Our proven fill level measure gauge MFP is now available for monitoring highly corrosive liquids, with a coated probe and non-metallic thread. Appliances of the series MFP work with the principle of guided microwave and achieve a precision of at least 5 mm for all sorts of liquids. These appliances have both PNP switching and analog output. Fill level are displayed in either cm or percentage value. You can program here additional functions such as a fixed offset value or measuring ranges.
