It is particularly suited to centralised lubrication and to liquids in industrial automation and machinery.\u003c\/p\u003e\u003cp\u003eA magnetic piston on a spring is displaced by the flow, and the magnet closes a reed contact outside the wetted part.

A declaration of conformity is not documented in the datasheet. Before sizing, note: The scale is calibrated in lubricating oil; for other media or temperatures the switching point has to be checked against a known flow. Data block and order code name the housing materials differently (copper or nickel-plated brass).
