Pressure Relief Procedure
1. Shut off the fluid supply to the meter.
2. Shut off all electrical power to the fluid system.
3. Follow the Pressure Relief Procedure for your fluid
system dispensing device.
Flow Meter Function
This is a positive displacement, gear flow meter. The
gear flow meter is highly accurate, even with low flow
rates. The fluid flowing through the meter rotates the
gears. The gear tooth is picked up by a sensor device,
which produces an impulse for every gear tooth passing
by.
Recommended Usage
Flow Volume Range
The G3000 and G250 meters flow volume range is
0.02-1.0 gal./min. (75-3800 cc/min.).
The G3000HR and G250HR meters flow volume range
is 0.01-0.5 gal./min. (38-1900 cc/min.).
The S3000 solvent meter flow volume range is 0.01-0.5
gpm (38-1900 cc/min).
NOTICE
The flow meter gears and bearings can be damaged
if they rotate at too high a speed. To avoid high speed
rotation, open the fluid valve gradually. Do not
over-speed the meter with air or solvent. To prolong
meter life, do not exceed the meter’s maximum flow
rate.
Checking the Meter Accuracy
1. To check the accuracy of the meter, turn your gun
fan and atomizing air off, then trigger the fluid into a
graduated cylinder; dispense at least 500 cc of fluid.
2. Measure the volume of fluid in the beaker in
cubic-centimeters (cc) and read the volume on the
flow meter monitor.
G3000 and G250: If the flow meter scale factor is
Do not exceed the maximum working pressure of your
meter or any component or accessory in your system.
• See the Technical Data for fluid and ambient tem-
perature limits.
• Only use the flow meter with fluids that are compati-
ble with the “Wetted Parts” listed in the Technical
Data.

Maintenance
If the meter is not installed in an instrinsically safe
location, make sure the power is off or the electronic
sensor is disconnected before wiping the outside of
the meter clean with a cloth dampened in a compatible solvent or flushing the meter.
Maintenance
Flushing
Flush the fluid supply line and meter fluid reservoir daily
with a compatible solvent as instructed below.
NOTICE
Do not immerse the meter in solvent with the electronic sensor installed. Solvent could damage the
electrical components.
Air purge is not recommended for any gear-type flow
meter. Air purges do not provide the lubrication the
meter gears require.
Residue Build-up on the Meter Gears
Residue build-up may cause the meter gears to bind or
stop rotating, which decreases the meter accuracy and
makes meter recalibration necessary. As more build-up
occurs, recalibration is required more often.
The frequency that your meter requires cleaning
depends on the type of fluid being used. Excessive residue build-up usually means that you are using improper
cleaning solvents and/or cleaning sequences or processes.
1. Follow the Pressure Relief Procedure, on page 7.
2. Connect the fluid line to the solvent supply unit.
3. Flush the meter until it is clean.
4. Follow the Pressure Relief Procedure, then dis-
connect the fluid line from the solvent supply unit.
5. Reconnect the fluid line to the fluid (paint) supply.
6. Turn on the fluid supply.
7. Operate until the meter and fluid line are free of solvent.
• Check the meter routinely to develop the correct
cleaning schedule.
• Use the proper cleaning solvent for the fluid being
metered.
