INTRODUCTION
Your GPI Electronic Digital Meter is designed for measuring liquids. The meter
translates pulse data from the turbine into calibrated flow units shown on the
meter’s readout. Field replaceable batteries provide power.
All meters are tested and factory calibrated before shipping.
This manual refers to three families of meters: (Low Flow), (One Inch), and (Two
Inch). To further identify your particular model, refer to the Specifications Section
in this manual.

6
BEFORE INSTALLATION
Upon receipt, examine your meter for visible damage. Remove protective plugs
and caps for a thorough inspection. If any items are damaged or missing, contact
your distributor.
Make sure the meter model meets your specific needs. Refer to the Specifications
Section and confirm the following:
1. The flowrate is within the limits of your model.
2. The liquid is compatible with your meter’s material.
3. Your system’s pressure does not exceed the meter’s maximum pressure
rating.
Information specific to your particular turbine, including serial number and
manufacturing date is printed on the bottom of the turbine.
For your future reference, it might be useful to record this information in this manual
in case it becomes unreadable on the turbine.
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 viscosity
fluids dispensed through a hose and nozzle.
If you complete this section and encounter difficulties, please refer to other
sections, as necessary.
NOTE: To accommodate different 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
assembly 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 compatible with the liquid
being metered. (Figure 1)
Make sure the thread tape or
sealing compound does not
interfere with flow.
Figure 1

BEFORE INSTALLATION (continued)
Connections (continued)
2. Make sure the arrow on the outlet is pointing in the direction of the flow.
(Figure 2)
Figure 2
3. Tighten the meter onto the fittings. Use a wrench only on metal meters.
Hand tighten plastic meters.
Using a wrench on plastic meters could damage the
meter.
Verify Meter Accuracy
Before using, you should check the meter’s accuracy and verify calibration.
1. Make sure there is no air in the system by starting the flow until it runs
steadily. Then, stop the flow 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, field calibrate the meter. Refer to the
Calibration Section.
4. To ensure accurate measurement, remove all air from the system before
use. To purge the system of air:
a. Open the discharge valve or nozzle and allow fluid to completely fill
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 necessary, zero the Batch Total.
Using the Meter
The meter display is on continually and always ready for use.
To determine the exact volume measured with each use, use the Batch Total
function. You can zero the Batch Total before measuring and monitor volume as it
flows through the meter, just like the gas pump at the service station as you fill up
your tank.

8
BEFORE INSTALLATION (continued)
Using the Meter (continued)
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 flow, and watch the
volume on the readout.
When display becomes dim, faded or the low battery message (LOWBAT)
appears, the batteries need to be replaced. Reference the Computer Maintenance
Section for details.
METER INSTALLATION
Review the Before Installation and Quick Start Sections. Also consider the
following recommendations, especially 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 field
calibrated in the same orientation in which it is mounted.
Avoid installing the meter in electrically “noisy” environments. If installed within 6
inches (15.2 cm) of large motors, relays, vehicle ignition systems, or transformers,
the meter’s accuracy can be adversely affected.
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 affect meter accuracy. This is especially true when
measuring liquids with low vapor pressures such as fuels, oils and solvents.
If cavitation effects meter accuracy, a flow 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.
Foreign material in liquid can clog the meter’s rotor. If the problem affects meter
accuracy or material coats the rotor, install screens to filter the incoming flow.
•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 profile of the flow 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.

9
METER MAINTENANCE
During daily use, these meters are virtually maintenance-free.
When not in use, rinse, 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 Re ove
During meter removal, liquid may spill. Follow the liquid
manufacturer's safety precautions for clean up of minor
spills.
1. Ensure all liquid is drained from the meter. This could include draining the
hose, meter, nozzle or pipe.
2. Wear protective clothing as necessary; loosen both ends of the meter. Use
a wrench only on the meter’s flat metal surfaces.
Using a wrench on plastic meters could damage the
meter.
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,
affecting 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
damage the rotor.
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.
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 installation
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.

Q9 INSTALLATION
PRODUCT DESCRIPTION
This computer electronics is designed specifically 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 floating 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 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 from the turbine is translated into calibrated flow units shown on
the computer's display readout.
INSTALLATION
Before installation, ensure your computer model meets your specific needs. Refer
to the Specifications Section to confirm 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 floor 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 flow 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)
NOTE: When rotating the computer
display, it is not necessary to
disconnect the pickup coil connector;
however, care should be taken to avoid
inadvertent strain on the connector
wires.

Q9 OPERATION
COMPUTER DISPLAY
All operations are revealed on the LCD using the large 6-characters in the top row
and smaller characters and symbols in the second row. These characters and
symbols indicate information regarding totals, flow, calibration, units of measure
and operational messages.
Push button operation varies dependent upon the various modes of operation, i.e.
Normal Operation mode and Field Calibration mode. Their operation will be
described in their respective sections.
ACTIVATE THE COMPUTER
When batteries are installed, the computer is on continuously and always ready to
perform. The computer is powered by field replaceable commercially available
batteries. Reference the computer maintenance section for battery replacement
details.
When batteries are initially installed or
replaced, the initialization routine will start
the LCD display blank, and then display
“HELLO” on the top row and “Q9Disp” on
the information row for one second.
(See Figure 7)
Figure 7
The LCD will then display “HELLO” on the
top row and “FW Vxx” on the information
row for one second. The Vxx will be the
version of the software installed on the
display. Example: “FW V03” indicates
firmware version 3 installed on the display.
(See Figure 8)
General
The computer maintains two totals; batch total and accumulative total. The batch
total can be reset to measure flow during a single use. The accumulative total
provides continuous measurement; and can only be reset by removing the
batteries, holding down the Display button, and replacing the batteries.
The button usage map on the next page is useful for understanding where the
various menus are located within the software programming and the route to get

Q9 OPERATION (continued)
FIELD CALIBRATION MODE
Field Calibration Method
General
The field calibration method may be set by the user, and can be changed or
modified at any time using a field calibration method described in this section.
Totals or flowrate derived from the field 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 configurations or with fluids other than mentioned above.
For improved accuracy under such conditions, the computer allows for field
calibration, that is, user entry of custom calibration parameters. A "single point"
field calibration curve may yield acceptable accuracy when used in a non-standard
application, however, the computer is capable of programming a “five point” field
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 “field calibration method entry menu”
specific to that calibration method upon exit from the calibration mode.
Verify Accuracy before Beginning Field Calibration
For the most accurate results, dispense at a flowrate which best simulates your
actual operating conditions. Avoid "dribbling" more fluid or repeatedly starting and
stopping the flow. This can result in less accurate calibrations. Make sure you meet
the meter's minimum flowrate 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 five-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 field calibration. Due to high flowrates on meters 2 inch and
larger, it is strongly recommended that field calibration be completed with a
combination of volume and weight determined with fine resolution scales.
