  • The water flow sensor has a flow range of 2~45 Liter/min
  • It is used to measure the flow rate of water.
  • It consists of a turbine-type rotor that is placed in the water stream.
  • It has a digital output that can be read by a microcontroller or other host device.
  • It is commonly used in applications such as irrigation systems, water treatment plants, and industrial process control.
  • It is easy to install and has a low cost.


The SEN-HZ43WB 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.

Now easily measure water (liquid) flow in your application using this 3/4" Brass water flow sensor. This is a good-quality flow sensor with a brass body and can be used for industrial and commercial applications. These three forth inch water flow sensor is used extensively in various types of vending machines.

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.


  • When magnetic material is close to the sensor, its characteristics may vary.
  • In order to avoid particle debris, the sensor must be installed after a filter.
  • The flow sensor installation has to avoid strong vibration and shaking of the environment, so as not to affect the sensor's measurement accuracy.
