How Water Flow Sensors work and what are their Applications?

Sensors are very useful devices used in water control systems. They come in very compact and handy sizes. These are also available in various kinds depending upon the purpose. With the evolution in technology, they have become more and more compact in size and specifications. They are used for many types of applications, such as finding the ambient light, measuring the temperature and pressure.

A perfect management of water includes an accurate supply of water as required in the processing and other activities. Water supply is a very crucial process in water management. To achieve this purpose, water flow sensors play a vital role. The main benefit of a water flow sensor is that it can tell the accurate rate of flow of a particular liquid with detailed information. Read the full article to know more about their working principle and applications that they have. Also, you will come to know how they will benefit your industry if installed in a correct way.

Working Principle

The water flow sensor contains a valve made of plastic. The water, the whole flow is to be measured, flows through the plastic valve. It also contains a Hall-effect sensor and a rotor, which helps to measure the flow of water.

The water flows through the channel, passes through the valve, and it makes the rotor rotate. With the rotation of the rotor, it sends a signal to the sensor, and the change in the speed of the rotation is determined. The signal is then decoded into the numerical data.

A water flow sensor is based on the principle of hall-Effect. According to it, an emf is introduced in the conductor when the rotor rotates. In this way, the emf produced is transformed into a signal that tells the exact rate of flow of the liquid. The rate of the fluid flow is displayed on the LCD screen in digits.

These water flow sensors can be easily used for cold and hot waters, dirty and thick fluids, and more. Depending on the machine and structure, these are available in various diameters. These are placed at the inlet and outlet of the pipe and channels.

Their Applications

Water flow sensors operate by measuring the velocity or displacement of the fluid. The paddlewheel flow sensor is one of the most common flow sensors that are cost-effective and easy to use. The positive displacement flow meter can be used if the tube or channel is bent shaped and a normal flow meter can not be inserted. If the liquid is viscous, then there are certain types of special flow meters that can be used for that purpose. For dirty and filthy liquids, magnetic flow sensors are the best.

Conclusion

In this way, we see that a water flow sensor is a useful device for every type of industry. If you require a flow sensor, too, then it is advised you do proper research to find the best one for your requirement. Water flow sensors come in several specifications and diameters, and you have to look for the perfect one.
