Operation
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
•
See the
Technical Data
on page 22 for fluid and
ambient temperature limits.
•
Only use the flow meter with fluids that are compati-
ble with the “Wetted Parts” listed in the
Technical
Data
.
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).
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, and G250:
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 fac-
tor 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 Pro-
cedure 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.
