Gelco automatic liquid level controller has been designed to have automatic operation of motor pump set depending upon the level of liquid in underground as well as overhead tanks. When the water reaches below set low level in overhead tank, the unit switches on the motor pump set automatically and similarly switches it off when the water level reaches a set high level in the tank. The system also ensures that if there is no water in the underground tank, the pump will not switch on even if the overhead tank is empty, thus preventing the motor pump set from dry running. Three models are available to suit motors of single phase and 3-phase versions in different hp ratings. Special magnetic sensors can be used for non-conductive liquids.
