The Flexim FLUXUS G731 CA is a specialized clamp-on ultrasonic flow meter designed for precise, non-intrusive measurement of compressed air flow—even at extremely low pressures. Its advanced technology allows accurate monitoring on steel pipes down to 3 bar and even at atmospheric pressure when used on plastic piping.

This innovative system is capable of detecting minimal flow rates, making it highly effective for identifying small leaks and optimizing air usage. The G731 CA is especially well-suited for monitoring consumption at individual take-off points within a compressed air distribution network, as well as for leak detection and efficiency analysis across the system.

By eliminating the need to cut into piping, the meter provides a seamless, maintenance-free installation with no disruption to ongoing operations—ideal for facilities aiming to improve compressed air efficiency while reducing operational costs.
