Flexim-FLUXUS F721TE Heat and Cold Metering in any Environment

Flexim FLUXUS F721TE Heat and Cold Metering in any Environment

Product Description

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.
