The Flexim FLUXUS G721 CA compressed air flow meter is a non-intrusive clamp-on ultrasonic technology, unique in that it can be applied to measure compressed air flow rates even at very low pressures (down to 3bar on steel lines and atmospheric pressure on plastic lines). Also, even the lowest flow rates are accurately captures revealing the slightest flow rates from the smallest leaks where there should be none. The FLUXUS G721 CA is particularly suitable for non-intrusively Measuring Quantities drawn off at individual points in the compressed air grid as well as detecting leaks within it.
