Installation

Pre-Installation Procedure

1.Relieve the system pressure:

a. Turn off the power supply to the pump or close the

shutoff valve.

b. Dispense any fluid in the system into a waste

container by opening the dispense valve.

c. Open all bleed-type master air valves and fluid

drain valves in the system.

d. Leave the drain valve open until ready to

pressurize the system.

2.Close the shutoff valve.

3.Ground hoses and reels:

Grounding reduces the risk of static sparking;

ground all system components according to local,

state, and federal code. Consult the user's manual

of the pump and other system components to

ground the following:

i. Pump: follow manufacturer's recommendations

ii. Air and Fluid Hoses: use only grounded hoses

iii. Air Compressor: follow manufacturers

recommendations

iv. Fluid Supply Container: Follow the local code

Do not use Teflon®tape on pipe joints; it may cause a

loss of grounding across the joint.

Installation Procedure

1. If this is an existing installation, go directly to step 6.

Steps 2 through 5 are for flushing the system prior to

installing the meter.

2. Close fluid dispense valves at every dispense position.

3. Once the main fluid outlet valve at the pump is

closed, the air pressure to the pump motor is

properly adjusted, and the air valve is open, slowly

open the main fluid valve.

4. Place the hose end in a waste container. Make sure

hose is secure so no fluid will leak during flushing.

5. Slowly open the dispense valve and allow enough oil

to pass through to ensure that the system is clean.

Close the valve and repeat for all dispense positions.

Note: If the system has multiple dispense positions,

begin at the position farthest from the pump, and

move towards the pump.

6. Relieve the Pressure (see Relieve the System

Pressure, above).

7. Insert the metal end of the hose into the swivel

located at the end of the handle, and tighten

completely with an open ended, adjustable wrench.

Attaching the hose

Note: The threaded end of the meter will always have

female threads, so the metal end of the hose must

have male threads. Apply thread sealant to the male

end. The inlet and outlet connections are both 1/2"

NPT or 1/2" BSPP depending on meter model.

8. Thread the new nozzle onto the opposite end of the

meter and screw in tightly with an open ended,

adjustable wrench.

Installing the nozzle

9. Open all dispense position shut-off valves, and start

the pump to pressurize the system.

10. To ensure accuracy, purge all air from the fluid lines

and dispense valve before use.

Service

Changing the Battery

When the batteries need to be changed, a progression of

warnings will appear on the screen.

1.First warning: the Low Battery Icon will appear in the

lower left corner of the display. This means that the

batteries are low and need to be changed within one

week after the icon first appeared.

.QT

2.Second warning: The AUTO function will shut off and

the auto icon will disappear. This means the battery

power is too low to run the auto function. The meter

can still run in manual mode.

3.Third Warning: The screen goes blank. This means

there is no power left. The display cannot be run.

However the meter will still allow fluid to pass through

when the valve is opened, but it will not measure flow.

•The battery compartment is located on the underside of

the trigger guard. Unscrew the two screws located under

the guard and remove the battery cover to expose the

batteries.

•Replace the old batteries. This meter takes 4 AAA

alkaline batteries. Replace the cover and the screws

when finished. Note battery polarity markings inside

battery compartment cover.

•Dispose of used batteries properly according to local

regulations.

Make sure to securely replace the rubber o-rings

surrounding the battery cap and screws to prevent liquid

from leaking into the battery compartment. The o-rings are

reusable indefinately, however new o-rings can be

purchased. See spare parts drawing on page 10.

Changing the batteries will not affect any of the

programmed values, history, or totals.

button to return to the normal operating screen.

Recalibrating the Meter

The Scale factor is used to adjust the accuracy of the

meter. Thescalefactorwillbesetatthefactoryforoil.The

primary use for the recalibration function is if the user

wants to batch fluids with a viscosity other than 10W oil.

If the fluid has a lower viscosity, more fluid can slip past

the gears without being detected. Changing the scale

factor can adjust the meter to compensate for that loss

The meter multiplies each pulse by this number to correct

theaccuracywhenitconvertstothespecifiedunits,sothe

reading on the dial is always correct.

For an approximate scale factor for fluids of different

viscosities, consult the following chart:

Type of Fluid Viscosity (cp) Scale Factor

Water/Anti-Freeze 5 0.9580

Anti-Freeze 18 0.9930

Automatic Transmission Fluid 80 0.9980

Motor Oil 140 0.9960

Benz 80W-90 400 1.0020

Mobil 80W-90 450 1.0004

SAW 50W 900 1.0040

140WT 1800 1.0070

(Unless otherwise specified at the time of the order, each

meter is programmed in quarts for use with motor oil.)

Note: The original meter scale factor is written inside of

themeterwhencalibratedatthefactory. Itmayhavebeen

revised after field installation. Use scale factor shown on

display, not the lavel.

Toviewthecurrentprogramscalefactor,dothefollowing:

1. Press and hold the button.

2. Then, press and hold the button.

For an absolute scale factor, perform the following test:

Run a pre-measured batch of fluid through the meter. If the

meter is programmed to batch 4.200 quarts, and it batches

theentireamountbutonlyreads4.000quarts,thenthescale

factorneeds t beadjusted. Divide thequantitydelivers (4.2)

by the quantity dispensed (4.0) to get the error factor (1.05)

To calculate the new scale factor:

If existing scale factor is 1.0123, then calculation would be:

1.0123 (existing scale factor) x 1.05 (error factor) = 1.0629

(new scale factor)

Change the scale factor:
