Available for conductive liquid like Water and for non conductive liquids like Diesel Oil etc. Level controllers for conductive liquids are supplied with or without stainless steel electrodes. Various models are available, for single level and two level control (WLCD1 / P1 LCW1) & two level & two tank control (P2 LCW1). Level controllers for non conductive liquids are supplied with photo sensor and are suitable for one level (DLC D1 + FRK P1) or (FRK P2 sensor with Open Collector). ILM D1 finds application for seal monitoring and leakage detection in submersible pumps.
