A water flow sensor is installed at the pipe or water source to measure the water flow rate. The sensor can calculate the amount of water that flows through the pipe. The quality of water flow is measured in terms of liters or even cubic meters.

A water flow sensor has a plastic valve through which water passes. Besides, it has a water rotor with a Hall Effect sensor and measures the flow of water. The rotor begins to rotate once water flows through the valve. The speed at which the rotor moves indicates a change in flow rate. The Hall Effect sensor obtains a change in flow output and produces a pulse signal. That shows the quality of water flow.

You will find different water flow sensors with varied flow rate ranges, water pressure, and diameters. It's essential to pick a water flow sensor that covers your needs. Ensure to know how the device works, installation, and maintenance before purchasing. A water flow sensor can be used on dirty, clean, cold, or hot waters.

How to use a water flow sensor

• Obtain breadboard cables and the water flow sensor
• Connect the circuit
• Program your water flow sensor by clicking on the run button
• At the serial monitor, press the connect button to begin serial communication.
• Link your water flow sensor to the tap.

Installing the water flow sensor

• Make sure to install your sensor in a straight section.
• Maintain a minimum of 5diameter pipe behind your water flow sensor and a minimum of 10 diameter pipe upstream
• Eliminate anything that can interfere with the flow within the fitted lengths. It can be reductions or enlargement of pipes, valves, and pipe bends.
• Give access to your water flow sensor by fitting mater pit or valve box over it if t has been installed below grade.
• When your water flow sensor is installed underground, ensure the sensor tee is fitted with the insert located in a straight-up position for easy removal.
• Ensure your water flow sensor is supplied with 48 wire leads.
• You should leave enough loop of wire when splicing leads to the extension cable. That will provide space for sensor insert to come above the ground level for servicing. 

Pros of the water flow sensor

• It guarantees accurate results.
• A water flow sensor is easy to install 
• The change in pressure, viscosity, and temperature doesn't affect its functioning. 

Conclusion

For residential buildings, commercial or industrial plants, you need a large amount of water supply. A public water supply system can meet such a requirement in the best way. Promote proper water usage. It is vital to monitor the volume of water being supplied and used. That's why measuring flow rate becomes critical. A water flow sensor has made everything easy and effective in measuring water flow rate. Ensure to acquire the right water flow sensor. It will help you monitor the flow rate with the highest degree of accuracy.
