Specially designed for heavy-duty professional use for measuring large volumes in chemically aggressive media such as acids, bases & other aqueous media. All parts in contact with the medium are made from highly resistant plastics (PP, ECTFE, ceramic). Thanks to the high-quality ceramic bearings, the 5-blade paddle runs at even very low flow rates & the magnets are hermetically sealed. The contactless sensor system ensures an almost unlimited lifetime. The FCH-SE generates fully conditioned square-wave pulse signals (e.g. for the PLC). By changing the connector an analogue output module can be plugged into a 4-20 m A two-wire system. The two limiting values can be quickly programmed using a teach-in method.
