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 com‑
patible with all wetted materials.

2. When measuring ammable liq‑
uids, observe precautions against

re or explosion.

3. When handling hazardous liq‑
uids, always follow the liquid
manufacturer’s safety precau‑
tions.

4. When working in hazardous
environments, always exercise
appropriate safety precautions.

5. For best results, always verify
accuracy before use.

Product Description

These computer electronics are

designed specically for use on GPI

Commercial Grade Turbine Hous‑
ings.

The CMOS, microprocessor‑based
electronics have extremely low pow‑
er 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 equip‑
ment for visible damage. The com‑
puter is a precision measuring
instrument and should be handled as
such. If any items appear damaged
or missing, contact your distributor.

Make sure 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
lower side of the computer and also
underneath a battery.

INSTALLATION

If you ordered your computer elec‑
tronics with a turbine housing, it is
installed at the factory.

If you ordered your computer sepa‑
rately 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 un‑
derstand 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 opposite direction is
desired, simply rotate the computer
electronics 180 degrees prior to
installation.

Avoid electronically “noisy”
environments. Install at least 6
inches (15.2 cm) away from motors,
relays, or transformers.

All GPI A1 Series meters are Factory
Mutual Approved and carry a Class
1, Division 1 Approval for hazardous
environments. In addition, GPI meters
have NEMA Type 4 enclosures.
They are tested and calibrated at
the factory using state‑of‑the‑art
calibration procedures and testing
equipment.

To ensure accurate measurement,
remove all air from the system before
use.

1. Ensure some back pressure on
the turbine.

2. Open the discharge valve
or nozzle and allow fluid to

completely ll the system. Make

sure the stream is full and steady.

3. Close the discharge valve or
nozzle.

4. Start normal operations.

It is strongly recommended that

accuracy be veried 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 figure final volume. For best

results, accuracy should be veried

periodically as part of a routine
maintenance schedule.

OPERATION

Computer Display

All operations are reected in the

LCD readout. The large center digits
indicate amounts, where smaller
words or “icons” located above and

below indicate specic 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 field
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 con‑
tinuous measurement and cannot
be manually reset. The Batch Total

can be reset to measure ow during

a single use. The Cumulative Total
is labeled 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 zeros must be added to the
6 digits shown.
