprobe is necessary to permit the removal of the TCcounter module if necessary. Clearances are alsorequired for differential testing access, inspection andnormal lubrication maintenance.

• The meter should never be installed so that it is lowerthan the discharge pipe runs. This would allow themeter to become a sump for condensate and otherforeign material.

Unpacking instructions are also included in the shippingcontainer.

American RPM Series meters utilize packaging that meet ISTA(International Safe Transit Association) test specifications.Even with the packaging’s rugged construction, the metershould be handled with care in transport and storage to protectits factory certified accuracy.

NOTE: If outer package shows evidence of damage throughmishandling in transit, NOTIFY the shipper and immediatelyperform a careful inspection of the meter. FILE a claim with theshipper if damage is indicated and also notify your local AMCOsales office. See Appendix for listing.

NOTE: All packaging has size of meter inside, and an arrowdepicting UP.

1. Carefully open the shipping container at the top seam.When cutting the top seam be careful not to cut too deeplyinto the area where the meter and accessories are lodged.

2. Open up the two top flaps and bend outward.

3. Remove the lubrication kit, instruction manual, and mag-netic wand if the meter is equipped with the temperaturecompensator. The box will also contain the certificate ofaccuracy documentation. This should be filed for furtherreference.

4. Remove the center and end cardboard dividers.

5. Carefully grasp the meter by the center of the body and liftupward. See Figure 2-2.

CAUTION: If the meter is equipped with a temperaturecompensator module, DO NOT LIFT THE METER BYTHE COMPENSATOR MODULE ON THE END.

6. Always check new meters for free rotation after removalfrom the shipping container. This procedure is described inthe following section, Check and Start-up.

7. If the meter is not to be installed or tested immediately,return the meter to its shipping container and place horizon-tally, red arrow pointing UP, in a dry, protected area. DONOT put oil in the meter until it is to be installed.

Installation

��� ����������������

• Proper support is necessary for any gas meter installation.If properly designed it provides stability and a sound baseto eliminate vibration to the meter. If the ground surface isunstable, industry standards recommend an 8"x 8"x16"solid block be used to set the inlet and outlet risers. Riserlegs should be at 90o angles from the set.

• A rotary meter can be installed horizontally facilitating thechange out of an old meter set; however the preferredinstallation is top inlet in a vertical pipeline. Vertical mount-ing allows contaminants to be expelled more easily viagravity from the meter.

• A rotary meter should be installed close to 100% level at alltimes. Deviation from level should not be more than+1/16" per foot in all directional planes. If the meter is notset level, it is possible to overfill or underfill the oil reser-voirs while the oil sight glasses indicate the proper level.Overfilling with oil can cause the meter to read incorrectlydue to increased drag on the gears and possible bleedingof oil into the measurement chamber. Underfilling metersthat are not level can lead to excessive bearing wear andwill be evident on differential testing.

��������� �� �������� ���

The following steps should be utilized to insure a trouble-freestart-up of the AMCO RPM Series Rotary Meters.

1. Remove the meter from the shipping carton and inspect fordamage that may have occurred during transit. See previ-ous section, Uncrating the Meter procedure.

2. Set the meter on the bottom of the over-turned shippingcarton and remove the protective caps from both flangeopenings.

CAUTION: Do not let dirt, debris, etc., enter flangeopenings!

3. Lightly blow into the inlet of the meter. This slight air pres-sure should cause the impellers to rotate freely and cometo a stop slowly. If the impellers do not turn, this indicates apossible foreign object within the measurement cavity andthe meter should be returned to the repair shop or manu-facturer.

4. Verify that the mating flanges or optional flanges (refer toFigure 2-3), for the meter plus the correct distance (FL) areas close to level; within 1/16" per foot in all directions.

Installation

NOTE: (FL) = Meter + (2) gaskets + 1/16" clearance.

The correct bolt sizes for the RPM series meters is5/8-11 x 1-1/2" Hex Head. All bolts should be installed withflat washers. Tighten bolts evenly. Do not over torque(max. 80 ft-lbs.)

5. Remove the center pipe plug on the rear gear cover andverify the impellers still turn freely.

6. Fill unit with correct amount of oil. See “LUBRICATION”.

7. Turn the gas supply on SLOWLY at approximately 1second per 10 psig maximum. Turning the gas on quicklycould potentially overspeed and possibly damage themeter.

CAUTION: Should the installation be subject to ex-treme “INSTANT ON” loads, the meter should beprotected from overspeeding by a restricting floworifice plate.

8. Leak test the meter and all connections.

���������

Gears and bearings in the rotary meter are lubricated by the“Dip and Splash” method. Sight plugs are located on bothends of the meter. Any sight plug or pipe plug on the endcovers can be used for access for filling with oil, dependingon the meter mounting. See Fig. 2-4.

Meter accuracy, regardless of the manufacturer, is unlikely toimprove with use. Therefore it is important to develop perfor-mance standards on the meter at installation so those stan-dards can be monitored at a future point in time.

Differential testing is used to determine changes in the meterafter installation. The test is performed using a differentialpressure manometer under actual conditions of gas flow rate,line pressure and specific gravity. In lieu of a transfer prover,differential testing gives a good indication of the operationalcondition of the meter. It does not indicate meter accuracy.

AMERICAN METER CO. furnishes a test report with eachrotary meter enclosed in the shipping carton. The test reportindicates percent rated capacity, accuracy, proof and differen-tial pressure for various flow rates of the meter. This test reportalso is kept on file by AMCO for the life of the meter.

The Appendix of this manual includes a blank chart. Theinstaller can record a performance curve on initial start-up ofthe meter. The installer should plot a point on the chart for eachdifferential at each level of capacity tested. Three points arerequired within the 25% to 100% range to establish a represen-tative curve at installation, after 5/10 years and after solventflushing. Refer to Fig. 2-6.

Field testing on gas below 15 psig can be compared directlywith AMCO factory test results on air as indicated on thefurnished accuracy test report. It is always important to test themeter under the actual conditions of gas line pressure and

���� � ������ ������������specific gravity that will exist in service. This is particularlyimportant when line pressure is above 15 psig so that a directcomparison with later tests can be made. Although as previ-ously stated, accuracy cannot be directly determined bydifferential test.

Test results have indicated that an increase of up to 50% indifferential pressure can be tolerated without affecting meteraccuracy at flow rates of 25% and above.

There are three things that can potentially affect a meter’saccuracy which would also affect the differential test results:

1. Change in the “Static Displacement”

2. Enlargement of clearances between moving parts

3. Internal resistance increase

Change in the “Static Displacement”

The U.S. National Bureau Of Standards Paper 1741, “TEST-ING LARGE CAPACITY GAS METERS,” pg. 187, states:

“The Static Displacement of a Rotary gas meterappears to be almost unaffected by deposits,even those resulting from unpurified gas.Hence, having once been determined, it willseldom be necessary to redetermine.”

Enlargement of clearances between moving parts

There is NO wearing of internal parts because the movingparts have NO direct contact with other surfaces. Henceclearances DO NOT change between the body and the impel-lers.

Internal resistance increase

Internal resistance is the most critical factor in the effects onmeter accuracy because any significant increase in resistancewill increase the pressure drop across the meter.

The most common causes of an increase in internal resistanceare: dirt, pipe dope, thread shavings between impellers, wornbearings bending torque on the body, and heavyweight orexcessive amounts of oil.

If the differential test at the time of installation is found to be50% greater than what was indicated on the AMCO factorytest results, the meter should be taken out of service and

���� � ������ ������������returned to your local AMCO sales representative for replace-ment under the terms of the WARRANTY described previ-ously.

If the differential test during normal maintenance and afterprolonged service is found to be more than 50%, the metershould be taken out of service for cleaning.

A simple flushing with mineral spirits, kerosene or your compa-ny approved solvent should easily remove the foreign materi-als within, and bring the meter back into acceptable specifica-tion.

If the flushing operation fails to bring the meter into specifica-tion, the unit should be returned to your approved meter repairshop for tear down and bearing replacement. AMCO recom-mends draining the oil from the meter end caps after blowdownto atmosphere, to prevent oil from splashing onto the impellersduring transport.

While there is no nationally established time period for testing,some states have formally adopted differential rate test peri-ods. Aside from these states, a five year test interval is gener-ally considered acceptable.

Recommended frequency of differential testing:

1. At the time of installation

2. Twelve months after initial installation

3. Every 5 years thereafter

NOTE: Always consult your company policy or state/countrycommissions for specific time intervals on differential rate testperiods.

Temperature Compensator

���� ��������� � ���� ��

All commercially used non-temperature compensated naturalgas meters are designed to meter gas at 60oF (15.6oC)(basetemperature). At 40oF (4.4oC), that meter actually passes 1.04cubic feet for every one cubic foot registered. When thishappens, the customer receives 4% more gas than they arebilled for.

If we use the example of the day in the life of a 5.5M RotaryMeter at the bakery as depicted on page1-5 of this manual;lack of temperature compensated metering can be costly inlost and unaccounted for gas delivery.

�������

The average temperature of metered gas in February in NewEngland, is 40oF (4.4oC) which is a 4% change in volume fromthe 60oF base temperature (+ 5oF = 1% change in volume).

In the 28 days of February the non-compensated rotary meterregistered 1,866,816 ft3 of gas; however, because the flowinggas temperature was 40oF (4.4oC) the bakery could havereceived 1,941,489 ft3; a loss to the utility of 74,673 ft3 of gasfor the month unless corrected for at the time of billing.

At $.70 per 100 ft.3, the financial loss to the utility for onemonth gas delivery to the bakery if uncorrected was$522.71, more than the original cost of the “optional add on”Temperature Compensator module to the meter.

Correction at billing time can also be inaccurate as flowing gastemperatures can fluctuate by the hour during normal gasdelivery. Temperature Compensation of the meter is by far the$mart choice.

������ �������� �

The RPM Temperature Compensator is a battery poweredelectronic device. It is designed to provide incremental temper-ature compensation and correct the index readings of gasmeters.

The RPM Temperature Compensator’s intrinsically safe designpermits operation in hazardous locations. UL and CSA approv-als are currently pending as of this printing.

The Temperature Compensator module measures actualflowing temperature, corrects meter readings, and constantlydisplays the corrected volume.

Temperature Compensator

Other displays and test screens are activated by a magneticwand shipped with the unit. Alarm screens are displayed asnecessary, i.e., Low Battery.

The Temperature Compensator stores in memory daily sum-mation data of corrected and uncorrected volume for thecurrent month in operation. In addition, a total monthly summa-tion history file is retained for the same data for the six (6)previous months. A complete six (6) month history is availablefor access via the unit’s downloading interface port to an on-site portable computer or transmitter via a customer suppliedmodem.

������ ���� �

As long as battery power remains connected, the RPM Tem-perature Compensator will record and update the display dataon an incremental volume basis.

Screen #1 Corrected Volume in the Display Mode is displayedconstantly without the use of the magnetic wand.

Whenever other data is to be observed, use the magneticwand to access the desired data display as described in thestart-up and display procedures.

������� ������

CAUTION: Do not lift the meter by the TemperatureCompensator.

Physical damage to the RPM Temperature Compensa-tor or removal of the cover by unauthorized personnelmay affect the intrinsically safe electrical design andoperational integrity of the unit. If either is observed,the unit should be taken out of service and notify thefactory.

Inspect the RPM Temperature Compensator and the RPMmeter installation for any obvious physical damage. All dam-aged parts must be repaired or replaced prior to start-up of theRPM Temperature Compensator. Any damage may affect theintrinsically safe electrical design and operational integrity ofthe equipment.

Tamper-proof hardware secures the cover to the case. Assurethe hardware lockwires have not been removed or tamperedwith before attempting to install the unit.

The display screen as received, displays the CorrectedVolume. The unit is shipped with a lithium battery installed and

will begin to acquire and record meter index readings immedi-ately upon installation. The average life of a single (DD)-lithiumbattery is shown of page 3-6.

The RPM Temperature Compensator can display in twodifferent modes. They are the Display Mode and the DisplayTest Mode. The first to be discussed is the the Display Mode.This is the mode which offers information on Corrected Vol-ume, Uncorrected Volume, Flow Temperature, etc.

������� � ��

The Temperature Compensator constantly displays the Cor-rected Volume by default (Fig. 3-3). To activate additionalscreens within the Display Mode, remove the blue cap from theAmerican Meter Magnetic Wand (Part No. 52797P001).

Momentarily swipe the magnetic end of the red wand past thesolid target to the right of the display (Fig. 3-2). This willactivate the second informational display screen or the Uncor-rected Volume (Fig. 3-4).

The screens will appear in sequential order as long as thewand is swiped within 15 seconds or less. If more than 15seconds elapses before the wand is swiped past the target,the display screen will return to the default Corrected Volumescreen.(Fig. 3-3)

If the display is blank, check for proper battery connection or adead battery. Refer to the Battery Replacement section of thismanual for instructions (page 3.5).

The screen will sequentially display an additional four (4)informational readings as long as the wand is swiped within 15seconds.

Swiping the wand past the target within the allotted 15 secondsor less will advance the Temperature Compensator to the thirddisplay screen, Flow Temperature (Fig. 3-5). The actualtemperature of the temperature probe located in the RPMMeter will be displayed at this time in either Fahrenheit orCelsius.

Another pass of the wand will activate the fourth screen, theprojected Remaining Battery Life (Fig. 3-6) as a percentage.This screen will also appear if a pass of the wand is initiated oneither target if the Change Battery screen (all decimals withcorrected volume (Fig. 3-18)) is active.

Passing the wand over the display within 15 seconds activatesthe fifth screen, or the Fixed Pressure, (Fig. 3-7) displayingthe value in either PSI or BAR.

To Place the Temperature Compensator unit in the DisplayTest Mode, remove the blue cap from the American MeterMagnetic Wand (Part No. 52797P001).

Momentarily swipe the magnetic end of the red wand past theopen target (Fig. 3-9) to the left of the display. This will startthe display test. Susequent passes of the wand past the opentarget to the left within a 15 second period will toggle throughthe remaining (5) five screens.

The Display Test screen (Fig. 3-10) is the first screen to beactivated. All of the digits on the screen with the exception ofthe first two will be displayed as eights. This is to assureaccurate display registration. This test screen appears for aperiod of 15 seconds then automatically reverts to the Cor-rected Volume (default display in Display Mode).

If however, the open target is swiped with the magnetic wandwithin the alotted 15 seconds, the second screen of the Dis-play Test Mode will be activated.

The second screen of the Display Test Mode is the CorrectedMultiplier screen. The third screen is the Uncorrected Multi-plier (Fig. 3-11). These screens displays the preset multiplyingfactor (x10, x100, x1000, x10,000).

Another pass of the wand will activate the fourth screen,Software Revision & Battery Type (Fig. 3-12). This screenshows the software revision number along with the type ofbattery contained in the Temperature Compensating unit. Thetwo battery types available are AL -Alkaline or LI - Lithium. Thebattery type can be set through the TC DAS software.

Another pass of the wand will activate the fifth screen, display-ing the Supercompressibility Coefficient (Fig. 3-13).

Another pass of the wand will activate the sixth screen, Bat-tery Reset (Fig. 3-14). The Battery Reset screen will firstshow the estimated percent battery life remaining of the battery

An intermittentconnector condition may exist causing temperature readings inexcess of 100oF (38o C) or less than -40oF (-40o C). When thisalarm condition occurs, the unit ceases calculation of thecorrected counts. The uncorrected counts will continue to beprocessed and stored. These readings can be obtained byactivating the solid target with the magnet. The Probe Alarmcan be reset using the TC meter reader software and a por-table computer.

Check Sum Error (Fig. 3-21). This alarm condition indicatesthe possibility of corrupted EEPROM data. When this alarmcondition occurs, contact the factory for further instructions.

Should one or more alarm condition occur at the same time,the display will show the alarm of the highest priority. The orderof priority is: 1) Low Battery, 2) Check Sum Error 3) ProbeError, and 4) Change Battery.

The RPM Temperature Compensator may be linked to remotecounters.

Connection of a cable between the optically isolated 6-pinconnector (located on the left rear of the RPM TemperatureCompensator, see figure 3-22) and the remote counters, willallow two counters to display corrected volume and onecounter to display the uncorrected volume. The pre-selectedvalues for the output pulse width and volume per output pulsecan be set at the factory if specified with the order or in the fieldusing TC DAS software.

Temperature Compensator

The Temperature Compensator stores in memory daily sum-mation data of corrected and uncorrected volume for thecurrent month in operation. In addition, a total monthly summa-tion history file is retained for the same data for the six (6)previous months (Fig. 3-24) . A complete six (6) month historyis available for access via the unit’s downloading interface portlocated on the right rear of the RPM Temperature Compensa-tor (Fig. 3-25) to an on-site portable computer or transmitter viaa customer supplied modem.

Complete operating instructions for TC data acquisition isincluded with the TC DAS Software Kits P/N 52699K001 forWindows 3.1x, and P/N 52699K002 for Windows 95/98.

The following items should be inspected during routine fieldvisitations to the meter site:

• Listen for abnormal sounds in the meter such as squeaksor grinding.

• Check all pertinent oil level sight plugs for correct volumeand black or gray oil discoloration.

• Analyze the meters general condition: look for damage tothe outer case due to vandalism, vehicles, weld burns,steam/water drippage, etc. Is there indication of excessivevibration?

• Is the meter still level within +1/16" per foot in all direction-al planes?

• Is there any deformation or strained inlet-outlet piping?

• Examine and clean all upstream strainers and filters.

• Check the rotary meter drive output for binds, i.e.,ratcheting movement, no registration.

• Check the instrument drive for binds.

• Check the temperature compensator for accuracy, digitaldisplay, battery life remaining, and low battery warnings.

• Clock the meter for passage of predetermined volume ofgas by using the dial on the register with the stop watch.

• Differential pressure test @ 20%, 50% and 80% using aaccurate test gauge.

Record all pertinent data on the maintenance record includedin the Appendix.
