While discussing automatic water level controllers, you need to understand that the sole role of this device is to automatically maintain the reservoir or tank’s water level within the range you want. It comprises a control unit with a pump or valve as per the build-up and sensors. You can find the sensors at different levels, which will help you trace the water level.
How does it work?
A pressure switch has a preset option with beginning and ending pressure values. The pump starts automatically whenever the water pressure goes below the set level and off when it goes to the ultimate stopping pressure point.
More about automatic water level controller
The automatic water level controller continuously adjusts the level of the water. Turning the motor on and off as per the requirement is the major work of this device. You can control the wastage of water and energy through it.
Water pumps are inseparable whenever it comes to fluid moments. You can find them in residential water supply processes, HVAC systems, irrigation systems, power plants, industrial processes, and more. Controlling them is important as it adds reliability, sustainability, and efficiency to it.
Commonly, water pumps of four types are there in our surroundings. All four of them comprise pressure control, changing frequency control, and flow control.
Let us discuss the advantages, things to check, and working principles before you stick to any particular control method.
Variable Speed Control
VFD, variable frequency drive technology, or frequency conversion are put to use by different speed water pumps. Variable speed control arrests the pump motor speed while permitting it to perform as per the system’s needs.
Working Principle of Variable Speed Control
If you check this VFD controller, you will find it similar to any microcomputer, capable of handling multiple signals simultaneously. The water pump’s on and off setting completely depends upon pressure sensing. Whenever the frequency decreases below 50hz, the motor functions slowly. You will find the pressure getting stabilized by altering the frequency value. For the places where the water demand is huge, you will get it running quicker and, in the other case, vice versa. When one is not using water, it stops automatically.
Mix the sensor with the module of constant pressure water supply and frequent conversion speed controller so that the water pump works according to the need. This option might look expensive to you compared to the others, but the advantage it adds to your water experience while saving energy and introducing efficiency to the pump is huge.
You will find them in public places or at real estate for controlling the drainage and the water supply.
Pressure and Flow Integrated Control
Check your water booster pump, and who knows, you are using this device. Here, the electronic pressure controls the flow switch and the pressor sensor entirely.
Working Principle of Pressure and Flow Integrated Control
Whenever the tap in this opens, the pump starts and stops the water flow when you close it due to dual control. It is the right substitute for the typical traditional pump, which has a check valve, pressure switch, and pressure tank. It stops working when there is no or less water so it doesn’t get spoiled due to dry running.
The pump in a regular household often stops working due to dry running, and you can stop it with this device. We will not advise using it if you need it for high-pressure applications where several taps run together and the water pressure needs to be changed too frequently.
Pressure Control
It also works on the same phenomenon and starts when it finds the water pressure dropping and stops when it rises. The pressure switch is solely responsible for controlling the pump throughout following this pattern.
Working Principle of Pressure Control
The pressure switch in it is designed in a way that it can easily start and stop the pressure value. The pump turns on on its own whenever the pressure of the water falls below the set pressure and goes off when the water is full. You will find the water pressure changing throughout the day, and a normal unstable pump is not what we advise you. The unwanted on-and-off options may not be what may comfort you in the long run, and you need more than this.
Flow Control
Controlling the flow is the oldest method to control, and with flow control, you will find the pump to start and stop automatically. Surprised! There is a flow switch to do it.
Working principle of flow control
Here, you will find the flow switch to adjust the flow rate automatically. It stops and starts the pump based entirely on the flow rate. It helps to manage the stable water pump flow rate and also controls energy wastage that might occur if you run the pump when not in use. It also reduces water wastage and allows the pump to sustain for a long.
Although a flow switch can be advisable to control the water pump operations in some cases, especially when you cannot avoid a consistent flow rate, sadly, it is not accurate. They are too sensitive towards flow rate changes. You can use them in conjunctions and when paired with other devices only. Use them along with level sensors and pressure switches for the results you are looking for!
Fure of Automatic Water Level Controller
According to Custom Market Insights (CMI), The Global Automatic Water Level Controller Market Size was valued at USD 285 million in 2021 and is estimated to reach USD 487 million by the end of 2030 at a CAGR of approximately 7% during the forecast period 2022-2030.
Wrapping up
While choosing the right pump control method, understand what you need for your application. Check the pump type, pressure, and volume of the water, the set budget, and above all, the water sources.
