Upon receipt of your meter, examine it
to make sure there are no visible signs
of damage. If damage is evident, please
contact your GPI distributor.

inlet and outlet ports.
2. Wrap threaded male connections
with oil resistant thread tape or use
apipe sealantcompound compatible
with fluids being dispensed.
3. Install the meter on the pump. The
meter’s outlet port is marked with a
flow arrow.
4. Install other system components on
the meter and tighten snugly.
Meter Accuracy
Thismeterisfactory calibratedtohydraulic
oil with accuracy of ±2%. Due to differ-
ences in viscosities andflowrates, calibra-
tion may need to be adjusted if other fluids
are being dispensed. Refer to the Repair
Section for calibration instructions.
1. Before use, visually check the meter
to ensure it is securely fitted to other
system components and there is no
leakage at connections. If leakage is
present, refer to the Troubleshooting
Section.
2. Follow safety precautions, wiping
any spilled fluid from the exterior of
the meter and other system compo-
nents.
INSTALLATION
OPERATION
Totalization
1. The large display on the meter rep-
resents the Batch Total for each fluid
delivery. Beforemeasuringfluid,reset
the Batch Total to zero by turning the
reset knob on the side of the meter
counterclockwise.
NOTE: The small display represents the
Cumulative Total measured and can-
not be reset.
2. Toenhancemeteraccuracy,dispense
fluid using a quick-open and quick-
close method. Avoid choking flow as
the tank becomes full.
Your mechanical lube meter is designed
for minimum maintenance. Examine the
meter and other system components
regularly for leakage. Keep the system
exterior clean to help identify leaks.
The LM-200 meter is equipped with an
internal strainer. The strainer should be
checked periodicallyorwhenever lowflow
is noticed. The meter may also require
recalibration if actual fluid delivery differs
noticeably from meter readings. Refer to
the Repair Section for strainer access and
calibration information.
Clean Strainer
1. Remove the four retaining screws on
the strainer coverplate. Remove the
coverplate and strainer.
2. Using a fine brush, clean the strainer
and reposition in the housing.
3. Wipe clean the strainer coverplate
O-ring,groove,and thehousing.Coat
the O-ring with oil or light grease and
install in the coverplate groove.
4. Hold the coverplate in position and
replace thefourscrewsbyalternately
tighteningscrewsuntil the coverplate
is firm against the meter housing.
MAINTENANCE

1. Purge air from the meter and system
by dispensing fluid into a container
until a full flow occurs. Close the
nozzle.
2. Reset the meter counter to zero by
turning the reset knob counterclock-
wise.
3. Fill a graduated calibration container
to a specified quantity. For the great-
est accuracy, be sure the container
is placed on a level surface and a
consistent flowrate is used. When
topping off the calibration container,
use a quick-open and quick-close
method until the mark is reached.
NOTE: Your GPI dealer can supply a
calibration container designed for
this purpose.
4. Compare the meter display to the
quantity in the container. If the dis-
play does not register the quantity
on the container, adjust the meter
by performing the following:

bration screw by removing the
calibration screw cover.
b. If the meter registered less than
the quantity in the container, turn
the calibrationscrewclockwise. If
the meter display read more than
the amount in the container, turn
the screw counterclockwise.

sary. Make sure the nutator disc pin
is secure in the back of the counter
assembly before assembling again.

the meter connections from other
system components by hand. Do not
