The sensor comes with three wires: red (5-18VDC power), black (ground) and yellow (Hall effect pulse output). By counting the pulses from the output of the sensor, you can easily track fluid movement: each pulse is approximately 2 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!
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.
