Steam Flow Computer
Flow computer SFC-146 is designed for Steam Mass Flow measurement.This versatile flow meter computes compensated steam flow receiving input from
- Vortex flow meter, from volumetric flow
- Orifice plate, ISO 5167 computation
- Venturi & Verabar computations.
This flow computer can easily be interfaced to SCADA or DCS systems as various options like analog retransmission and RS485-MODBUS outputs are available.
Salient features
Multi-parameter display
- volumetric flow
- mass flow
- steam pressure
- steam temperature
- steam density
- saturation pressure
- mass total
- enthalpy
- specific energy
- energy flow
Built-in steam table IAPWS-1997 algorithm, real-time calculation of compensated mass flow and other steam parameters.
- saturated steam using pressure or temperature inputs (analog 4-20ma).
- superheated steam using both pressure and temperature inputs (analog 4-20ma).
Preset temperature or pressure values can be programmed in case on-line signals are not available or transmitter failure.
Saturated or superheated steam can be selected from an option menu, and there is a warning when no superheat is present in the steam.
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.
Isolated retransmission 4-20ma analog output signal.
Isolated RS485 MODBUS communication for reliable connectivity.
