When the water level doesn’t reach the certain level, the circuit doesn’t work. When there is water in inlet pipe, VL1,VL2’s negative poles will have low level, which will make V1 disconnected and V2 connected. K is connected and YV begins to work, adding water into the water tank.. Then VL2 is illuminated. When the water reaches a certain level, V1 is connected, and V2 is disconnected. K is released, and YV is disconnected. Then water supply is stopped. At the same time, VL1 is illuminated. If there is no water in the inlet pipe, VL2,VL1’s negative poles will have high level, making V1,V2 disconnected, and K, YV don’t work.
