FS200A YF-G21 Water Flow Sensor 1-30L/min

The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor. It is installed at the water inlet end of the water heater to detect the influent flow rate as it passes through the water flow rotor assembly. The magnetic rotor rotates and the rotational speed changes with the flow rate and the Hall sensor outputs a corresponding pulse. The signal is fed back to the controller, and the controller determines the magnitude of the water flow and performs regulation.

FS200A YF-G21 Water Flow Sensor valve can measure the flow of liquid in the range of  1 to 30 Liter per minutes. This valve operates on 5 to 18V DC voltage with a very minimum current requirement which is between 10 to 15 mA.

Precautions for use:

  1. Severe impact and chemical attack are strictly prohibited.
  2. It is strictly forbidden to throw or collide.
  3. Install the valve input/output according to the direction arrow shown.
  4. The temperature of the medium should not exceed 120 degrees.
