Overview

The FLUXUS F532 Thermal Energy is specially designed for heating and cooling measurements in industry and building applications. The new 532 platform allows for best FLEXIM performance, measurement accuracy and modern interfaces.

FLUXUS F532 TE is a compact thermal energy meter with integrated heat flow calculation for water and all water-glycol mixtures.

Based on the established transit time difference method, the volume flow is measured non-invasively with ultrasound, and the supply and return temperatures are registered via 2 temperature inputs.

The heat flow calculated in this way is determined highly dynamically and with a fast response time. Of course, totalizers for total thermal energy are also included.

FLUXUS F532 TE has USB and LAN interfaces and serves the common communication interfaces Modbus TCP, Modbus RTU, BACnet MS/TP, BACnet IP and M-Bus.

100% FLEXIM performance of course also means availability of important features:

  • Advanced Meter Verification – diagnosis and verification of installed measurement points with FluxDiag software
  • Distrubance Correction – automatic correction of interference sources such as 90°C arcs
  • Aperture Calibration – FLEXIM's patented, high-precision calibration system for all ultrasonic sensors
  • Accuracy in flow: 1% b.w.m. +-0.005 m/s

This makes the FLUXUS F532 TE not only usable as a thermal energy meter, but also for monitoring processes and plants.

As a non-invasive measuring system, it not only brings the advantage of uninterrupted installation with little effort – above all, it significantly reduces the total cost of operation. Maintenance-free, wear-free and at any time without disturbing the process.
