I am using it from last 3months, have no issues til now
The SEN-HZ21WI water flow sensor is a device that is used to measure the flow rate of water. It consists of a turbine-type rotor that is placed in the water stream, and as the water flows past the rotor, it causes the rotor to spin. The sensor measures the speed of the rotor and converts it to a flow rate. The sensor has a digital output, which means that it provides a digital signal that can be read by a microcontroller or other host device. The sensor is commonly used in applications such as irrigation systems, water treatment plants, and industrial process control.
It can easily measure water (liquid) flow in your application using this 1/2" Brass water flow sensor. This is a good quality flow sensor with a brass body and can be used for industrial and commercial applications. This half-inch water flow sensor is used extensively in various types of vending machines.
The water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rolls, its speed changes with different rates of flow. And the hall-effect sensor outputs the corresponding pulse signal. This water flow sensor is connected in line with the liquid whose flow rate has to be measured. There is a simple rotating wheel with a magnet and when the liquid flows the wheel is rotated and a hall effect sensor measures how many times the wheel is rotated and accordingly gives pulses. By counting the number of pulses you can easily calculate the flow rate as well as the amount of liquid dispensed.
