Paddle Type Flow Switch
Flow Switch utilizes the force of liquid flow to propel it’s paddle in order to detect the coming flow or moving liquid or no liquid, the spring is in expanding and press the magnet downward vertically. Reed switch contact is Normally Open (N.O.). As flow occurs and the paddle is pushed and raised at an upward angle of 20 ~ 30 (or more), the eccentric of the paddle will push the magnet upward to actuate the reed switch which is thus in a close circuit. The length of paddle can be adjusted with the diameter of the pipe.
