If the circuit is constructed as shown above if initially the water in the tank is below minimum threshold and the system is turned on the pump will start pumping water into the tank and no led will come on but immediately water reaches the minimum threshold the red led will come on indicating that the tank is one third full. It has pump running low level high level signals.
Automatic Water Level Controller Detailed Circuit Diagram
Water tank level control circuit diagram. But i have to control the water level in the tank is fixed is water must not out or overflow which is a waste of time look at the pump. Here is a simple level switch circuit that switches on one relay and switches off another relay when the fluid level exceeds the set limitthis circuit is a modification of the simple water level indicator previously postedwhen the water level touches the probes positive supply is connected to the base of q1 through fluidthis makes transistor. Each sensors float is suspended from above using an aluminium rod. This project also work for save water and save electricity. This project is environmental related project. Automatic water pump control circuit help to control water tank overflow.
As a result transistor t1 gets forward biased and starts conducting. It can also be used in fuel level indicator in motor vehicles. If the level of the water reaches high point the pump will started so that the water can be drained and thus lowering the level. Over head tank water level indicator and motor protector. Then we use the water out. When the water level reaches low level then pump will be stopped.
This water level indicator circuit can also be used for a liquid level indicator in huge containers. Such sensors are more reliable than. This arrangement is encased in a pvc pipe and fixed vertically on the inside wall of the water tank. I have the ideal to create this automatic water pump controller project. This is the circuit to determine the level of water in the process tank using relay based onoff control. The low level and high level probes in the overhead tank are marked l and h respectively.
How the operation of relay based onoff control system is. When the water a full tank. The water level is sensed by two floats to operate the switches for controlling the pump motor. When there is enough water in the underground tank probes c and s are connected through water. Automatic water level controller circuit. The a to e wire ends of the circuit are placed in the shown order inside the overhead tank.
You can use up. This panel contains leds to show the status of the water level control. This circuit controls the pump stopped working. The level of the water is indicated by the leds which light up as the water climbs inside the overhead tank. Throughout the above article we have discussed the two methods to design this low cost water level indicator circuit. Water level controller circuit water level controller circuit.
The above circuit has been presented on request from one of my followers prateek. To explain how it operates the images below will show a ladder diagram left side figure and a pictorial diagram right side figure for a visual concept of what happens with.
