Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
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
• See the Technical Specifications on page 21 for
fluid and ambient temperature limits.
• Only use the flow meter with fluids that are
compatible with the “Wetted Parts” listed in the
Technical Specifications.
Flow Volume Range
The G3000v G3000A, G250, and FX250 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).
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, G3000A, G250, and FX250: If the flow
meter scale factor is not between 0.112-0.140
cc/pulse, follow the cleaning procedure on page 13,
then recalibrate the flow meter.
G3000HR and G250HR: If the flow meter scale
factor is not between 0.05-0.07 cc/pulse, follow the
cleaning procedure on page 13, then recalibrate the
flow meter.
S3000: If the solvent meter scale factor is not
between 0.019-0.022 cc/pulse, follow the cleaning
procedure on page 13, then recalibrate the flow
meter.
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.
Do not exceed the maximum working pressure of
your meter or any component or accessory in your
system.
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.

Maintenance
12 308778ZAG
Maintenance
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.
• Check the meter routinely to develop the correct
cleaning schedule.
• Use the proper cleaning solvent for the fluid being
metered.
Flush the Equipment
Flush the fluid supply line and meter fluid reservoir daily
with a compatible solvent as instructed below.
1. Perform the Pressure Relief Procedure, page 10.
2. Connect the fluid line to the solvent supply unit.
3. Flush the meter until it is clean.
4. Perform the Pressure Relief Procedure, page 10,
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.
Improper wiring can cause fire and explosion, electric
shock, or other serious injury.
• Disconnect power source before installing.
• All electrical equipment must only be installed by a
qualified electrician.
• Understand and follow you local code and safety
regulations for hazardous location wiring of
intrinsically safe circuits.
NOTICE
Do not immerse the meter in solvent with the elec-
tronic 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.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest
possible pressure.

meter at a clean workbench. Use only lint-free cloth on
parts.
1. Follow the Pressure Relief Procedure, on page
10. Then close the fluid shut-off valve on each side
of the meter.
2. Disconnect the cable from the electronic sensor
device.
3. Disconnect both fluid line fittings and remove the
meter from the fluid line.
4. Loosen the two screws and remove the electronic
sensor device from the flow meter upper housing.
See the Parts drawing, page 18.
5. Unscrew the 8 screws (3a) from the base (3b) of the
meter.
6. Carefully remove the cover (3f). Turn it over and
remove the shims (3c).
NOTE: See FIG. 4. Two shim configurations are used.
Some meters use one 0.1 mm shim (3c) above each
gear (3d) and one below. Other meters stack three
shims (.02 and .05 mm, for a total shim height of .09
mm) above and below each gear. When replacing
shims, always maintain the configuration used on your
meter.
7. Remove the o-ring (3e). Carefully remove the
gear/bearing assemblies (3d). Remove the shims
(3c).
NOTE: Do not remove the gear shafts (S) or the gear
bearings (B).
8. Clean the meter parts with solvent. Do not use
aggressive cleaning agents. Ultrasonic cleaning is
recommended for the gear/bearing assemblies. Dry
all parts thoroughly after cleaning.
9. Place the bottom shims (3c) on the shafts (S).
Maintain the configuration used on your meter.
10. Install the gear/bearing assemblies (3d) on the
shafts. Install the top shims (3c). Maintain the
configuration used on your meter.
11. Insert the o-ring (3e) in the groove of the cover (3f).
Carefully mount the cover on the base (3b).
12. Install the screws (3a). Tighten them oppositely and
evenly, to 11 ft-lb (15 N•m). Do not over-tighten.
13. After tightening all screws, insert a plastic pick
through the meter inlet or outlet and check that the
gears can turn freely.
14. Set the electronic sensor on the cover and tighten
the two screws hand-tight, about 27-57 in-lb
(3.1-6.4 N•m). Do not over-tighten.
Installing and servicing this equipment requires
access to parts that may cause electric shock or other
serious injury if the work is not performed properly. Do
not install or service this equipment unless you are
trained and qualified.
Use only genuine Graco replacement parts.
Substitution of components may impair intrinsic
safety. This could result in a failure which causes
serious injury or substantial property damage.
