Before Getting Started
Take the time to fully acquaint yourself with all information about the
components of your GPI Electronic
Digital Meter. If you need assistance,
contact the distributor from whom
you purchased your computer.
This symbol is used throughout the manual to call your
attention to safety messages.
WARNING
CAUTION
Warnings alert
you to the potential for personal
injury.
Caut i o n s call
your attention to
practices or procedure s w h i c h
may damage your
equipment.
Notes give information that can
improve efciency of operations.
It is your responsibility to make sure
that all operators have access to adequate instructions about safe operating and maintenance procedures.
Read Me!
For your safety, review the major
warnings and cautions below before
operating your equipment.
WARNING
The apparatus enclosure may
contain aluminum and is considered to constitute a potential risk
of ignition by impact or friction.
Care must be taken into account
during installation and use to
prevent impact or friction.
WARNING
Part of the enclosure is constructed from plastic. To prevent
the risk of electrostatic sparking
the plastic surface should only
be cleaned with a damp cloth.
1. This equipment is approved to
handle only uids that are compatible with all wetted materials.
2. Wh en me asur ing fl amma ble
liquids, observe precautions
against re or explosion.
3. When handling hazardous liquids, always follow the liquid
manufacturer’s safety precautions.
4. Wh en working in haz ardous
environments, always exercise
appropriate safety precautions.
5. For best results, always verify
accuracy before use.
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.

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.
