Flow Totaliser

Product Details:

Steam 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
• Orifice plate, ISO 5167 computation
• Venturi, Verabar or Annubar This flow computer can easily be interfaced to SCADA or DCS systems with analogue retransmission or RS485-MODBUS outputs.

Multi-parameter display:
• Volumetric flow
• Mass flow
• Steam pressure
• Steam temperature
• Steam density
• Saturation pressure
• Mass total
• Enthalpy
• Specific energy
• Energy flow

Features:
• 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 (analogue 4-20ma) or Superheated steam using both pressure and temperature inputs (analogue 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 is automatically sensed by the Steam Flow Computer, and computations are accordingly processed for Mass Flow
• Isolated RS485 MODBUS RTU port is available as optional for reliable connectivity

Additional Information:

• Item Code: SFC146

Product Details:

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

Multi-parameter Display

• Volumetric Flow
• Mass Flow
• Gas Pressure
• Gas Temperature
• Gas Density
• Compressibility
• Mass Total
• Normalised Flow
• Normalised Total

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.
