Water Level Pump Controller Circuit

As the water level falls and the top float switch opens current continues to flow through the bottom float switch through the com and no pins and back to the relay coil keeping the relay energized and the pump on. Also this pump controller circuit can be tailored to work as a normal water level controller for a water tank or a cistern. 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.

1 Automatic Water Level Controller Circuit Diagram Electronic Schematics Electrical Projects

The circuit uses 6 transistors 1 ne555 timer ic a relay and few passive components.

Water level pump controller circuit.

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. This circuit is useful to implement in underground rain water harvesting tanks or sewer systems. With a nc normally closed or a no normally open contacts of the relay rl we can handle any type of starter. When you want to use just to turn on the tap at the bottom.

When the water level falls low enough to open the bottom float switch this circuit is interrupted and the pump shuts off. 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. Automatic water pump controller circuit diagram some homes have a large water tank on high then pumping up the put on hold. 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. 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. It does not require all time electricity and also high water pressure. Similarly it gets switched off when the tank is filled up.

Working operation of sump pump controller. Here s a automatic water pump controller circuit that controls the water pump motor. Water level controller circuit this simple water level controller circuit is useful to control the water level in a tank. Built around only one nand gate ic cd4011 the circuit is simple compact and economical.

The motor gets automatically switched on when water in the overhead tank oht falls below the lower limit. Q1 base current is too small less than 1 micro amp. It does this by turning on and off a water pump depending on the status of the sensors. Q1 comes on as soon as water level drops below pump protect.
