GFC300 Series Flow Computers / Totalizers For Steam

Flow Computer totalizer for steam with MODBUS RTU

GFC319 is a DIN 96x96 panel mount flow computer / totalizer for steam with extremelly high accuracy and accepts signals from almost any volume flow meter. GFC319 calculates density, enthalpy, heat rate, net heat, delta heat and total heat of steam with high accuracy by IAPWS-IF97 with the new additions from 2008.

It has one analog output that can be configured for active or passive, 0-20 mA, 4-20 mA, 0-5V, 0-10V, 1-5V or 2-10V on the field at any time. Its pulse output can also be configured on the field for open drain or 5 V square wave. GFC319 has a temperature input that accepts directly a Pt100 RTD. It has another input that can be configured for a second Pt100 RTD (second temperature for saturated steam delta heat) or for 4-20 mA pressure signal. Two normal open relay contacts for alarms can be set to be high or low independently. GFC319 flow computer / totalizer also has a fully compliant programmable RS485 MODBUS RTU port for baud rates up to 115 200.



Dual Flow Computer totalizer for liquids, gases and steam with MODBUS RTU

GFC300 is a dual channel DIN 144x72 panel mount flow computer / totalizer for liquids, gases and steam with extremelly high accuracy that can accept signals from almost any volume flow meter. It can be set as a single channel, two independent channels or both channels can be used to calculate, display and control outputs with the sum or the difference of the totals, the sum of the flow rates, and other calculations.

GFC300 has preset lists of liquids and gases for easier programming. It calculates the compressibility factors of the preset gases with high accuracy in a very large range of temperatures and pressures.

GFC300 also calculates density, enthalpy, heat rate, net heat, delta heat and total heat of steam with high accuracy by IAPWS-IF97 with the new additions from 2008.

With its variety of isolated outputs GFC300 can control metering pumps, DC motor pumps, connect to SCADA systems, PLCs, remote displays and many other devices. When used as a dual flow computer it can be very useful when mixing gases or liquids in exact proportion, controlling the total flow of two different pumps filling the same tank, measuring the fuel used by diesel engines and many others. GFC300 flow computer / totalizer also has a fully compliant programmable RS485 MODBUS RTU port for baud rates up to 115 200.
