The FSW-25 flow switch utilizes the force of liquid flow to propel its paddle and to detect the incoming flow or movement of the existing liquid in the pipe. In static liquid or no liquid, the spring is in expanded and presses the magnet downward. The reed switch is normally open.
As flow occurs and the paddle is raised at an upward angle of 20 to 30 degrees (or more), the paddle will push the magnet upward to actuate the reed switch which then closes the circuit.
The length of the paddle can be adjusted to the diameter of the pipe. 1" trim size can only be used with metal pipes.
