Flow Meters and Switches of model SWK operate on the known suspended float principle, however without the use of a conical measuring tube.  A float with orifice moves in the direction of flow against the force of a spring in a cylindrical guide tube.  The float contains a permanent magnet which operates an adjustable setpoint contact mounted on the outside.The SWK series is compact and can be mounted in any orientation.  Model SWK flow switches are ideally suited for monitoring low flows in applications where low cost and high reliability are critical.
