Automatic Water Level Controller for Motor Pump Complete 100% Review

Automatic water level controller – Searching to know what is water level controller?? You have come up in correct place.

A water level controller automatically stops the water motor when the water tanks go above the maximum water level. And not only for this, but it also automatically starts the engine when water in the tank goes below the water level.

This device senses the water level by two floats and switches on/off when required.

Many peoples use automatic water controllers at their homes, and also it is used in many hotels because it gives convenience that you don’t need to turn on/off when water goes down or up.

I will tell you about automatic water pump controller, its circuit, and construction, and I’ll let you know about some devices in today’s article. water level controller

Also you will learn about how automatic water level controller work and some good water level controller, about water level sensor and many more. Keep reading

 Automatic Water Level Controller Circuit

Automatic Water Level Controller for Motor Pump Complete 100% Review

The arrangements of an automatic water controller circuit are encased in a PVC pipe. And that covered PVC pipe is fixed inside the wall of the water tank vertically. water tank level indicator

Well, there is a reason why the circuit is fixed vertically. Just because it is fixed vertically, sensor 1 touches the maximum level point, and sensor 2 touches the minimum level point. This will help to recognize the water level in the tank.

The leaf switches, mainly used in tape recorders, are fixed at the circuit’s top sensors. So that when the water flows above the maximum point, the aluminum rod push P1 and P2 contacts of leaf switches S1 and S2 to N/O position.

These contacts are generally in N/C means in the closed position, but contacts push it to N/O means open position after water flow. automatic water pump controller

S1 contact of N/C is connected to the ground while the S2 connection of N/c is connected to the 12 V power supply.

Well, this is the normal thing in a circuit. But in IC 555, the pin two trigger is attached in the ground, and it will get triggered, and when you connect pin four in-ground, it resets. water tank level indicator

Automatic Water Level Controller Circuit Operations

When the water in the tank goes below the minimum level of water, the P1 and P2, which are moving contacts, both these leaf switches go in the N/C position. The N/C position indicates that pin2 triggers and resets of IC1 12V are connected to the ground. Then the water motor will be on and start filling water in the tank. automatic water pump controller

The second case is what the circuit does when the tank’s water goes above the maximum water level.

As the water in the tank goes above the top level, the first sensor goes up. Because of this, the moving contact switches its position to N/O.

Then sensor two also pushes the moving S2 contact and changes its position from N/C to N/O, and it gets connected to the ground. And because of this, the water motor switches off.

And the third case is when the water in the tank is sufficient, then what the circuit does? So in that condition, point the point P1 and P2 are closed through water and kept and kept S1 in on state. water level controller

Which further helps in switching off the water motor when the water reaches the maximum level.

So these are the three conditions or cases where an Automatic Water level controller circuit works. All the things are very much comfortable to understand. The circuit switches off the water pump when water goes above the maximum level. And switch on the water motor when the water in the tank goes below the minimum level.

It makes the work easier that we don’t need to manually switch on and off the water motor, all the things the circuit will do automatically. water tank level indicator

Construction of Automatic Water Level Controller

Now, let’s discuss the construction or installation of automatic water level controller.

You can quickly self assemble the float sensor units at home. Jut the length of the units is different. So, you have first to identify that carefully; otherwise, all the things are easy to do.

You have to fit both the sensor inside the water tank. Sensor 1 at the top, attach it to that point you want to set as the maximum point. And attach sensor two inside the water tank at the bottom, set it also at that point which you want to set as minimum water level point.

And then, after set the leaf switches at the top of the water tank. Then set the pipe and cover it both ends with a cap. And to pass the aluminum rod, you have to drill a hole on the tank and connect it to leaf switches.

You have to drill a hole at the bottom and connect the pipe to contact leaf switches after all these things. You have to test your automatic water pump controller by giving the electric supply to the circuit.

If the tank does not contain water, the water motor will start automatically, and it will fill water in the tank up to the maximum point.

Well, for installation, you must have to hire experts. Because to connect water motor and all the things you must need experts. water tank level indicator

Because for installation, you also need a drilling machine to make a hole in the water tank of the pipe size. And to attach leaf switches and sensors on top and bottom, you require some instrument which only experts have.

After the whole installation, you have to give an electricity connection to the automatic water pump controller circuit. And then it will do all the things.
