## Description

**Note:** This product previously came with Male 1/4" BSPP threads. It now comes with M11x1.25mm threads.

This water flow sensor consists of a plastic body, a rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rotates. Its speed changes proportionally to the flow rate. The hall-effect sensor outputs the corresponding pulse signal. Typical applications for this sensor include volume measurement in a water dispenser or coffee machine.

 We have a comprehensive line of water flow sensors in different diameters. Check them out to find the one that meets your need most.
