Product Description
These computer electronics are
designed specically for use on GPI
Commercial Grade Turbine Housings.
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 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 you r turbine, simpl y
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.
