General information:

A thin elastic diaphragm made of stainless steel, which covers the entire flow cross-section, is deflected by the flowing fluid, and thereby attaches to an arched stop (therefore, overexpansion cannot occur!).

There is a plastic-coated magnet on the diaphragm. When there is a deflection, its magnetic field changes, which is detected by a sensor outside the area of flow.

As the diaphragm simply bends and does not operate with a bearing, there is almost no frictional effect and extremely little wear. The movement occurs practically free of hysteresis, and the measurement results have a very good reproducibility. The diaphragm's low mass results in a rapid response time. The almost complete covering of the flow cross-section in the neutral position enables a very low metering range start value.

The evaluation of the entire flow cross-section enables a problem-free pipeline routing. Run-in and run-out sections are not necessary. Due to the shaped stop and the elastic properties of the diaphragm, even severe water hammers do not cause any damage. The low number of parts coming into contact with the medium as well as the bending of the diaphragm guarantee a low tendency towards soiling and material adhesion. The flange construction simplifies installation and service.
