Product Description

The Flexim FLUXUS F721 WD non-intrusive ultrasonic flow meter is the perfect flow measurement solution for drinking water and wastewater applications. It enables a very simple and cost-effective clamp-on installation of flow measurement points within an existing water supply and wastewater infrastructure. The Flexim FLUXUS F721 WD belongs to the most reliable and accurate non-intrusive ultrasonic flow metering systems. It even measures flow velocities as low as 0.01 m/s (0.03 ft/s) – ideal for leak detection and night flow measurements. Thanks to permanent coupling of the transducers onto the pipe and the IP68 protection, it is suitable for installations in chambers and for buried or flooded installations. Compared to the F532 WD, the F721 WD serves pipes with diameters of over 2000 mm (79 in), offers dual channel measurements and comprehensive communication combinations.
