Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
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. Turn off the fluid supply to the meter.
2. Set the Flow Rate Percent to at least 50 percent.
3. Follow the Pressure Relief Procedure for your
fluid system dispensing device.
4. Reduce the Flow Rate Percent to 0 percent.
NOTICE
To avoid damage to the I/P transducer, always
set the Flow Rate Percent to 0 before reducing air
pressure to the system.
Fluid Regulator Operation
Follow instructions in the fluid regulator manual to set
up, flush, and adjust the fluid regulator prior to use.

Flow Meter Operation
To reduce the risk of component rupture, which
could cause injury from splashing fluid, do not
exceed the maximum working pressure of your
meter or any component or accessory in your
system.
For information on the G3000 Graco flow meter, see
manual 308778. For information on the Coriolis flow
meter, see manual 313599. Calibrate the meter as
instructed before using the meter for production.
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 gear with air or
solvent. To prolong meter life, do not use the meter
above its maximum flow rate.
Calibrate the Meter
NOTE: See Setup Screen 5 for further screen
information, if needed.
When to Calibrate
• The first time the system is operated.
• Whenever new materials are used in the system,
especially if the materials have viscosities that
differ significantly.
• As part of regular maintenance to retain meter
accuracy.
• Whenever a flow meter is serviced or replaced.
Read Before Calibration
• Meter k-factor on Setup Screen 5 is updated
automatically after the calibration procedure is
completed. You also may manually edit the
k-factor if desired.
• All values on this screen are in cc or cc/pulse,
regardless of the units set in the other Setup
screens.
• Before calibrating the meter, be sure the system
is primed with material.
• Disable alarms before calibration.
