Gems Sensors FS-550 Series Stainless Steel 316 High Pressure Flow Switch, Paddle Type, 15.0-52.0 gpm Flow Setting Adjustment Range, 1" NPT Male

FS-550 Series - High Pressure, Metal Paddle Switch. 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 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 3 PSIG of pressure drop regardless of pipe size.
