Flexim-FLUXUS F532 Thermal Energy Non-Intrusive Heat Cold Meter

Flexim FLUXUS F532 Thermal Energy Non-Intrusive Heat and Cold Metering

Product Description

The Flexim FLUXUS F532 TE is a compact thermal energy meter with integrated heat flow calculation for water and all water-glycol mixtures. The FLUXUS F532 Thermal Energy is specially designed for heating and cooling measurements in industry and building applications. Based on the established transit time difference method, the volume flow is measured non-intrusively with ultrasound, and the supply and return temperatures are registered via 2 temperature inputs. Totalizers for total thermal energy are also included. Offering USB and LAN interfaces and serves the common communication interfaces Modbus TCP, Modbus RTU, BACnet MS/TP, BACnet IP and M-Bus.
