De­signed with a single or dual channel system capable of ac­cepting a wide range of flow and temperature measure­ments, the FEC920 works in nearly any application. Whether measuring heating, cooling, or condensate systems with new or existing flow meters installed, the FEC920 provides rev­enue grade thermal energy measurements and can connect to any building management system.


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