The RMC621 flow and energy manager uses flow, pressure, temperature and density to calculate the standard volume, mass and energy flow of natural gas and special gases. Depending on the medium, energy values are calculated and expressed using international standards (IAPWSIF97, SGERG88), the real gas equation of state (SRK) or special tables. When measuring differential pressure, the flow compensation factor is calculated over the entire operating range of the flow sensor.
Advantages
Suitable for gases, liquids, steam and water
Up to 3 measurement applications can be calculated simultaneously for different fluids
Process calculations such as density, enthalpy and compressibility are based on equations and built-in material data tables for high precision
Calculation standards: IAPWS-IF 97, SGERG88, AGA8, real gas equation of state (SRK, RK), ISO 5167, tables
Usable with all common flow measuring systems (vortex, turbine, MID, orifice plate, differential pressure, etc.)
Density signal input compensation
Logging function records date and time of error messages and parameter changes
