Gems FS-550 Flow Switch

Gems^® type FS-550 high pressure, metal paddle switches sense liquid flow in either direction to monitor flow/no-flow conditions. They are supplied in two paddle lengths. The paddle is trimmed during installation to permit switch actuation at the desired flow rate. As flow increases in a pipe, the paddle of the switch pivots to move out of the liquid path, producing less than 3psig of pressure drop regardless of pipe size.
