For monitoring lower flows of corrosive and non-corrosive gases and liquids. Minimal Pressure Drop. When no flow is present the free magnetic piston is suspended in the upper portion of the valve bore due to magnetic repulsion between the lower fixed magnet and the piston. As soon as flow is established the piston is displaced downward and actuates the reed switch at the set point.
Set point is adjustable.
