DESCRIPTION
The GFC-111EA-B is a two input flow computer /
totalizer that can be used to measure diesel engines
fuel consumption and many other applications that
require measuring the sum or the difference of two
flow rates and totals. Input A is universal, input B
accepts a variety of flow sensors. Input A provides
regulated and filtered 10 VDC power for the sensor.
Input B does not.
- The GFC-111EA-B has an isolated no-polarity
100V/100mA DC/AC output that can be programmed
to work as a rate alarm or pulse output.
- The alarm can be programmed to be high or low
and to compare against rate A, rate B, A+B or A-B.
- The pulse output can be programmed for low or
high frequency and to represent total A, total B, A+B
or A-B.
- The GFC-111EA-B also has one isolated analog 4-
20 mA output that can be programmed to represent
rate A, rate B, A+B or A-B.
- A programmable filter (damping) for each input
helps to generate a stable flow rate reading.
- A programmable flow rate cut-off for each input can
halt the reading when the flow becomes unstable.
- The GFC-111EA-B has a version in one inch wider
enclosure – GFC111E-A-B.
The GFC-111EA-B is the perfect solution for flow
measurement and control applications that require
high accuracy and reliability, electrical isolation,
output signals, small
performance and low maintenance.
