The Flexim FLUXUS F721TE is specially designed for heating and cooling Thermal Energy measurement, with all measurements - Flowmeter, Temperature, and BTU computer, contained in one device. Calculations are done in accordance with EN 1434 Thermal Energy meter standard and the F721TE measures the volumetric flow rate non-intrusively via its clamp-on ultrasonic transducers. Simultaneously, temperature probes monitor the temperatures at the supply and return lines of the heating or cooling system - either non-intrusively with clamp-on sensors or by use of insertion temperature probes. It can be equipped with two measurement channels to measure two pipes simultaneously and allow complete monitoring and accurate measurements.
