It is usually used at the end to detect the amount of input\ncurrent. When the liquid flows through the sensor, A magnetic rotor rotates\nand the rotation rate varies depending on the flow rate.

Sprinkler\nor whatever to manage and control the water flow according to your needs.\nPlease note: A 6mm hose is recommended. Avoid contact with corrosive\nchemicals. The device must be installed vertically and not more than 5\ndegrees inclined. The liquid temperature should be below 120°C to avoid\ndamage to the device. Product features: Min.
