Omar Limited

 * 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
