You cannot manage what you do not measure, and in heating and cooling loops the number that matters is thermal energy, not just flow. The Flexim FLUXUS F532 TE combines clamp-on flow measurement with temperature inputs and an integrated energy calculator, so it reports thermal power in real time without opening the loop.

Flow is measured on the transit time difference correlation principle, in both directions, on water and water-glycol from 0 to 100 %. The transducers fit inner pipe diameters from 0.39 to 94.5 inch and temperatures from -40 to +266 °F. Temperature measurement and energy calculation follow EN 1434, and the measuring system reaches ±0.3 % MV ±0.02 ft/s for flow, with a calibration certificate traceable to NIST.

The meter is smart meter and IoT ready over Ethernet, with one process interface among Modbus RTU, BACnet MS/TP, HART, Modbus TCP, and BACnet IP, so the data goes straight into a BMS or energy platform. For process liquids beyond water and glycol see the FLUXUS F731, and for compressed air networks the FLUXUS G532 CA.

The FLUXUS F532 TE is available through AV-TEK Consulting in North America. Flexim is part of Emerson. AV-TEK helps you select transducers and temperature probes for your pipe sizes and loop temperatures. Explore more clamp-on flow meters and the full Flexim range.
