Black Turbine Water Flow Sensor with 3-Pin JST

The sensor comes with a JST PH 2mm pitch connector and three wires: red (5-15VDC), 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 2.25 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's designed for 1 to 30 Liters/min. It will need careful calibration if better than 10% precision is required. However, it's great for basic measurement tasks.
