FLEXIM FLUXUS F731 Clamp-On Ultrasonic Flow Meter with Non-Intrusive Flow Measurement and Bidirectional Capability for Wide Pipe Size Range
The Flexim FLUXUS F731 is a high-performance clamp-on ultrasonic flowmeter for permanent liquid measurement. It delivers accurate volumetric and mass flow data without contact with the process fluid.
Transducers are clamped onto the outside of the pipe, allowing installation without shutting down the process or modifying the piping. The meter incorporates advanced algorithms, including Synchronised Channel Averaging and flow profile correction, to handle difficult hydraulic conditions. It offers excellent zero-point stability, bidirectional capability, and support for a wide range of pipe diameters and industrial fluids. Optional dual-channel operation and multiple communication protocols facilitate flexible system integration.

Widely used across chemical, petrochemical, oil & gas, water/wastewater, pharmaceutical, and general manufacturing sectors for non-intrusive process flow measurement.
Issues such as pressure drop from in-line meters, installation downtime, or sensitivity to pipe conditions are minimized by the external clamp-on design and advanced compensation features of the F731.
Serves as a capable upgrade or alternative to previous Flexim series meters and other non-intrusive or conventional liquid flow instruments.
