RMS621 Energy manager ©Endress+Hauser

Steam and heat computer for industrial energy calculation of steam and water

The steam and heat computer RMS621 calculates steam mass, steam heat quantity, net steam quantity, steam-heat differential, water heat quantity and water-heat differential in up to 3 simultaneous applications. Bi-directional and splitting range measurements are possible. It supports analog, PFM or pulse signals for flow and pressure sensors. Temperature sensors can be connected in 3- or 4-wire connection or via transmitter. A loop power supply is available for each analog or pulse input.
