Product Description
These computer electronics are
designed specically for use on GPI
Industrial Grade Turbine Housings.
They are 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
two-point oating decimal for totals
from .01 to 999,999. All operations
are easily accessed with the two
buttons on the front panel.
Liquid flows 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 is translated from
the turbine into calibrated ow units
shown on the computer’s readout.
Upon receipt, examine your equipment for visible damage. The compu ter is a prec isio n meas urin g
instrument and should be handled as
such. If any items appear damaged
or missing, contact your distributor.
Make sure your computer model
meets your specic needs. Refer to
the Specications Section to conrm
required features. The model number
of your computer is displayed on the
lower front side of the computer and
also underneath a battery.
INSTALLATION
If you ordered your computer electronics with a turbine housing, it is
installed at the factory.
If you ordered your computer separately from your turbine, simply mount
the computer on the turbine with the
four screws at the corners of the
faceplate. Make sure the seal is fully
seated before tightening the screws.
3
If you ordered the computer with
turbine and an accessory module,
please review and thoroughly understand all installation instructions
before proceeding.
All GPI turbines are designed to
measure ow in only one direction.
The direction is indicated by the arrow cast-molded in the turbine outlet.
If the computer display is upside
down, remove the four screws, turn
the display 180 degrees and reinstall
the screws. See Diagram 1.
Diagram 1
Avoid electronically “noisy” environments. Install at least 6 inches
(15.2 cm) away from motors, relays,
or transformers.
Our computer electronics are Factory
Mutual Approved, C-UL Classied
and carry a Class 1, Division 1 Approval for hazardous environments.
In addition, GPI meters have NEMA
Type 4 enclosures.
To ensure accurate measurement,
remove all air from the system before use.
It is strongly recommended that accuracy be veried prior to use. To do
this, remove all air from the system,
measure an exact known volume
into an accurate container, and verify
the volume against the readout or
recording equipment. If necessary,
use a correction factor to gure nal
volume. For best results, accuracy
should be veried periodically as part
of a routine maintenance schedule.

OPERATION
Computer Display
All operations are reected in the
LCD readout. The large center digits
indicate amounts, where smaller
words or “icons” located above and
below indicate specic information
regarding totals, ow, calibration and
units of measure.
Activate the Meter
Computer is on continuously and always ready to perform. The computer
is powered by eld replaceable batteries. When display becomes dim,
faded or the low battery message
appears (see below), the batteries
need to be replaced. Reference the
Maintenance Section for details.
Batch and Cumulative
Totals
The computer maintains two totals.
The Cumulative Total provides continuous measurement and cannot
be manually reset. The Batch Total
can be reset to measure ow during
a single use. The Cumulative Total is
labeled with TOTAL 1, Batch Total is
labeled TOTAL 2 BATCH.
When the Cumulative Total reaches
a display reading of 999,999 the
computer will highlight an X10 icon.
This indicates to the operator that a
zero must be added to the 6 digits
shown. When the next rollover occurs,
the computer will highlight an X100
icon. This indicates to the operator
that two zeroes must be added to
the 6 digits shown.
Press the DISPLAY button briey to
switch between the TOTAL 1, TOTAL
2 BATCH and FLOWRATE. Press
DISPLAY briey to display the TOTAL
2 BATCH. Hold the DISPLAY button
for 3 seconds to reset the Batch Total
to zero.
When uid is owing through the
meter, a small propeller icon is highlighted.
NOTE: Totalization counts total units
without differentiating between
gallons, litres or eld calibrated
units.
Flowrate Feature
(some models)
To use this feature, press and release DISPLAY until FLOWRATE
icon appears. The factory set time
base will be highlighted to the right of
FLOWRATE (M = minutes, H = hours,
D = days). When FLOWRATE is invoked, the display will be indicating
rate of ow.
Switching between different units will
not corrupt the Total’s contents. For
example, in GL mode, the computer
totalizes 10.00 gallons, if the user
switches to LT mode, the display will
read 37.85 litres (the same volume,
different unit).
The “eld” calibration may be set by
the user, and can be changed or modied at any time using the calibration
procedure described in the Calibration Section. Totals or owrate derived
from the eld calibration are invoked
when the FAC icon is no longer visible
on the top line of the display.
CALIBRATION
Factory and Field
Calibration
All calibration information is visible to
the user as icons on the top line of
the display, above the numeric digits.
All units are congured with a “factory” calibration. Both gallons and
litres are available (“GL” or “LT” will
be displayed). While holding the
CALIBRATE button, briey press
DISPLAY to toggle between gallons
and litres. This factory calibration
(indicated with FAC) is permanently
programmed into the computer and
is not user adjustable.
NOTE: Your computer may have oth-
er units of measure programmed
into it. If so, holding the CALIBRATE button and momentarily
pressing the DISPLAY button
will toggle through all factory set
units. Other possible units are:
IGL (imperial gallon), QT (quart),
CF (cubic feet), CM (cubic meter),
BL (42 gal. barrel), CC (cubic
centimeter) or OZ (ounce).
Verify Accuracy Before
Beginning Field Calibration
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:
1/2 in. meter 1 GPM (3.8 LPM)
3/4 in. meter 2 GPM (7.6 LPM)
1 in. meter 5 GPM (18.9 LPM)
1-1/2 in. meter 10 GPM (37.9 LPM)
2 in. meter 20 GPM (75.7 LPM)
The use of a uniformly dependable,
accurate calibration container is
recommended for the most accurate
results. For best results, the meter
should be installed and purged of air
before eld calibration.
Due to high owrate on the 2 inch
meter, it is strongly recommended
that Field Calibration be completed
with a combination of volume and
weight determined with ne resolution scales.

Field Calibration Necessity
Field Calibration and Factory Calibration are dened in the Operation
Section. Factory calibration settings
are programmed into each computer
during manufacturing, using stoddard
test solvent at 70° F (21° C) for low ow
and 1-inch meters and water at 70° F
(21° C) for 2-inch meters. 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
congurations 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” calibration may yield
acceptable accuracy when used in
a non-standard application.
Field Calibration
Procedures
(Correction Factor Method)
1. To calibrate, press and hold the
CALIBRATE and DISPLAY buttons for about 3 seconds until
you see FLdCAL. Release both
buttons and you will see CF - 00.0.
You are now in the eld calibration
mode and values from -99.9% to
+99.9% can be entered.

be pushed to select the numeric
positions. Press the CALIBRATE
button to scroll from 0 to 9. Enter
the percentage of change you
want the display to correct. When
satised with the value, press
both CALIBRATE and DISPLAY
buttons simultaneously. CALEnd
will be displayed and unit will go
back to normal operation, less the
FAC (factory calibration) icon.
4. All enabled units-of-measure remain visible and selectable – the
entered correction will be applied
to all enabled units.
5. To return to factory calibration
(FAC), press and hold both CALIBRATE and DISPLAY buttons for
about 3 seconds until FAcCAL is
displayed. Then release buttons.
Unit should return to normal operation and FAC icon is visible.
USER CONFIGURATION
The “09” series GPI display has
been programmed with many new
features, most of which can be enabled by the end user by way of a
conguration process. By disabling
“unnecessary” features, day-to-day
owmeter operation can be greatly
simplied, making the unit easier to
use. There are several features that
GPI disables by default when shipping standard meters. (For example,
K-Factor Entry Field Calibration, described below.) For more advanced
users, it may be desirable to enable
ALL possible features. User congurable features include:
• Totalizers/Modes Enabled (Cumu-
lative Total, Batch 2 Total, Flowrate
Mode)
• Flowrate Timebase (Units per
Minutes, Hours and Days)
• Factory Calibration Curve Units
Enabled (Gallons, Imperial Gallons, Litres, Quarts, Ounces, Cubic
Feet, Cubic Centimeters, Cubic
Meters or Barrels (42 gal.)
• Dispense/Display or K-Factor En-

Changing Conguration
Settings
Access to the configuration process is restricted for security until a
“password” is entered. Contact your
distributor or GPI to get the password
and instructions to unlock and reset
conguration settings. This information is also available on the GPI Web
site. Congurations are entered and
stored as six-digit “codes” where
each digit represents a setting for
one of the conguration options. New
conguration settings are stored in
the computer’s long-term memory
and will not be lost either in OFF
mode or during battery change.
K-Factor Entry Field
Calibration
Presently all GPI computers are
programmed with three different
eld calibration methods, only one
of which is active, the “correction/
factor” calibration procedure described above. It is possible to activate “K-Factor entry” or “dispense/
display” eld calibration by changing
conguration settings. Contact your
distributor or GPI to get the correct
password, conguration code, and
instructions for this calibration method. This information is also available
on the GPI Web site.
MAINTENANCE
When batteries are disconnected or
fail, the Batch and Cumulative Totals
will maintain the value they had.
Factory and Field Calibration Curves
are retained in the meter’s computer
when power is lost.
It is strongly recommended that
battery check and terminal cleaning
be a part of a routine maintenance
schedule. Battery terminals should
be cleaned annually. Batteries can be
replaced without removing the meter
from the piping system.
Replace Batteries
1. Remove the corner screws from
the meter face and lift the computer electronics from the turbine.
2. Remove the batteries.
3. Check the battery terminals and
remove any corrosion.
4. Install the new batteries and
make sure the positive posts
are positioned correctly. When
the batteries are installed correctly, the computer powers on
automatically and the readout
displays information.
5. Make sure the seal is fully seated
before placing the computer electronics on the turbine. Tighten the
four screws.
6. Do not clean exterior of computer
assembly with Isopropyl Alcohol.
The computer electronics is powered
by lithium batteries. Removing the
batteries before storing the meter
will extend battery life. If the meter’s
readout should become dim, blank
or the low battery message appears
(see below), the batteries should be
replaced. Replacement batteries can
be ordered from your distributor or
the factory. See details in the Parts
Section.
