For best results, take the time to fully
acquaint yourself with all information
about all components of your GPI
Electronic Digital Metering System
prior to installation and use. If you
need assistance, contact the distribu‑
tor from whom you purchased your
turbine.

It is your responsibility to make sure
that all operators have access to
adequate instructions about safe op‑
erating and maintenance procedures.

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 materials of
construction.

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

re or explosion.

3. When handling hazardous liquids,
always follow the liquid manufac‑
turer’s safety precautions.

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

5. Always dispose of used cleaning
solvents in a safe manner accord‑
ing to the solvent manufacturer’s
instructions.

6. During turbine removal, liquid
may spill. Follow the liquid manu‑
facturer’s safety precautions for
clean up of minor spills.

7. Do not blow compressed air
through the turbine.

8. Do not allow liquids to dry inside
the turbine.

9. Handle the rotor carefully. Even
small scratches or nicks can affect
accuracy.

10. When tightening the turbine, do
not use a wrench or pliers to
tighten the turbine. Hand tighten
only.

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

Product Description

GPI Industrial Meter Turbines are

identied by the internal diameter of

the inlet and outlet.

Model 05 ‑ 1/2 inch
Model 10 ‑ 1 inch

Each turbine is designed to work with
on‑board computer electronics and/or
with one of several accessory mod‑
ules that can interface to a wide variety
of reporting and collecting devices.

Liquid ows through the turbine hous‑
ing causing an internal rotor to spin.
As the rotor spins, an electrical signal
is generated in the pickup coil. The
electrical signal provides the output
necessary to operate the on‑board
computer electronics for local indica‑
tion directly on the turbine or one of
several accessory modules that trans‑
mit the signal to external equipment.

Upon receipt, examine your meter
for visible damage. The turbine is a
precision measuring instrument and
should be handled as such. Remove
the protective plugs and caps for a
thorough inspection. If any items are
damaged or missing, contact your
distributor.

Make sure the turbine model meets

your specic needs. Refer to the
Specications Section and conrm

the following:

3921915-02 Rev. E

1. The owrate is within the limits of

your model.

2. The liquid is compatible with the
turbine’s wetted components.

3. The system’s pressure does not
exceed the turbine’s maximum
pressure rating.

Each GPI Turbine has a unique iden‑

tication number that includes the

Serial Number, K‑Factor and Manu‑

facturing Date. This identication

number is etched into the surface of

the turbine. Record this identication

number in the back of the Owner’s
Manual in the space provided.

INSTALLATION

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, and you
are using on‑board computer electron‑
ics, rotate the computer electronics
180 degrees prior to installation.

Diagram 1

Flow altering devices such as elbows,
valves, and reducers can affect ac‑
curacy. The following recommended
guidelines are given to enhance ac‑
curacy and maximize performance.
Distances given here are minimum
requirements; double them for desired
straight pipe lengths.

Upstream from the turbine, allow
a minimum straight pipe length at

least 10 times the internal diameter
of the turbine. For example, with
the 1 inch turbine, there should be
10 inches (25.4 cm) of straight pipe
immediately upstream. The desired
upstream straight pipe length is 20
inches (50.8 cm).

Downstream from the turbine, allow
a minimum straight pipe length at
least 5 times the internal diameter
of your turbine. For example, with
the 1 inch turbine, there should be 5
inches (12.7 cm) of straight pipe im‑
mediately downstream. The desired
downstream distance is 10 inches
(25.4 cm).

A typical back pressure of 5 to 50 PSI
(0.34 to 3.4 bar) will prevent cavitation.
Create back pressure by installing a
control valve on the downstream side
of the meter at the proper distance
detailed above.

Foreign material in the liquid being
measured can clog the turbine’s rotor
and adversely affect accuracy. If this
problem is anticipated or experienced,

install screens to lter impurities from

incoming liquids.

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

1. Ensure some back pressure ex‑
ists on the turbine in the line.

2. Open the discharge valve or
