Gems Sensors FS-550 Series Paddle Flow Switch for Liquid, 15 gal/min Min, 52 gal/min Max

Standard FS-550 switches sense liquid flow in either direction to monitor flow/no-flow conditions. The paddle is trimmed during installation to permit switch actuation at the desired flow rate. As flow increases, the paddle pivots to move out of the liquid path, producing less than 200 MB 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.

• Engineered for positive liquid flow detection at pressures to 138 bar (2000 psig)

• Compressors
