Flexim FLUXUS G631 BA ST EE Portable Clamp-on Ultrasonic Flow Meter Gases Liquids Steam Flowmeter

The Flexim FLUXUS G631 is a portable transit-time ultrasonic flow meter designed for non-intrusive measurement of gases and liquids. Clamp-on transducers mount on the outside of the pipe, allowing accurate flow readings without process interruption, pipe cutting, or pressure loss.

This instrument uses the proven transit-time correlation principle to measure virtually any acoustically conductive gas or liquid. It supports bidirectional flow measurement of operational and standard volume flows. Key capabilities include gas measurement down to low pressures, flow disturbance correction for short inlet conditions, advanced diagnostics for measurement quality, and NoiseTrek mode for fluids with impurities. The portable design offers extended battery operation for temporary surveys, verification, and energy assessments.

Used in oil and gas, chemical processing, power generation, life sciences, marine, water and wastewater, and general industrial facilities for temporary flow measurement, verification, leak detection, energy monitoring, and condition assessment.

Users often face challenges with process downtime for meter installation, pressure loss from inline devices, or limited capability to measure both gases and liquids with one portable unit. The FLUXUS G631 addresses these through fully non-intrusive clamp-on technology and multi-media measurement capability.

Suitable as a modern portable alternative or upgrade for earlier Flexim FLUXUS portable series meters and other clamp-on ultrasonic flowmeters used for temporary or verification measurements.
