FEC920 Energy Calculator


The SITRANS FEC920 Thermal Energy Meter, the perfect solution for taking back control of your building’s energy costs, provides the real-time data you need to verify your building’s climate control systems are operating efficiently.

With a dual channel system capable of accepting independent thermal energy measurements, the FEC920 works in nearly any application, and with any type of flow meter. Whether monitoring heating, cooling, or condensate systems, with electromagnetic or clamp-on meters, the FEC920 provides revenue grade thermal energy measurements.

The SITRANS FEC920 also communicates via BACnet, Modbus TCP/IP, or EtherNet/IP digital protocols to connect to any building management system.
