Field of application

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.
