Flexim Fluxus G721 Clamp on Ultrasonic Flow meter For Gas

General Information

The FLUXUS G721 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of gases. With its state-of-the-art hardware design and powerful digital signal processing, it surpasses any other non-intrusive ultrasonic gas flowmeter in terms of accuracy, reliability, and versatility.

Flexim- Fluxus G721 Setting Standards in Clamp-on Ultrasonic

Highly sophisticated signal filters, faster than ever processing capacities and advanced measurement algorithms make the FLUXUS G721 gas flow meter the standard-setting measuring solution for any industrial application – even for the most challenging ones.

The meter adapts itself automatically to the respective measurement conditions and compensates for flow profile disturbances such as beam dispersal and structure-borne noise, allowing for even more precise and reliable measurements. Extreme fast measurement cycles enable precise real-time monitoring of highly dynamic processes.
