Quick Start
If your installation is relatively simple
and you have installed our Electronic
Digital Meter (EDM) meters before,
you may use this section to quickly
install and operate your meter. This
section is especially helpful to those
measuring thin vis cosity uids dis-
pensed through a hose and nozzle.
If you complete this section and
encounter di󰀩culties, please refer to
other sections, as necessary.
NOTE: To accommodate di󰀨erent
installations, the faceplate can be
rotated 180 degrees. To do this,
remove the four corner screws
from the face of the meter and lift
the computer assembly from the
turbine. Rotate the computer as-
sembly 180 degrees. Place on the
turbine ensuring the seal is fully
seated. Secure the four screws.
Connections
1. To protect against leakage, make
sure all threads are sealed with
two or three turns of thread tape
or a sealing compound compat-
ible with the liquid being metered.
(Figure 1)
2. Make sure the arrow on the outlet
is pointing in the direction of the
ow. (Figure 2)
Make sure the thread tape or
sealing compound does not
interfere with ow.
CAUTION
3. Tighten the meter onto the ttings.
Use a wrench only on metal me-
ters. Hand tighten plastic meters.
Using a wrench on plastic me-
ters could damage the meter.
CAUTION
Verify Meter Accuracy
Before using, you should check the
meter’s accu racy and verify calibra-
tion.
1. Make sure there is no air in the
system by starting the ow until it
runs steadily. Then, stop the ow
using a valve or nozzle.
2. If desired, hold down DISPLAY
for 3 seconds to zero the meter’s
Batch Total. When zeros appear,
release the button.
3. Verify meter accuracy before
use. To do this, measure a
known quantity of liquid into a
calibration container and compare
the volume measured against
the readout. If necessary, eld
calibrate the meter. Refer to the
Calibration Section.

Review the Before Installation and
Quick Start Sections. Also consider
the following recommendations, es-
pecially if you are installing your meter
in a piping system. These suggestions
will help maximize performance of
your meter.
The meter can be mounted either
vertically or horizontally. It should be
eld calibrated in the same orientation
in which it is mounted.
Avoid installing the meter in electri-
cally “noisy” environments. If installed
within 6 inches (15.2 cm) of large mo-
tors, relays, vehicle ignition systems,
or transformers, the meter’s accuracy
can be adversely a󰀨ected.
To avoid pulsation or swirl, use the
following recommendations.
For Low Flow or one inch meters,
install with
– 20 inches (51 cm) of straight
pipe upstream and
– 5 inches (13 cm) of straight
pipe downstream.
For two inch meters, install with
– 40 inches (102 cm) of straight
pipe upstream and
– 10 inches (26 cm) of straight
pipe downstream.
Flow straightening vanes installed
upstream from the meter can reduce
the upstream pipe length.
Flow control valves upstream from
the meter and within the straight pipe
distances given earlier can adversely
e󰀨ect meter accuracy. This is espe-
cially true when measuring liquids
with low vapor pressures such as
fuels, oils and solvents.
If cavitation e󰀨ects meter accuracy, a
ow control valve on the downstream
side of the meter can provide a back
pressure of 5 to 50 PSI (0.3 to 3.4
bar) to minimize the problem.
4. To ensure accurate measure-
ment, remove all air from the
system before use. To purge the
system of air:
a. Open the discharge valve or
nozzle and allow uid to com-
pletely ll the system. Make
sure the stream is full and
steady and no air is present.
b. Close the discharge valve or
nozzle. Leave the system on.
c. Start normal operations. If nec-
essary, zero the Batch Total.
Using the Meter
The meter display is on continually
and always ready for use.
To determine the exact volume mea-
sured with each use, use the Batch
Total function. You can zero the Batch
Total before measuring and monitor
volume as it ows through the meter,
just like the gas pump at the service
station as you ll up your tank.
To zero the Batch Total, make sure
the meter is on. Hold down the
DISPLAY button for 3 seconds until
zeros appear. Release the button,
start the ow, and watch the volume
on the readout.
When display becomes dim, faded
or the low battery message appears
(see below), the batteries need to be
replaced. Reference the Computer
Maintenance Section for details.
INSTALLATION
LOWBAT

Foreign material in liquid can clog the
meter’s rotor. If the problem a󰀨ects
meter accuracy or material coats
the rotor, install screens to lter the
incoming ow.
– For Low Flow meters use a 25
micron or .005 inch screen, 120
mesh.
– For one inch or two inch meters
use a 500 micron or .018 inch
screen, 35 mesh.
For maximum accuracy, the velocity
prole of the ow entering the meter
must be uniform throughout the cross
section of the pipe.
Make sure there are no leaks in the
connections. To seal leaks, remove
and inspect the meter and replace
the thread tape or sealant. Refer to
the Troubleshooting Section.
METER MAINTENANCE
During daily use, these meters are
virtually maintenance-free.
When not in use, rinse and clean
and keep free of liquids to protect
internal components. If liquids have
dried and caked on the rotor, refer to
the Cleaning instructions.
To Remove
During meter removal, liquid
may spill. Follow the liquid
manufacturer's safety precau-
tions for clean up of minor spills.
WARNING
1. Ensure all liquid is drained from
the meter. This could include
draining the hose, meter, nozzle
or pipe.
2. Wear protective clothing as nec-
essary, loosen both ends of the
meter. Use a wrench only on the
meter’s at metal sur faces.
Using a wrench on plastic me-
ters could damage the meter.
CAUTION
3. If the meter is not immediately
installed again, cap the hose end
or pipe to prevent spills.
To Clean
During use, the meter should be kept
full of liquid to ensure that drying does
not occur inside the meter. If drying or
caking should occur, the rotor will stick
or drag, a󰀨ecting accuracy. In this
circumstance, cleaning is required.
To determine if the rotor is stuck or
dragging, gently blow air through the
meter and listen for the quiet whir of
the rotor.
Never blow compressed air
through the meter. It could dam-
age the rotor.
CAUTION
To clean a stuck or dragging rotor,
follow the procedures below.
1. Remove the meter from the hose
or pipe following the directions
above.
2. Apply a penetrating lubricant such
as WD-40®or a recommended
cleaning solvent on the turbine’s
rotor, shaft and bearings. Allow it
to soak for 10 to 15 minutes.
Do not submerge the meter.
CAUTION
3. Carefully remove residue from the
rotor using a soft brush or small
probe such as a screwdriver. Be
careful not to damage the rotor
and support.
4. When the rotor turns freely, install
it again following the Installa-
tion instructions provided in this
manual.
To Store
After thoroughly cleaning the meter,
store it in a dry location.
Follow the liquid manufacturer’s
instructions for the disposal of
contaminated cleaning solvents.

PRODUCT DESCRIPTION
INSTALLATION
INSTALLATION
This computer electronics is
designed specically for use on
GPI®Turbine Housings. It is also
designed to work with several
accessory output modules.
The CMOS, microprocessor-based
electronics have extremely low
power requirements and data
retention capabilities in both RAM
and ROM. Information is clearly
displayed on a large 6-digit LCD
readout with three-point oating
decimal for totals from
.001 to 999,999 (x1), 9,999,990
(x10), or 99,999,900 (x100). All
operations are easily accessed with
the two buttons on the front panel.
In a GPI turbine meter, liquid ows
through the turbine housing causing
an internal rotor to spin. As the
rotor spins, an electrical signal
is generated in the pickup coil.
This pulse data from the turbine is
translated into calibrated ow units
shown on the computer's display
readout.
Before installation, ensure your
computer model meets your specic
needs. Refer to the Specications
Section to conrm required
features. The model number of
your computer is displayed on
the outside wall of the computer
housing and also inside the
computer housing on the oor of the
battery holder.
If you ordered your computer
electronics with a turbine body,
the electronics are installed at the
factory.
If you ordered your computer
separately as a replacement, simply
mount the computer on your turbine
body with the four screws at the
corners of the faceplate. Make
sure the seal is fully seated before
tightening the screws.
If you ordered the computer
with a turbine body and an
accessory module, please review
and thoroughly understand all
installation instructions before
proceeding.
All GPI turbine meters are designed
to measure ow in only one
direction. The direction is indicated
by the arrow on the turbine outlet
port. If the computer display is
upside down in your installation,
remove the four screws, turn the
display 180 degrees and reinstall
the screws. (See Figure 6)

or modied at any time using a eld
calibration method described in this
section. Totals or owrate derived
from the eld calibration are being
invoked when the (FAC) icon is no
longer visible below the
6-digit display.
Factory calibration settings are
programmed into each computer
during manufacturing, using Stoddard
test solvent at 70° F (21° C) for
meters up to 1 inch. Meters 1-1/2 inch
and larger are factory calibrated using
water at 70° F (21° C).
Settings are correct for light liquids
such as water, gasoline or diesel.
Readings using the factory calibration
(FAC) may not be accurate in some
situations, for example, "heavy"
liquids such as motor oil, under
extreme temperature conditions, non-
standard plumbing congurations or
with uids other than
mentioned above.
For improved accuracy under such
conditions, the computer allows for
eld calibration, that is, user entry
of custom calibration parameters. A
"single point" eld calibration curve
may yield acceptable accuracy when
used in a non-standard application,
however, the computer is capable
of programming a “ve point” eld
calibration curve.
NOTE: If the calibration method is
changed when in calibration mode,
i.e., not using the default factory
calibration (FAC), the programming
will allow the user to adjust the user
programmable calibration table for
the calibration method selected. This
is done by shunting the user to the
eld calibration method entry menu
specic to that calibration method
upon exit from the calibration mode.
For the most accurate results,
dispense at a owrate which best
simulates your actual operating
conditions. Avoid "dribbling" more uid
or repeatedly starting and stopping
the ow. This can result in less
accurate calibrations. Make sure you
meet the meter's minimum owrate
requirements.
• Low Flow meter: 0.3 GPM
(1.1 LPM)
• 1 inch meter: 3.0 GPM
(11 LPM)
• 2 inch meter: 30 GPM
(113 LPM)
The use of a uniformly dependable,
accurate calibration container is
recommended for the most accurate
results. A ve gallon calibration
container is available in the parts
section of this manual. For best
results, the meter should be installed
and purged of air before eld
calibration.
Due to high owrates on meters
2 inch and larger, it is strongly
recommended that eld calibration
be completed with a combination of
volume and weight determined with
ne resolution scales.

Field Calibration Method
Display Dispense Method
At the beginning of the calibration
method entry menu, the software will
allow the user to start the calibration
process or to exit back to normal
operation. (See Figures 11-1 & 11-2)
The bottom row of characters will be
in focus to indicate that the user can
select between either “Start” or “Exit” by
advancing focus.
Dispense/Display is a eld calibration
method by which the user will dispense
a known volume of uid and the
software will keep track of the pulse
count during the dispense operation.
The user will then enter the known
volume into the display and the
software will calculate a K-factor for the
volume dispensed.
If “Start” is in focus when advancing to the next
menu, the software will automatically advance
to the calibration menu for the calibration
method the user previously selected.

If “Exit” is in focus when advancing to the
next menu, the display will return to normal
operation.
Figure 11-2
Figure 24-2
The rst screen in this calibration method will
show “run 1” indicating that computer is waiting
for ow to start. (See Figure 12-1)
NOTE: Pressing any single button while on this
screen will not have any e󰀨ect. Pressing both
buttons and holding will allow the user to exit
calibration mode.

FIELD CALIBRATION MODE (CONTINUED)
OPERATION (CONTINUED)
When the user is nished with the
run, press and hold the Display button
until the left most digit begins to ash
indicating it is in focus, then release the
Display button.
Pressing the Calibrate button will
increment the digit in focus. Pressing
the Display button will advance focus to
the next digit.
Holding Display and pressing Calibrate
will lock in the entered volume. (See
Figure 14-2)
The software will then calculate the
K-factor for the volume entered based
on the pulse count for the run and
the volume entered. The average
frequency and the K-factor will be
entered into the custom user K-factor
table for run 1.
Begin dispensing into a container of known
accurate volume. As soon as pulses are
detected by the software, the screen will switch
to display the volume being dispensed on the
top row and the volume unit on the bottom row.
(See Figure 12-2)
Figure 12-2
NOTE: After 3 seconds, “FldCAL” will then
be displayed on the top row and “Exit” on the
bottom row (see Figure 14-2) until the user
releases both buttons. The software will store
the sorted table of frequencies and K-factors.
Exit Dispense Display Method
This menu is used to indicate to
the user they are exiting the eld
calibration mode menu. The user can
exit any of the calibration methods
at any time. To exit, press and hold
the Display and Calibrate buttons
simultaneously for 3 seconds; the
software will display a three second
count down (see Figure 14-1), then
reset to show the exit display. (See
