Measure the flow rate of a liquid or del' water has never been easier with this sensor. This sensor is mounted in series of your installation and uses a sensor to propeller. The propeller has a small magnet mounted on it, and a magnetic hall effect sensor will measure the number of turns to deduce flow. This method is simple, effective and especially waterproof.
The sensor has three sons: red for power supply between 5 v and 24 V DC, black for the mass and the yellow for the signal (pulse). Relying on the signal output peaks, it is easy to deduce ele flow, each peak is about 2.25 ml. Beware, it is not a precision sensor and peaks may vary slightly depending on the speed, the type of liquid and orientation. It will require a calibration process, if you want to get a precision of less than 10%.
