Flexim FLUXUS G721 Non-Intrusive Ultrasonic Gas Flow Measurement

The Flexim FLUXUS G721 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of gases. Highly sophisticated signal filters, faster than ever processing capacities and advanced measurement algorithms make the FLUXUS G721 ultrasonic clamp-on 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.
