Steam calculator for recording steam mass and energy flow for saturated or superheated steam

The steam calculator EngyCal RS33 is used to record steam mass and energy flow of saturated and superheated steam. The calculation is based on the measured process variables volume flow, temperature and/or pressure.
The EngyCal RS33 uses the standard IAPWS IF97 to calculate the mass and energy flow of steam. The density and enthalpy of the steam are calculated from the input variables pressure and temperature.

  • Benefits

    • Compensation of differential pressure flow measurement

    • Calculation according to international water steam tables

    • Electronic matching of the temperature sensor (sensor-transmitter matching) with the arithmetic unit enables highly accurate temperature...

  • Field of application
