Water Flow Meter - Plastic 1/2"

This Water Flow Meter - Plastic 1/2" or Water Flow Sensor measures the rate of flow by counting how many times the wheel has spun, via a hall effect sensor, each pulse is approximately 2.25 mL, note that this isn't a precision sensor, and the pulse rate will vary slightly depending on the flow rate, fluid pressure and sensor orientation. The water flow meter sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output). To use this sensor you will need a controller such as an Arduino to count the pulses, and an LCD to display the values.

We have an example Arduino sketch that can be used to quickly test the sensor - it will calculate the approximate quantity of fluid in liters and display on an LCD or the serial monitor.
