Water Flow Sensor Flowmeter Temperature Sensor 1/2”

Description

Water Flow Sensor flowmeter and temperature Sensor is used for water testing and water cooling system. It is solidly constructed and provides a digital pulse each time an amount of water passes through the pipe.

The output can easily be connected to a microcontroller for monitoring water usage and calculating the amount of water remaining in a tank etc.  Mostly applied in water heaters, credit card machines, water vending machine, flow measurement device etc.

It 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. This one is suitable to detect flow in water dispenser or coffee machine.
