FS-550 HIGH PRESURE PADDLE FLOW SWITCH

Designed for installation in pipe lines from 1-1/4” and up, Gems standard FS-550 switches sense liquid flow in either direction to monitor flow/no-flow conditions. They are supplied in two paddle lengths, the paddle being 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 3 PSIG of pressure drop regardless of pipe size.
