Pressure Relief Procedure
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning,
checking, or servicing the equipment.
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.
Flow Volume Range
The G3000v G3000A, 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
0.01-0.42 gpm (38-1600 cc/min).
NOTICE
The flow meter gears and bearings can be damaged
if they rotate at excessive speeds. To avoid high
speed rotation, open the fluid valve gradually. Do not
over-speed the meter with air or fluid. Do not use
compressed air to rotate flow meter gears. 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.

Flushing
• Disconnect power source before installing.
• All electrical equipment must only be installed by
a qualified electrician.
• Understand and follow your local code and safety
regulations for hazardous location wiring of intrinsically safe circuits.
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.
Flush the fluid supply line and meter fluid reservoir daily
with a compatible solvent as instructed below.
1. Follow the Pressure Relief Procedure, on page 10.
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 disconnect 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.
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.
• Check the meter routinely to develop the correct
cleaning schedule.
• Use the proper cleaning solvent for the fluid being
metered.
