流量和能量计算仪

Configurable Models 1 models
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.

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
