China Water Flow Switches for Low Pressure System

FSF-100 Plastic Flow Switches with Float Ball
FSF-100 Plastic Flow Switches with Float Ball, This switches is used for low pressure, low fluid speed water system, the switches is made of switches house, float ball and stem of mounting in the pipe.
When the pipe flow is flow the switches house, the float ball rise or down with the pipe liquid level and the reed switches open or close, and putout the switches signal if the pipe liquid flow is up or down.
