Level controllers monitor and regulate the filling levels of conductive liquids such as in beverage bottling lines for example. They also distinguish reliably between foam and liquid.

Operating on the conductive measuring principle (conductivity measurement), they monitor all water- containing liquids. For this purpose the resistance between two electrodes inserted into the liquid is used as the measurand. TURCK level controllers feature a large adjustable sensitivity range. Turbulent liquid levels are compensated via switching delay.
