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 flow 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° and reinstall the screws.
Avoid electronically "noisy" environ-
ments. Install the computer at least
15.2 cm (6 inches) away from motors,
relays, or transformers.
Verify Accuracy
Before use, check the accuracy and
verify calibration. Make sure there
is no air in the system. Measure an
exact known volume into an accurate
container. 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 verified
periodically as part of a routine
maintenance schedule.
OPERATION
Computer Display
All operations are reflected in the
LCD readout. The large center digits
indicate amounts, where smaller
words or "icons" located above and
2
below indicate specific information
regarding totals, flow, 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
continuous measurement and cannot
be manually reset. The Batch Total
can be reset to measure flow 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 briefly to
switch between the TOTAL 1, TOTAL
2 BATCH and FLOWRATE. Press
DISPLAY briefly to display the TOTAL
2 BATCH. Hold the DISPLAY button
for 3 seconds to reset the Batch Total
to zero.
When fluid is flowing through the
meter, a small propeller icon is
highlighted.
