2. Warning
2.1 Explosion and Fire hazards
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous
condition and result in an explosion or fire and cause serious injury.
• Be sure the fluid system is properly grounded. See your pump instruction manual for
details.
• If there is static sparking or if you feel an electric shock while using the meter, stop
dispensing immediately. Identify and correct the problem before continuing.
• Provide fresh air ventilation. This will avoid the buildup of fumes from the fluid being
dispensed.
• Do not smoke while dispensing flammable fluids.
• Keep the dispensing area free of debris including solvents, rags and spilled gasoline.
2.2 Meter hazards
Equipment misuse can cause the meter to rupture or malfunction and cause serious
injury.
• This equipment is for professional use only.
• Read all instructions, tags and labels before operating the equipment.
• Use the equipment only for its intended purpose.
• Do NOT modify or alter the equipment.
• Do NOT leave equipment unattended while dispensing.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do NOT exceed the maximum working pressure level of the lowest rated system
component.
• Use only extensions and nozzles that are designed for use with this equipment.
• Use only fluids and solvents that are compatible with the equipment. Read all fluid
and solvent manufacturer’s warnings.
• Tighten all fluid connections before operating this equipment.
• Do NOT stop or deflect leaks with hands, body, gloves or rags.
• Do NOT dispense towards any person or any part of the body.
• Do NOT place hands or fingers over the end of or into the dispense valve.
• Comply with all local, state, and federal fire, electrical and safety regulations
• Use of this product in a manner other than specified in this manual may result in
impaired operation or damage to equipment.
This meter is designed specifically to dispense petroleum products.
Do not use for windshield wiper fluid, brake fluid, or water based solutions.

5. Meter installation
5.1 Relieve system pressure
1. Turn off the power supply to the pump or close the shutoff valve.
2. Dispense any fluid in the system into a waste container by opening the meter(s).
3. Open all bleed-type master air valves and fluid meter(s) in the system.
4. Leave the meter(s) open until ready to pressurize the system.
Pressurized equipment
This equipment stays pressurized until the pressure is manually relieved. To reduce the
risk of injury from fluid spray from the meter follow the pressure relief procedures when
you:
• Are instructed to relieve pressure
• Stop dispensing
• Check, clean or service any system equipment
• Clean or install nozzles
5.2 Grounding
1. Grounding reduces the risk of static sparking. Ground all system components
according to local, state, and federal codes. Consult the pump user's manual and
other system components to ground the following:
2. Pump: follow manufacturer's recommendations
3. Air and Fluid Hoses: use only grounded hoses
4. Air Compressor: follow manufacturers recommendations
5. Fluid Supply Container: follow the local code
Explosion and fire
Movement of fluids through the dispensing system creates static electricity. Static
electricity can cause volatile fumes resulting in an explosion and fire. The dispensing
system must be grounded.
5.3 Flushing procedure
NOTE: If the system has multiple dispense positions, begin at the position farthest from
the pump and move towards the pump.
1. Close fluid dispense valves at every position.
2. Once the main fluid outlet valve at the pump is closed and the air pressure to the
pump motor is properly adjusted, the air valve is opened.
3. Slowly open the main fluid valve.
4. Place the hose end in a waste container. Make sure hose is secure so no fluid leaks
during flushing.
5. Slowly open the dispense valve and allow enough fluid to pass through it to ensure
that the system is clean.
6. Close the valve and repeat for all dispense positions.
If this installation is new or if the fluid in the lines is contaminated, flush the system before
installing the meter(s).

Meter installation page 4/20
5.4 Apply meter to hose
Close the drain valve before starting this procedure.
1. Attach swivel to meter. Apply thread sealant to
the male end of the hose. Recommended sealant
is Loctite
®
243.
2. Insert the metal end of the hose into the swivel.
Tighten completely with an open ended,
adjustable, wrench.
NOTE: The threaded end of the meter always has
female threads. The metal end of the hose must have
male threads. Apply thread sealant, Loctite® 243 or
equivalent, to the male end. The inlet and outlet swivel
connections are either 1/2" NPT or 1/2" BSPP,
depending on meter model.
Attach the hose
5.5 Apply nozzle to meter
1. On the opposite end, apply sealant to the end of
the nozzle. Recommended sealant is Loctite
®
243.
2. Thread the nozzle onto the meter. Screw it in
tightly with an open ended, adjustable, wrench.
3. Open all dispense position shut-off valves. Start
the pump to pressurize the system.
4. Before use, to ensure accuracy, purge all air from
the fluid lines and dispense valve(s).
Attach the nozzle

2. Unscrew the two screws. Remove the battery door
to expose the batteries.
3. Replace the old batteries. The meter takes 4 AA,
alkaline, batteries.
NOTE: Battery polarity markings are inside battery
compartment.
4. Dispose of used batteries properly, according to
local regulations.
NOTE: Changing the batteries does not affect any of
the programmed values or totals.

Change factory settings page 9/20

9.3 Change scale factor
Changing the scale factor changes the accuracy of the meter, potentially causing it to
overfill or under fill. This has the potential to cause a mechanical breakdown.
1. Press the button to advance through the scale
factor digits.
2. Press the button to change the selected
number.
NOTE: All digits can be scrolled between 0 and 9 except
the first. It can only be scrolled from 0 to 1 or from 1 to 0.
3. Press the button to advance to the next number in scale factor.
4. Repeat steps 2 and 3 for all five digits in scale factor.
9.4 Save changes
To save changes and exit the programming mode:
1. Push and hold at the same time the and buttons.
2. The display will flash 3 times and go blank.
3. Press the button and the display will turn back on.
9.5 Verify changes
1. Verify unit of measure is correct.
2. Push and hold the total button and auto button together, to verify that the scale
factor is correct.
10. Calculate scale factor
A scale factor is a number used to adjust meter accuracy. The scale factor is set at the factory
using motor oil with a viscosity of 10W.
The primary use for scale factor recalibration is to batch fluids with different viscosities. If the
fluid has a lower viscosity, more fluid can slip past the meter gears without being detected.
Changing the scale factor adjusts the meter to compensate for the loss.
The meter multiplies each pulse by the scale factor number to correct the accuracy when it
converts to the specified units. The reading is then always correct.
For an approximate scale factor for fluids of different viscosities, consult the charts on page
10.
NOTE: The meter’s original scale factor was written on the trigger when it was calibrated at
the factory. It may have been revised after field installation. Use the scale factor showing on
the display, not on the trigger.
Changing the scale factor will change the accuracy of the meter, potentially causing it to
overfill or under fill. This has the potential to cause a mechanical breakdown.
To view the current scale factor:
Press and hold the button and the button at the same time.
Scale factor digits

Calculate scale factor page 11/20
10.1 Absolute scale factor
For absolute scale factor, perform this test:
1. Run a measured amount of fluid through the meter.
2. If the meter delivers 4.20 quarts and the display shows only 4.00 quarts, then the
scale factor needs to be adjusted.
3. Divide what the meter delivered (4.20) by what the display shows (4.00). You get an
error factor of (1.05).
4. The existing scale factor is 1.0123, as shown in steps 1 and 2 in “To view the
current scale factor”, above.
5. To calculate a new factor:
1.0123 (existing scale factor) x 1.05 (error factor) = 1.0629 (new scale factor).
6. Enter that number as described in change scale factor, on page 8.
NOTE: Use the scale factor showing on the display, not on the trigger.
