Model No: SEN-00043

TK. 479.61

Availability: In stock


Category: Water

Supplier: Made in China

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.
