Flexim FLUXUS G631 Leak Detection Instrument Portable Non-Intrusive Clamp-on Ultrasonic Flow Meter
Flexim FLUXUS G631 Portable Ultrasonic Clamp-On Flow Meter
The FLUXUS G631 from Flexim is a versatile portable clamp-on ultrasonic flowmeter for gases and liquids. It enables accurate, non-intrusive flow measurement by mounting transducers externally on the pipe wall, eliminating the need for process shutdown or pipe modifications.
Product Overview
Based on the transit-time ultrasonic principle, the G631 delivers reliable bidirectional readings for a wide range of acoustically conductive media. It incorporates functions such as Dynamic Gas Meter calculation, disturbance correction for constrained installations, and diagnostic tools that indicate measurement stability. Battery-powered operation supports both short-term surveys and extended monitoring in Energy Saver Mode. The dual-channel design and advanced signal processing enhance performance in challenging conditions.
