To achieve the automatic control of water tower and water level,probes B and D are put in well. Under normal circumstances, it should be in a certain depth of water level. It makes the output terminal 3 of IC2(555) circuit turn to low level, J2 pull-in, J2-2 closed. Pumping continuously makes polar B and polar D expose from water, pin 2 turn to a low level. It makes IC2 turn-over position, pin3 turn to a high level, J2 release, J2-2 disconnect to avoid motor from idle running, then it willmonitor the water level of the well.
