Gems Sensors & Controls Metal Paddle Flow Switch FS-550 Series

Description
Engineered for Positive Liquid Flow Detection at Pressures to 2000 psig (137.9 bar) Unique, Patented Cam Design Assures Low Pressure Drop and Does not Require Bellows, Seals, or Mechanical Linkages Minimum In-Line Restriction; Paddle Pivots to Move Out of Liquid Path with Increasing Flow Pipe Line Size: 1 1/4" and up Primary Construction Material: Stainless Steel or Brass Setting Type: Fixed 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 (.21 bar) of pressure drop regardless of pipe size. Using Gems™ Safe-Pak® Relays and Barriers, these switches provide automatic flow / no flow interlock and are intrinsically-safe without explosion-proof housing and piping. Applications: Compressors Heat Exchangers Turbines Engine Boilers Chillers Valves Pumps Regulators
