Gems Sensors FS-550 Series Paddle Flow Switch for Liquid, 52gal/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.

• Engineered for positive liquid flow detection at pressures to 138 bar (2000 psig) ;• Unique, patented cam design assures low-pressure drop and does not require bellows, Seals or mechanical linkages ;• Minimum inline 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
