GENERAL INFORMATION
The electronic digital flow meter is designed to provide precise metering
of motor oils (S.A.E. 5 - 50), gear oils (S.A.E. 80 - 240), automatic trans-
mission fluid, antifreeze solution and hydraulic fluid. The meter is not de-
signed to dispense brake fluid or windshield wiper fluid.
This meter uses oval gears, which respond to flow, and rotate dividing
the fluid into single volumes (units). As the gears rotate, they generate a
signal, via a magnetic coupling, which protects the micro-processor from
exposure to the fluid. The micro-processor uses a calibration “factor”
and calculates pulses generated by the gear rotations into calibrated
flow units which display in either quarts or liters on the meter register
(batch total).
Each meter is preprogrammed and calibrated at the factory. Unless
otherwise specified at the time of the order, each meter is programmed
in quarts for use with motor oil. The meter is shipped in the “manual”
mode. If you need to change the factory settings, see page 4.
The meter display panel has seven push-buttons (see figure 2):
Keypad Buttons “10”, “1”, “0.1” - Used to enter the quantity to be dis-
pensed.
“Total” - Used to display the accumulated total of fluid, as well as the
resettable total during “auto” and “manual” modes.
“Auto” - Used to enter and exit the “auto” mode.
“Reset” - Used in “manual” or “auto” modes to clear the previously pro-
grammed batch and to reset the meter. Used to reset the resettable
total after pressing the “TOTAL” button.
“Shut-Off” - Used to stop the flow thru a mechanical override.
Figure 2
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 open-
ing 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 thesystem.
2. Close the shutoff valve.
3. Ground hoses and reels. Grounding reduces the risk of static spark-
ing. Ground all system components according to local, state and
federal codes. Consult the user’s manual of the pump and other sys-
tem components to ground the following:
a. Pump - Follow the manufacturer’s recommendations.
b. Air and fluid hoses - Use only grounded hoses.
c. Air compressor - Follow the manufacturer’s recommendations.
d. Fluid supply container - Follow the local code.
WARNING Do not use TeflonRtape 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 thru 5
are for flushing the system prior to installing the meter.
2. Close the fluid dispense valves at every dispense position.
3. Once the main fluid outlet valve at the pump is closed, the air pres-
sure 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 the hose is se-
cure so no fluid will leak during flushing.
5. Slowly open the dispense valve and allow enough oil to pass thru to
ensure that the system is clean. Close the valve and repeat for all
dispense positions. NOTE: If the system has multiple dispense posi-
tions, begin at the position farthest from the pump and move toward
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 using an open ended, adjustable
wrench (see figure 3).

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 seal-
ant to the male end. The inlet and outlet connections are both 1/2 N.P.T..
8. Thread the new nozzle onto the opposite end of the meter and screw
in tightly using an open ended, adjustable wrench (see figure 4).
Figure 4
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.

3. Pull the trigger to begin the flow. The valve will automatically lock in
place, even though the trigger will fall back to the closed position.
The flow will automatically shut off when the desired batch size has
been dispensed.
NOTE: The meter will automatically shut off if the trigger is pulled and the
meter does not sense any flow. The display will then begin to flash, indi-
cating the meter has shut off. Press the “RESET” button to stop the dis-
play from flashing.
Also, in case of an emergency or to interrupt a batch, the meter is
equipped with a mechanical override (see “Mechanical Override”).
CAUTION The valve will always lock in the maximum open
position.
4. The user has the option to top off at the end of the batch. To top off
the tank, simply pull the trigger to begin the flow and release when
the desired amount has been pumped.
5. Press the “RESET” button when finished to reset the meter. It is now
ready for the next batch.
CAUTION Do not press the “RESET” button before topping
off. The meter will begin a new batch.
NORMAL OPERATING MODE FUNCTIONS
Total
This option allows users to see the accumulated total as well as the re-
settable total.
Press and hold the “TOTAL” button while in the normal operating mode
to see the accumulated total. Continue holding, and after 3 seconds, the
screen will change to the resettable total, which displays the total fluid
dispensed since the resettable total was last set back to zero.
Press the “RESET” button while viewing the resettable total to set the
resettable total back to zero. Release the “TOTAL” button to return to the
normal operating screen.
NOTE: The accumulated total cannot be reset unless the user changes
from English units to metric units or from metric units to English units
(see “Changing Factory Settings”).
Total Function Figure 8
Mechanical Override
In case of an emergency or to interrupt a batch, the meter is equipped
with a mechanical override. This option automatically closes the valve in
the meter, stopping the flow immediately. The display will begin to flash
because the meter does not sense any flow. Batching can be continued
after an override, even if the meter is in the middle of a programmed
batch and the display continues to flash.
Press the red “Shut-Off” button to activate the mechanical override. This
button may require considerable force to activate and can only be used
when the valve is open. Press the “RESET” button to cue up the next

batch and stop the display from flashing.
SERVICE
Changing the Batteries
When the batteries need to be changed, a progression of warnings will
appear on the screen.
1. The 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.
Figure 9
2. The 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. The 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 thru when the valve is opened, but it will not mea-
sure flow.
SThe battery compartment is located on the underside of the trigger
guard. Unscrew the two screws located under the guard andremove
the battery cover to expose the batteries.
SReplace the old batteries. This meter takes four “AAA” alkaline bat-
teries. Replace the cover and the screws when finished. Note the
battery polarity markings inside the battery compartment cover.
SDispose of used batteries properly according to local regulations.
NOTE: Changing the batteries will not affect any of the programmedval-
ues or totals.
CHANGING FACTORY SETTINGS
Factory Settings
Each meter is preprogrammed and calibrated at the factory. Unless
otherwise specified at the time of the order, each meter is programmed
in quarts for use with motor oil.
1. Press “RESET” to wake up the meter if screen is blank. To enter the

After the screen flashes, it will display the scale factor and units of mea-
surement.
Initial Programming Screen Figure 11
Programming the Units
This meter comes with the option to choose four different units of mea-
sure. Unless otherwise specified at the time of the order, each meter is
programmed in quarts, for use with motor oil. The “QT” will be flashing on
initial start-up.
1. Toggle the four options (“L”, “QT”, “GAL”, “PT”) by pressing the “TO-
TAL” button.
2. When the desired option is on the screen, press the “RESET” button
to advance. The units of measurement icon will stop flashing and the
first digit of the scale factor will begin flashing.
NOTE: If the “L” units have been selected, the decimal point will begin to
flash. The user now has the option to change the decimal point to eithera
period or a comma. To do this, press the “TOTAL” button. Press the “RE-
SET” button to advance to the scale factor screen.
CAUTION Changing the units of measurement from metric
units to English units, or from English units to metric units, will
clear the accumulated total and resettable total.
Recalibrating the Meter
The scale factor is used to adjust the accuracy of the meter. The scale
factor will be set at the factory, using oil with the viscosity of 10W motor
oil. The primary use for the recalibration function is if the user wants to
batch fluids with a different viscosity. 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 the accuracy when it con-
verts to the specified units, so the 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 (cSt) Scale Factor
Water / Anti-Freeze 5 1.044
Anti-Freeze 18 1.007
Automatic Transmission Fluid 80 1.002
Motor Oil 140 1.000
Mobil 80W-90 450 0.999
50W 900 0.996
140W 1800 0.993
Unless otherwise specified at the time of the order, each meter is pro-
grammed in quarts for use with 10W motor oil.
NOTE: The original meter scale factor is written on the inside of the me-
ter when calibrated at the factory. It may have been revised after field
installation. Use the scale factor shown on the display, not the trigger.
To view the current program scale factor, do the following:
1. Press and hold the “TOTAL” button.
2. Press and hold the “AUTO” button.
For an absolute scale factor, perform the following test:
Run a measured amount of fluid thru the meter. If the meter delivers 4.20
quarts and the display shows only 4.00 quarts, then the scale factor
needs to be adjusted. Divide what the meter delivered (4.20) by what the
display shows (4.00) to get the error factor (1.05).
Calculating the New Scale Factor
If the existing scale factor is 1.0123, then the calculation would be:
1.0123 (existing scale factor) x 1.05 (error factor) = 1.0629 (new scale
factor).
Change the Scale Factor
Press “PROGRAMMING” key to enter the programming mode, then
press the “RESET” button to advance thru the units mode.

1. The first digit of the scale factor will be flashing.
2. Press the “TOTAL” button to scroll thru the numbers.
Scale Factor Screen Figure 12
3. Press the “RESET” button to advance to the next number in the
scale factor.
4. Repeat steps 2 and 3 for all five digits in the scale factor. NOTE: All
digits can be scrolled between 0 and 9, except the first, which can
only be scrolled from 0 to 1.
5. When finished setting the scale factor, press the “RESET” button
and the scale factor and units measurement screen will be replaced
with the pulse delay screen.
Setting the Pulse Delay Factor
The pulse delay factor is used to correct for fast flow rates by closing the
valve in the meter between one and five pulses sooner than the selected
value. The meter is factory programmed with a pulse delay factor of 0.
Pulse Delay Screen Figure 13
Advance thru the unit selection and all five scale factor digits bypressing
the “RESET” button. The above screen (see figure 13) will now be dis-
played.
1. The “PS-” will be followed by a flashing zero. The zero is the initial
setting of the pulse delay factor.
2. Scroll between settings (0 - 5) by pressing the “TOTAL” button.
3. When finished selecting the pulse delay factor, press the “RESET”
button and the display will return to the scale factor screen.
4. When finished programming these options, press the “PROGRAM-
MING” key and hold it until the screen flashes three times then goes
blank. Press the “RESET” button to return to the normal operating
screen.
