Overview

This Hall Effect Water Flow Meter Sensor incorporates a pin wheel sensor and fits inline with a hose or pipe and measures the amount of liquid that has flown through it. It integrates a sealed magnetic hall effect ensor outputs an electrical pulse with every revolution. Its also sealed from the water pipe and allows the sensor to stay safe and dry.

The YF-S201 Hall Effect Water Flow Meter Sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output).
By counting the pulses from the output of the sensor, you can easily calculate water flow. Each pulse is approximately 2.25 milliliters.

Please 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.
