Abstract

PURPOSE: To prevent a trouble due to an invading extraneous substance, by starting a pump by a water level detector which acts at an upper water level and by stopping the pump by an electrical current detection relay which detects a load decrease due to the fall in the level of water.
CONSTITUTION: When the level of water rises to L1, a float switch 4 as a water level detector is turned on to start a pump 1. When the water level falls to L0, an electrical current detection relay R is turned off to stop the pump 1. Automatic operation is repeated between the upper and the lower water levels L1, L0. A ground pump may be used so that the front end opening of a water suction pipe is located at the lower water level. The float switch 4 as the water level detector is hung down into a vessel so that no troubles occure even if many extraneous matters invade into the vessel and a liquid surface in particular. The float switch is thus prevented from performing erroneous action.
