The is an automatic water supply and drainage Level Controller ideal for level control of any conductive liquid. The conductive type level controller consists of a plug-in controller connected to a set of stainless steel probes and is cut to length and inserted vertically into the liquid. A low voltage is applied between these probes and the earth probe or tank, if it is electrically conductive. The water provides a current between the earth probe and the high-level probe. The output relay in the controller is energized when the water level reaches the high-level probe and de-energized when the water level falls below it. For two-point control a low-level probe is used as well. In this case the relay does not de-energize until the water level falls below the low-level probe. Using the low-level probe allows a wide differential between switching a pump on and off and can avoid excessive pump operation during tank emptying or filling.
