Gems FS-550 Series Flow Switch

Product Description

The FS-550 Series Flow Switches sense liquid flow in either direction to monitor flow/no-flow conditions. It is engineered for positive liquid flow detection at pressures up to 137.9 bar. The unique; patented cam design assures low pressure drop and does not require bellows; seals; or mechanical linkages. The paddle is trimmed during installation to permit switch actuation at the desired flow rate. As flow increases, the paddle of the switch pivots to move out of the liquid’s path, producing less than 0.21 bar of pressure drop regardless of pipe size. Applications include: compressors, heat exchangers, turbines, engines, boilers, chillers, valves, pumps and regulators.
