HOW LC METERS WORK
Liquid Controls meters are positive displacement
meters. They are designed for liquid measurement inboth custody transfer and process control applications.
They can be installed in pump or gravity flow systems.
Because of their simple design, they are easy tomaintain, and easy to adapt to a variety of systems.
The meter housing (1) is designed with three cylindricalbores (2). Three rotors, the blocking rotor (3) andtwo displacement rotors (4, 5), turn in synchronized
relationship within the bores. The three rotors aresupported by bearing plates (6, 7). The ends of therotors protrude through the bearing plates. The blocking
rotor gear (8) is placed on the end of the blocking
rotor. The displacement rotor gears (9, 10) are placedon the ends of the displacement rotors. These gears
create the synchronized timed relationship between thethree rotors.
As fluid moves through the meter housing, the rotor
assembly turns. The liquid is broken into uniform
sections by the turning rotors. Fluid displacement occurs
simultaneously. As fluid enters, another portion of thefluid is being partitioned and measured. At the sametime, the fluid ahead of it is displaced out of the meterand into the discharge line. Since the volume of thebores is known, and the same amount of fluid passes
through the meter during each revolution of the blocking
rotor, the exact volume of liquid that has passed throughthe meter can be determined with a high degree of
accuracy.
This true rotary motion is transmitted through thepacking gland, the face gear, the adjuster drive shaft,and the adjuster to the register stack and counter. Truerotary motion output means consistent accuracy since
the register indication is in precise agreement with theactual volume throughput at any given instant.
At any position in the cycle, the meter body, the blocking
rotor, and at least one of the displacement rotors form
a continuous capillary seal between the unmetered
upstream product and the metered downstream product.
Because the product is separated by the capillary seal,

6   WWW.LCMETER.COM

Meter Element Exploded Line Drawing

no metal-to-metal contact is required within the metering
element. This means no wear. No wear means noincrease in slippage, and no increase in slippage meansno deterioration in accuracy.
Throughout the metering element, the mating surfaces
are either flat surfaces or cylindrical faces and sections
that are accurately machined. These relatively simple
machining operations, plus the fact that there is no
oscillating or reciprocating motion within the device,permits extremely close and consistent tolerances within
the LC meter.
The product flowing through the meter exerts a
dynamic force that is at right angles to the faces of thedisplacement rotors. The meter is designed so that therotor shafts are always in a horizontal plane. These twofacts result in no axial thrust; therefore, LC meters do
not need thrust washers or thrust bearings, the rotors
automatically seek the center of the stream between thetwo bearing plates, eliminating wear between the ends ofthe rotors and the bearing plates. Once again, no wear
results in no metal fatigue and no friction.
Liquid Controls meters are made of a variety of materials
to suit a variety of products. Because of their no-wear
design, capillary seals, and unique rotary metering, LC
meters provide unequalled accuracy, long operating life,and unusual dependability.

INSTALLATION REQUIREMENTS▪ TAKE ALL NECESSARY SAFETY PRECAUTIONS
Make sure that all necessary safety precautions have been taken.
Provide for proper ventilation, temperature control, fire prevention,
evacuation and fire management.

▪ PROVIDE ACCESS FOR FIRE EXTINGUISHERS

Provide easy access to the appropriate fire extinguishers for yourproduct. Consult with your local fire department and state and local
codes to make sure that you are adequately prepared.

▪ READ PROVIDED LITERATURE

Read this manual as well as all the literature provided in your red
Owner’s Information Packet. If you have any questions, consult
with your full-service distributor or call the Service Department at
Liquid Controls.

▪ CONFORM TO ALL CODES! WARNING
Under normal operation, do not expose any portionof the LP-Gas system to pressures in excess of rated
working pressures without an automatic safety valve tovent the over pressure discharge to a place of safety
away from the operator and other people.
Failure to provide such a safety relief
may result in leakage or rupture of one ormore of the components in the system.
This can result in injury of death from thegas, a fire, or pieces of flying debris fromthe rupture.

Install the meter and accessories in conformance with applicablestate and federal construction, electrical and safety codes.

▪ LEAVE THREAD CAPS IN PLACE

Before shipment, protective thread caps are placed in all meterand accessory openings. They should remain in place until you
are ready to attach piping.

Class 10 LPG Meters - Codes
Class 10 LPG meters must be installed in accordance with therequirements of ANSI-NFPA 58 in addition to all other state andlocal codes.

▪ FLUSH PIPING

Prior to meter installation, the entire piping system should bethoroughly flushed of all debris with a liquid that is compatible withthe construction of the meter.

▪ KEEP EXTERNAL SURFACES OF THE METER
CLEAN▪ MOUNT METER SECURELY

The meter must always be securely bolted to a platform or
supporting member, regardless of the mounting position of themeter. Never “hang” a meter on the connecting piping.

▪ PREVENT PIPE STRAIN OR STRESS

Prevent pipe strain or stress from occurring when making meter oraccessory repairs. Pipe strain and stress occurs when the pipes
are not supported or are not aligned correctly to the meter. The
weight of the pipes must always be supported independent of themeter. This means that the meter and accessories can be easily
removed without affecting the pipes or the pipe alignment. Neverleave any of the pipes hanging.

▪ INSTALL METER ONLY ON THE DISCHARGESIDE (DOWNSTREAM) OF THE SYSTEM PUMP
▪ APPLY PIPE COMPOUND TO MALE THREADSONLY▪ LEAVE SPACE FOR FUTURE MAINTENANCE▪ INSTALL A STRAINER

Install a strainer on the meter inlet to avoid damage from foreign
matter, such as weld slag, from entering the system. The strainer
must always be located on the inlet side.

▪ TAG FLOW DIRECTION

All meters are tagged identifying their direction of flow. Meters
are set with a flow direction of left to right as standard. However,when a meter is ordered, the customer can specify that the flow
be set from either direction. If the meter register counts in reverse,
the meter is reading the direction of flow in reverse. If this occurs,
the meter registration must be reset. For mechanical output
meters, see Reversing the Meter Registration on page 10. For
electrical output meters, such as meters equipped with a pulser
or an electronic register, refer to the manual of the electronic
component.

▪ USE CURRENT ENGINEERING DRAWINGS

Always request up-to-date, engineering approved, dimensional
drawings before starting any construction. Do not rely on catalog
pictures or drawings. They are for reference only. After receiving
prints, check to see that all equipment ordered is shown andthat any extra pressure taps, plugs, etc. are noted and their size
specified.

Position the meter with service in mind. Provide ample work
space. Removing covers can be difficult when work space is
not available. Always supply a platform or support for the meter
mounting.

▪ USE METER ONLY WITH SPECIFIED LIQUIDS

A meter is metallurgically designed to be physically compatible
with the type of liquid originally specified by the customer, andas indicated on the Serial Number Plate. A meter should not be
used with a liquid different from the liquid originally specified,unless the physical characteristics and pH rating are similar andthe application has been checked with LC Sales and Engineering
through your full-service distributor.

OPERATION REQUIREMENTS▪ THE METER MUST REMAIN FULL OF PRODUCTAT ALL TIMES.
An easy way to accomplish this is to put the meter assembly in theline below the piping center-line (a sumped position). This requires
adding elbows and flanges prior to installing the meter. The metershould be installed in a bypass loop, below the pipe center-line,with block valves upstream and downstream of the meter inside
the bypass loop. A block valve should be located in the main
pipeline and labeled as the bypass valve.

▪ PIPING PRESSURE RELIEF

Any portion of pipe system that might isolate or block flow should
be provided with a pressure relief to prevent damage from thermal
expansion. There are excellent benefits to this type of installation.
First, the meter is kept full. Second, this type of installation
allows the meter to be isolated for servicing and calibration while
continuing flow through the bypass valve.

▪ MAINTAIN UPSTREAM LINES

Upstream lines must be maintained full to prevent air from entering
the meter. If upstream or inlet lines are constructed in a manner
which allows reverse flow, foot valves, or back checks must be
installed.

▪ UNDERGROUND TANKS, SUBMERSIBLE PUMPS
Underground tanks that are furnished with a submersible pumpwill eliminate many problems that occur with positive displacement
pumps (suction pumps) when suction piping is incorrectly sized orwhen the lift is too great.

▪ API MANUAL OF PETROLEUM MEASUREMENTSTANDARDS
Every meter should be calibrated under actual service andinstallation conditions per the API Manual of Petroleum
Measurement Standards:

The following chapters of the API Manual of Petroleum Measurement
Standards supersedes the API standard 1101.
Chapter 4 - Proving Systems
Chapter 5 - Metering
Chapter 6 - Metering Assemblies
Chapter 11 Section 2.3 - Water Calibration of Volumetric
Provers
Chapter 12 Section 2 - Calculation of Petroleum Quantities▪ PROVIDE A MEANS OF CONVENIENTLY
DIVERTING LIQUID FOR CALIBRATIONPURPOSES

8   WWW.LCMETER.COM▪ EVALUATE PUMPING EQUIPMENT

Give careful attention to your system’s pumping equipment andpiping. Because of their influence on liquid being measured as itenters the metering assembly, systems should be made free ofconditions that cause or introduce entrained air or vapor.

▪ FOLLOW THE MANUFACTURER’SRECOMMENDATION FULLY WHEN INSTALLING
PUMPSGive particular attention to factors like: use of foot valves, pipe
size to the inlet, and conformance to net positive suction head
(NPSH) conditions when suction pumping is required. Follow
the manufacturer’s recommendations to minimize air and vapor
elimination problems.

▪ LIGHT HYDROCARBONS AND SIMILAR LIQUIDSFor liquids such as light hydrocarbons that tend to flash orvaporize easily at higher ambient temperatures, it is advantageous
to use flooded suctions and piping sized larger than the nominal
pump size.

▪ VEHICLE TANK INSTALLATIONS

On vehicle tank installations, the layout of the system’s piping
is crucial in preventing problems with split compartment
test conformance. Piping should slope away from a positive
displacement pump to prevent resurgent re-priming of the pump
due to drain back.

▪ AVOID HYDRAULIC SHOCK

Hydraulic shock is harmful to all the components of an operating
system, including the valves, the meter, and the pump. Becauseof the high precision with which they measure products, meters,in particular, must be protected against hydraulic shock. The bestprotection against hydraulic shock is to prevent it from occurring.
To prevent hydraulic shock, adjust the closing rate of the valve
until shock does not occur.

▪ AVOID THERMAL EXPANSION

Thermal expansion, like hydraulic shock, can easily damage
meters and other components in the system. When designing thesystem, include pressure relief valves in any portion or branch of
the system that might be closed off when an operating or block
valve is closed.

METER START UP AND OPERATION
Prior to meter start up, use extreme caution. Make sure that:
1.

The meter is properly secured

2.

All connections are tight3.

All valves are in the closed position

Dead Head Pressure - Pumps
Make sure that your pump can operate
against a dead head pressure. If not,consult the factory for assistance.

PLACING YOUR METER IN OPERATION

Prime the Pump First

When placing your meter in operation, the meter and system must be
Prime the pump before using it to fill thefilled slowly with liquid and be free of air prior to start-up. Extreme caresystem. Consult the pump manufacturer
must be taken to avoid damaging the meter during this time. When fillingfor proper pump priming.
the system with liquid for the first time, gravity filling is the preferred
method of filling the system with liquid. Gravity filling uses positive headpressure from product storage above the inlet port of the meter to fill the system. If necessary, systems can be filledwith the pump.
To fill the meter and system with liquid:
1.

Make sure all valves (upstream and downstream of the meter) in the system
are closed.

2.

Open the valve located at the storage tank a small amount. Provided there is
not a valve between the tank and the meter inlet, the meter’s register/counter
will start to move and then stop. If there is another valve between the tank and meter, repeat this process with each valve until
the meter is exposed to the liquid.

3.

Once you are assured that the meter has registered some volume and stopped, continue to open the tank valve until it iscompletely open.

4.

With the valve(s) open between the tank and the meter, slowly open the downstream valve until the meter’s register/counter
starts to move. Do not run the meter any faster than 25% of its rated flow during start-up. Once the product is flowing out of theend of your system, the outlet valve can be opened all the way, provided that the system is designed not to exceed the flowrate marked on the meter.

▪ NEVER OPERATE THE METER OR SYSTEM
WHEN PARTIALLY FILLED WITH LIQUID, OR
WITH POCKETS OF COMPRESSED AIR OR
VAPOR PRESENT.

If these conditions cannot be avoided, air and vapor elimination
systems may be required. If you cannot fill the meter slowly bygravity or by using a valve to throttle back the flow, consult thefactory.

▪ DO NOT OPERATE THE METER ABOVE THE
MAXIMUM PRESSURE LISTED ON THE SERIALNUMBER PLATE.
Under any and all pressure producing circumstances (for instance,
thermal expansion and hydraulic shock) the working pressuremust not exceed the maximum pressure indicated on the Serial
Number Plate.

If the valves are not manual, consult thevalve manufacturer for slow flow start-up.

▪ DO NOT OPERATE THE METER ABOVE THE
MAXIMUM FLOWRATE LISTED ON THE SERIALNUMBER PLATE
If the meter is operated at a rate greater than the maximum
recommended GPM, excessive wear and premature failure may
occur.

▪ THE METER CAN BE CALIBRATED FOR FLOWSBELOW MINIMUM RATINGS
If the flow remains constant and varies within narrow limits or if
the product is viscous, the meter can be calibrated for flows below
minimum ratings. If the meter is installed in a custody transfer
application (for financial transactions), the flow rate must fall withinflow rate range indicated on the serial number plate. A metershould never be run beyond the maximum flow rate determined forthat class meter and/or liquid measured.

! WARNING
Before disassembly of any meter or accessory component:• All internal pressures must be relieved and all liquid drained from the system inaccordance with all applicable procedures.
• Pressure must be 0 (zero) psi.
• Close all liquid and vapor lines between the meter and liquid source.
For Safety Rules, refer to local authorities and relevant NFPA Codes.
Failure to follow this warning could result in property damage, personal injury, or death fromfire and/or explosion, or other hazards that may be associated with this type of equipment.

REVERSING THE METER REGISTRATION
The direction of flow is specified by the customer when the meter is ordered. The standard direction of flow, facing thefront of the meter, from left to right. A red tag labelled “inlet”, affixed to the meter before shipment, indicates the inlet
side of the meter.
If the meter is equipped with a strainer, air eliminator, and/or valve, each component must be moved to the correctside of the meter when reversing the direction of flow. The strainer and air eliminator should always be located on theinlet side of the meter. Valves should always be located on the outlet side of the meter. Some parts of the valve may
require repositioning. See the valve’s manual for more information.
When the meter is first installed, check the register. If the register counts down, meaning that the register numbers
decrease rather than increase, you must reverse the position of the adjuster drive gear.
To reverse the drive to the register, the position of the adjuster drive gear relative to the pinion gear of the packing
gland must be flipped.
To reverse the meter registration:
1.

Remove the dust cover. See Removing the Dust Cover on page 13.

2.

Remove the retaining ring (4) with a screwdriver or pliers.

3.

Remove the two retaining spring screws (1) with a standard
screwdriver.

4.

Remove the retaining spring (2).
For M-15®, M-25®, M-30®, and M-40® models, loosen the single set screw.

5.

Remove the drive shaft (3) with the adjuster drive gear assembly
including (4) Retaining Ring and (5) Adjuster Drive Gear.

6.

Remove the adjuster drive gear (5) and turn it 180° so that it is upside
down from the original installation position. The bushing (7) supports
the adjuster drive gear in the lower position. The retaining ring (4)supports the adjuster drive gear in the upper position.

7.

Reassemble the parts in reverse order. Make sure that the adjuster
drive gear meshes with the packing gland’s pinion gear (6) without
being too tight. There should be a little play in the gear teeth. The
retaining ring (4) should be placed in the groove provided on the drive
shaft (3), regardless of the adjuster drive gear position. The packing
gland pinion gear to adjuster drive gear ratio is either 1:1 or 2:1. In the
2:1 ratio, the pinion of the packing gland is smaller in diameter.

SETTING THE STANDARD ADJUSTER
To set the standard adjuster:1.

Remove the dust cover. See Removing the Dust Cover on
page 13.

2.

Check meter registration by delivering product to a reliable,
accurate prover. Perform multiple delivery tests to verify themeter repeatability.

3.

Record the setting indicated on the adjuster:

4.

Note the difference between the volume of the prover and the volume indicated on the meter counter. 			
Calculate the % correction required using the formula below.

Mechanical Instructions Only
These instructions apply to meters equipped with mechanicaloutput accessories only. If your meter is equipped with anelectrical output (i.e., electronic pulser), refer to the manual
for the electrical component your Owner’s Information Packet.

Volume in prover - Volume on meter counter% Correction =					x
100Volume in prover

5.

Loosen the adjuster clamp screw.

6.

When the prover volume is less than the meter counter volume, add the percentage to the original adjuster setting by turning
the thimble towards the arrow marked larger (volume). Correct the original setting by approaching the number desired from thenext larger number. For example, if the desired adjuster setting is 2.4, turn the adjuster thimble to the left to number 5, then to
the right to obtain the 2.4 setting. Adjuster is currently set at 2.3 in the illustration below.

7.

When the prover volume is more than the meter counter volume, subtract the percentage from the original adjuster setting by
turning the thimble in the direction of the arrow marked smaller volume percent.

8.

Retighten the adjuster clamp screw. Run product through the meter to allow the adjuster to take a set. Then make several
prover runs to check for accuracy

• Close all liquid and vapor lines between the meter and liquid source.
For Safety Rules, refer to local authorities and relevant NFPA Codes.
Failure to follow this warning could result in property damage, personal injury, or death fromfire and/or explosion, or other hazards that may be associated with this type of equipment.

▪ PREVENT PIPE STRAIN OR STRESS

Prevent pipe strain or stress from occurring when making meter oraccessory repairs. Pipe strain and stress occurs when the pipes
are not supported or are not aligned correctly to the meter. The
weight of the pipes must always be supported independent of themeter. This means that the meter and accessories can be easily
removed without affecting the pipes or the pipe alignment. Neverleave any of the pipes hanging.

▪ SEASONAL METER STORAGE

If the meter is used for seasonal work, the meter should
be removed from the system and thoroughly flushed with acompatible liquid at the end of each season. To flush the meter,
remove the drain plug on the front and rear covers. Then flush the
product from the front and rear covers. If flushing with water, extra
care should be taken to drain the meter completely and dry allinternal parts. Refill the meter immediately with a compatible liquid(or oil misting). Refilling is essential to preventing corrosion andice damage that can result from any moisture that was overlooked
after flushing and drying.

▪ DO NOT MAR OR SCRATCH

Do not mar or scratch any of the precision machined surfaces byprying or sanding parts.

▪ TORQUE ALL FASTENERS

Torque all fasteners such as screws and bolts in accordance withspecifications listed in the Torque Chart on page 21.

▪ STONE THE MACHINED SURFACES

Stone the machined surfaces when reassembling the meter toassure that the machined surfaces are free of burrs and mars.

▪ EXAMINE ALL FASTENERS

Examine all fasteners to make sure they are not bent, rusted, or
have pulled threads. The threads should all appear evenly placed.
If the bolts are bent, check the housing and cover for flatness. Usea straight edge to determine flatness.

▪ LOOK FOR GAPS

Look for gaps when disassembling a meter. Use a feeler gauge
to check for gaps between the bearing plate and housing. If you
do find gaps, check the bearing plates for flatness with a straightedge. Gaps can be caused by shock problems. If shock problems
exist, they must be resolved. Contact your full-service distributor
for assistance if this occurs.

▪ CHECK THE O-RINGS

Check the O-rings for damage. Cracked, rough, or worn O-rings
should be replaced. However, a more serious problem of shock
may be indicated if the O-rings look nibbled. Shock problems must
be verified and resolved. Contact your full-service distributor forassistance if this occurs.

▪ CHECK THE BEARING PLATESCheck the bearing plates for flatness. Use a straight edge.
Warped bearing plates can be caused by shock problems. If shockproblems exist, they must be resolved. Contact your full-service
distributor for assistance if this occurs.

▪ CHECK WITH REGULATORY AGENCY

Check with regulatory agency that governs Weights & Measuresin your area. Removing the dust cover seal wire or othermaintenance procedures may require Weights & Measuresrecalibration.

▪ REPAIR PULLED THREADS

Repair pulled threads with threaded insert fasteners. These canbe used in many instances. Contact your full-service distributor foradvice if this occurs.

▪ COAT THREADS WITH ANTI-SEIZE

Coat threads with anti-seize when removing and replacing bolts
and castings in the meter.

▪ REMOVING FLANGE GASKETS

Remove flange gaskets when removing the flange assembly,
always carefully scrape off the flange gaskets. Make sure that theflange surface has been scraped clean. Discard the old flange
gasket and install a new flange gasket. Never reuse old flange
gaskets.

REASSEMBLING THE METER
Reassembling the Meter
To reassemble the bearing plates and rotors:
continued from following page4.

The rotors should have a small amount of end-play andbe easy to turn. Test each rotor, one at a time. Turn therotors to make sure that they revolve freely. Jog the rotors
from end to end to check for end-play. If they do not moveeasily in both tests, remove the rotors and check forburrs and corrosion deposits. Clean them thoroughly andrepeat steps 2, 3 and 4.

5.

Each rotor has a notch, or “keyway”, to hold a rotor key.
The rotor key is a small wedge of metal. Press a rotor
key into the keyway of each rotor with your thumb andforefinger.

Rotor Keys

TIMING THE ROTOR GEARS

Before putting the meter into service, the rotors must be timed. Rotors are timed by lining up timing marks stamped
onto the face of the gears. The timing mark on the blocking rotor gear is stamped on a gear tooth. The timing mark on
the displacement rotor gears is stamped on a space between two gear teeth. You may need to remove the gears andreposition them several times to line up the timing marks correctly.
To time the rotor gears:

Torque the Gear Screw

1.

Slide the blocking rotor gear over the tapered blocking
rotor end and turn it until the timing mark is in position
to line up with the timing mark on the right displacement
rotor gear. Slide the right displacement rotor gear over
the tapered end of the rotor so that the timing mark lines
up with the blocking rotor gear timing mark.

2.

Turn the blocking rotor gear (turn the right displacement
rotor gear with it) until the timing mark is in position toline up with the timing mark on the left displacement
rotor gear. Slide the left displacement rotor gear over thetapered end of the rotor so that the timing mark lines up
with the blocking rotor gear timing mark.

3.

Position the spare displacement rotor gear between
the left displacement rotor gear and the blocking rotor
gear to prevent the gears from moving. Attach the rightdisplacement gear washer and screw using the rotor gear
wrench.

4.

Keep the spare displacement rotor gear positioned by theleft displacement rotor gear. Attach the left displacement
gear washer and screw using the rotor gear wrench.

5.

Position the spare displacement rotor gear between theright displacement rotor gear and the blocking rotor gear.
Attach the blocking rotor gear with the packing gland
driver and screw using the rotor gear wrench.

6.

Rotate the gears to make sure that the rotors turn freely.
Burrs, foreign material, or marred surfaces can restrict therotor movements. If the rotors do not turn freely, remove
the gears and rotors and deburr and clean the surfaces
again.

Tighten the gear screws to the torque specification
listed in the Torque Chart on page 22.

TROUBLESHOOTINGPROBLEMPROBABLE CAUSE & SOLUTION
Internal seal of packing gland assembly is worn. Replace packing gland and O-ring
seal.
OPERATING NOTE
Two common causes of packing gland leakage are thermal expansion and hydraulicshock.
Thermal expansion can occur when two valves in a piping system, on either side of themeter, are closed at the same time and the temperature in the system rises. As little as
a 1°F increase in temperature can drive the system pressure to a point that exceeds
the maxiumum working pressure rating of the meter. To avoid any damage caused bythermal expansion, a pressure-relief valve of some kind must be installed in the system.

Leakage past packing gland
drive shaft housing frominternal metering chamber

Hydraulic shock occurs when a large volume (mass) of liquid is flowing through thesystem and a valve suddenly closes. When the flow is stopped, the entire mass of theliquid in the piping system rams into the components within the meter. The greater thelength of line (more line length equals more liquid mass) and the greater the velocityof the liquid, the greater the hydraulic shock. Since the valve is usually located at themeter outlet, the meter housing, packing gland and the meter internal are subject to thefull impact of such hydraulic shock. To prevent hydraulic shock, a slow closing two-stage
valve should be used with the meter. On systems where mass length of line and velocity
are of a magnitude that preclude the elimination of hydraulic shock with the use of a
two-stage slow closing valve, an impact-absorbing air cushioning device can be added
to further dampen hydraulic shock.

Gasket has been damaged due to shock pressure or cover bolts have not beentightened sufficiently. Replace gasket and tighten cover bolts correctly.

A.

Check packing gland, and gear train.

B.

If all meter parts are moving then problem is in register. Faulty register should bechecked and repaired by trained mechanic.

C.

Remove register from meter. If all meter parts are moving but output shaft of adjuster
assembly is not, adjuster is worn and must be replaced.

D.

If totalizer numerals (small numbers) on register are recording, but the big numerals are
not moving, register needs repair.

E.

Packing gland gear not turning. Replace the packing gland. This may be caused bystarting the flow too rapidly.
For M-60® and M-80® meters, the drive blade may be sheared.

A.

Starting or stopping flow in meter too rapidly.

B.
