Water Level Pump Controller Circuit

With a nc normally closed or a no normally open contacts of the relay rl we can handle any type of starter.

Water level pump controller circuit.

Nowadays all the householders owners are storing the water in overhead tanks by using the pumps. The circuit formed by transistors q1 and q2 is designed to turn on the red led pump protect whenever there is no water between pump protect electrode and ground electrode at pump reservoir. Here s a automatic water pump controller circuit that controls the water pump motor. It does not require all time electricity and also high water pressure.

The water level controller circuit is a simple mechanism to detect and control the level of water in the overhead tank and also in the other containers. Similarly it gets switched off when the tank is filled up. This circuit is useful to implement in underground rain water harvesting tanks or sewer systems. Working operation of sump pump controller.

When you want to use just to turn on the tap at the bottom. It does this by turning on and off a water pump depending on the status of the sensors. The motor gets automatically switched on when water in the overhead tank oht falls below the lower limit. Also this pump controller circuit can be tailored to work as a normal water level controller for a water tank or a cistern.

The circuit is completely automatic which starts the pump motor when the water level in the over head tank goes below a preset level and switches off the pump when the water level in the over head tank goes above the full level. Built around only one nand gate ic cd4011 the circuit is simple compact and economical. Approx aluminium rods push the moving contacts p1 and p2 of leaf switches s1 and s2 from normally closed n c position to normally open n o position. Q1 base current is too small less than 1 micro amp.

The circuit uses 6 transistors 1 ne555 timer ic a relay and few passive components. Automatic water pump controller circuit diagram some homes have a large water tank on high then pumping up the put on hold. Automatic water level controller circuit leaf switches s1 and s2 used in tape recorders are fixed at the top of the sensor units such that when the floats are lifted the attached 5mm dia. Q1 comes on as soon as water level drops below pump protect.

Water level controller circuit this simple water level controller circuit is useful to control the water level in a tank.
