Measure liquid/water flow for your coffee machine, computer cooling, or gardening project using this handy basic flow meter. This sensor sit in line with your water line, and uses a pinwheel sensor to measure how much liquid has moved through it. Water flow sensor consists of a plastic valve body, a water rotor, and a hall-
effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal, each pulse is approximately 2.25 milliliters. This one is suitable to detect flow in water dispenser or coffee machine.
