universal 5 kHz input, no amplifiers or linearizers needed, isolated 4-20 mA output, programmable decimal
places for the rate and all totals, calibration curve, multiple outputs, batch controller. KFACTORs from
0.001 to 9,999,999.
- GFC101L flow computer /totalizer is a software version of GFC101 that can handle better very low input
frequencies (down to 1 pulse every 3-4 seconds) with a very stable reading for the flow rate at these low
frequencies
- GFC101V - no digital output, analog output is isolated 0 - 5V, 12 bit, 0.05%
- Micro power flow computer / totalizer GFC102. Input accepts coils, waves and logical signals, up to 5kHz.
Calibration tables can be entered for higher accuracy. No need of amplifiers or linearizers. Programmable
decimal places for the rate.
- Micro power flow computer / totalizer GFC104 has separate volume units for rate and total and a
simplified 2 level menu. A "C" size battery option available for sensors with higher consumption.
- Low power flow computer / totalizer GFC110. 12 bit Isolated 4-20 mA output for rate (RPM),
programmable. Fast, less than 10 ms response time version available. Isolated 100V/100mA, no polarity
pulse output up to 30 000 pulses per minute (500 Hz) ...
- GFC110P has no resistor in series with the power to the sensor and provides stable and regulated voltage.
- Low power flow computer / totalizer with universal input GFC111. Accepts npn, pnp, open
drain/collector, logical signals, wave, dry contact, reed, proximity switches, NAMUR, Data Industrial,
coils ... No external amplifiers or linearizers needed. Fast analog output version ...
- GFC111L flow computer / totalizer is a software version of the standard GFC111 that can work better
with frequencies as low as 0.2-0.3 Hz and provide stable reading for the flow rate at these low frequencies
- Low power flow computer / totalizer with universal input GFC113. Fast, 10 ms response time 0-5V or 4-
20mA output. Rate is auto-ranged, total has programmable decimal places.
- GFC114 is a version of GFC111 low power flow computer/totalizer with very simple and easy to use
menus, no batch, no limit, no data logging, total B and C are non-resettable
- GFC200 low power flow computer / totalizer compensates for the temperature of the liquid when used for
gasoline or diesel. The temperature compensation can be disabled and then the flow computer can be used
for any other liquid
- GFC201 low power flow computer / totalizer is similar to GFC200 but has a 0-5V output linear to the
temperature measured by the transmitter connected and another 0-5V programmable output linear to the
flow rate. GFC201 is specially designed to have full functionality working on a car battery.
- GFC204 low power flow computer totalizer with temperature compensation, universal input, 0-5V isolated
analog output, no digital output (no batch, pulse, alarm or limit)
- GFC111-MB low power flow computer / totalizer has all the features of GFC111 + RS485 MODBUS
RTU communication capabilities. The RS485 driver is 1/8 allowing up to 247 devices on a 2 wire RS485
network. The flow rate and the total A can be read many times a second remotely by the master on a
single computer, SCADA, PLC, a network or transmitted over a wireless link.
- GFC420 low power flow computer / totalizer has an analog 4-20 mA input for flow rate and works with
differential pressure sensors taking a square root of the signal or just regular flow meters with and analog
output
