GIC liquid level controllers are used for various reasons in different settings. Liquid level controllers are used in cars to monitor a variety of liquids like fuel, oil, and other liquids. Electronic water level controllers are also used in industrial tank storages and the most common uses can be seen in homes for electronic water level controllers. An electronic water level controller is basically used to detect the point which is either the maximum or minimum level.
Automatic Water Level Controller Working Principle
A liquid level controller uses a float arm to detect the fluid in the tank. There is a probe set up in the liquid or water tank and the actual devices are located at another place. The probe senses the liquid by coming in contact with it. GIC liquid level controller can be set up to detect the minimum level as well as the maximum level. The specific operations are done and it depends on the type of sensor and controller being used. Electric level controllers are ideal to monitor huge amounts where the temperature is changing. It is also good to probe in conditions where there are good chances of corrosion.
Water level controller with float switch circuit
The moment water recedes below the minimum level, both of the moving contacts from leaf switches should be in the normally closed position. This is going to trigger pin number 2 and it will also reset pin4 which is then connected to the ground. This will activate the connected contacts to the ground. Once the level goes high enough through the driver transistor the pump motor will turn on. The motor starts to pump the liquid in the tank is switched on.
The increased level of liquid shifts the moving contact to a normally open position and activates the connected pins. The water level keeps on rising more and the moment it touches the maximum level, the arm of the sensor brings the moving contact to the normally open position. Once it is done it will get connected to the ground.
The probing sensor is attached to the top and to attach it an aluminum rod should be used. This setup is closed by a plastic pipe and attached vertically inside of the water tank. These types of sensors are way more reliable than any other type of sensor.
Connecting the automatic water level controller with the switch circuit
You can easily connect the sensors with the designed circuit at home. The capacity of the water tank from the top to the bottom water pipe is to be considered because of the time taken for the lowest level sensing unit. The intensity of the water tank from pinnacle to the extent you need the tank to be crammed as much as is taken because of the duration of the most-stage sensing unit.
Each pipe is closed at both ends by using caps. A hollow is drilled in the center of the top cap in order that the aluminum rod can pass through it without problems picking out the touch of leaf switches. Similarly, a hollow is to be drilled at the lowest cap of the pipe in order that water can input the pipe to raise the flow.
When the water reaches the maximum level, the probe moves up higher than the specified distance for pushing the shifting touch of the leaf transfer to the N/O position. Otherwise, the strain at the flow may also destroy the leaf transfer itself. The duration of the aluminum rod is to be decided on accordingly.
Conclusion
The liquid level controller is the best option to monitor and regulate the level of liquids in tanks and for industrial tanks also. It takes the input from the Probe Sensors. Electronic water level controllers are used to detect overflow, and these also work against the dry-running of submerged pumps. The liquid level controller can operate various types of operations like filling and draining the tanks. It has multiple probes to sense and it can be set up for different tasks to be performed at once.
