GENERAL INFORMATION
This manual will assist you in operating and maintain-
ing the GPI electronics supplied with your GPI meter or
as an accessory unit on both local and remote models.
The GPI Electronics can be used in indoor or outdoor
applications where occasional exposure to moisture is
common.
Display information in this manual supersedes display information provided with your meter.

Remote Model
The Scaled Pulse Module can be used on all GPI
models, including the Precision G series, IM or the
Industrial Grade G2 series, the Commercial Grade A1
series and the Positive Displacement GM series oval
gear meters.
Product differences in this manual are identified by either
Local or Remote as necessary.
The GPI Scaled Pulse Module is a switch-programmable
multi-stage counter/divider with multiple inputs. Its
function is to provide a pulse output for each number of
input pulses. Input pulses are assumed to come from a
frequency-output flowmeter mechanism.
GPI flowmeters have a "K-factor" which is the pulse
output per unit volume measured stated as "Pulses Per
Gallon" (PPG). Other flowmeters also have a "K-factor"
as determined by their manufacturer. Verify the "K-factor"
unit of measurement before programming this equip-
ment. In a flowrate-measuring system, it's desirable
to have an output signal that has been converted to
a standard unit of measure, such as gallons. Such an
output can then be used to drive "off-the-shelf" display
units and/or relays.
