Product Details

Description


This high accuracy hall flow meter sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There's an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.


By counting the pulses from the output of the sensor, you can easily calculate water flow. Each 400 pulses is approximately 500 ml/min. 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 2% precision is required. However, its great for basic measurement tasks!
