  • ©Endress+Hauser
  • ©Endress+Hauser

The flow and energy manager RMC621 calculates standard volume as well as mass and energy flows of natural and technical gases, fluids and steam from flow, pressure, temperature and density. Depending on the medium calculation of the energy values occurs according to international standards (IAPWSIF97, SGERG88), real gas equations (SRK) or specific tables. For differential pressure measurements coefficients for flow compensation are calculated over the complete operating range of the flow sensor.


  • Suitable for applications with gas, liquid, steam and water

  • Simultaneous calculation of up to 3 measuring applications, even if different fluids are used

  • Very precise process calculations (density, enthalpy, compressibility) on the basis of equations and/or storable tables with material data

  • Calculation standards: IAPWS-IF 97, SGERG88, AGA8, real gas equations (SRK, RK), ISO 5167, tables

  • Can be used with all common flow measuring systems (vortex, turbine, MID, orifice plate, differential pressure, etc.)

  • Compensation input for density signal

  • Logbook function for error messages and parameter changes with date and time
