1. DESCRIPTION
The GFC-101E is a micro power battery powered
flow computer totalizer
combination of excellent features, extremely long
battery life, universal input, high input frequency and
a variety of outputs. It accepts open drain/collector
npn/pnp, reed switch, dry contact, coils, almost any
wave and logical signals. GFC-101E has an open
drain 100V/100mA output that can be programmed
to work as a rate alarm:- high or low, with +/- 1 %
hysteresis, batch, limit or pulse output.
Regardless of the type of output chosen, GFC-
101E stores up to 64 totals for each 24 hours that
can be easily viewed on the liquid crystal display.
For improved accuracy, the GFC-101E provides
capabilities of using calibration tables for up to 10
points. In seconds the operator can switch between a
single K-FACTOR and the curve of up to 10 points.
The GFC-101E software implements a version of
our proprietary predictive/adaptive, self-adjusting
digital filtering which provides extremely stable
reading at any input frequency, plus very fast
response to any change in the flow.
The GFC-101E has an option for panel mount in
DIN 72x72 mm box.
The GFC-101E is the perfect solution for flow
measurement and control applications that require
high accuracy and reliability, small size, industrial
grade performance and low maintenance, at an
affordable price.
