Water Flow Sensor

Water flow sensor consists of plastic body, a rotor which rotates when water flows through it and a Hall effect sensor. When water flows through the sensor, the rotor inside the sensor rolls and this speed of rotation changes as the flow rate of water changes. The hall effect sensor inside the water flow sensor senses this rotation and gives pulses as per the speed of rotor.

The Sensor has three wires 

  • Red: Vcc (5V~24V)
  • Black: Ground
  • Yellow: Output which can be interfaced directly to a controller

The output of this water flow rate sensor can be directly interfaced to any microcontroller, arduino & raspberry pi and by measuring the frequency of the pulses you can calculate the flow rate (Liters per Hour). You can also measure the amount of water used by counting the number of pulses. Each pulse is approximately 2.25 milliliters. Note this isn't a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure and sensor orientation. It will need careful calibration if better than 10% precision is required. However, its great for basic measurement tasks!

Specification of Flow Sensor

  • Mini. Wokring Voltage: DC 4.5V
  • Max. Working Current: 15mA(DC 5V)
  • Working Voltage 5V~24V
  • Flow Rate Range: 1~30L/min
  • Load Capacity: ≤10mA(DC 5V)
  • Operating Temperature: ≤80℃
  • Liquid Temperature: ≤120℃
  • Operating Humidity:  35%~90%RH
  • Water Pressure:  ≤2.0MPa
  • Storage Temperature: -25℃~+80℃
  • Storage Humidity: 25%~95%RH

As told earlier the output frequency of flow sensor is proportional to the flow rate. Here is the output frequency of the sensor with respect to the flow rate:

  • 120 L/H : 16.0 hz
  • 240 L/H : 32.5 Hz
  • 360 L/H : 49.3 Hz
  • 480 L/H : 65.5 Hz
  • 500 L/H : 82.0 Hz
  • 620 L/H : 90.2 Hz
Please note there is a 10% error range in the frequency.
