Gems FS-550 Series Flow Switch delivers reliable bidirectional liquid flow detection up to 2000 psig with stainless steel or brass construction and patented cam design.
The Gems FS-550 Series Flow Switch provides accurate bidirectional liquid flow detection. It includes two paddle lengths that you can trim during installation to set the actuation point. As liquid flow rises, the paddle pivots out of the path, keeping pressure drop below 3 psig (0.21 bar). The FS-550 handles pressures up to 2000 psig (137.9 bar) and uses a patented cam design that avoids seals, bellows, and linkages. Built with stainless steel or brass, this rugged switch performs reliably in compressors, heat exchangers, turbines, engines, boilers, chillers, valves, pumps, and regulators.
