Gas Flow TotaliserGFC-147 - The perfect solution to your Gas Flow measurement needs
Sometimes referred to as EFM ( Electronic Flow Meter) or Mass Flow Computer ( MFM), our Gas Flow Computer GFC-147 has an internal database of physical properties of most commonly used industrial gases.
It measures Gas Pressure and Temperature and uses extremely complex algorithms for calculations of Gas Density & Compressibility all in real time.
It also uses algorithms conforming to International standards like ISO 5167 to compute Flow from Orifice Plates, Ventures, Flow Nozzles, Pitot Tubes etc. and corrects for factors like Reynolds number when the flow is computed.
So, it can be connected to any of these standard Flow measuring systems such as
Vortex Flowmeter
Orifice Plate, DPT
Pitot Tube, Venturi, ''Verabar'' etc.
The Flow Computer can easily be interfaced to SCADA or DCS systems as various options like Analog Retransmission and RS485-MODBUS outputs are available.
Extensive Database of gases
Compressed Air, Ammonia, Iso-Butane, N-Butane, CO2, CO, Chlorine, Ethane, Ethylene, Helium, Hydrogen, Nitrogen, Oxygen, Propylene, Argon
LPG, Propane, Methane, Producer Gas

Preset Temperature or Pressure values
The values of Temperature and Pressure can be programmed in case on-line signals are not available or a transmitter failure.
Two levels of passwords
One for the user and another for instrument configuration to avoid un-authorised tampering.
Non-volatile memory to retain Totalised Flow, no batteries to change or fail.
Retransmission 4-20ma analogue output can be dedicated to representing any variable.
RS485/RS232 MODBUS interface Graphical Trend for Flow.
