The KOBOLD SWK flow meter and switch operates on the suspended float principle, however the design does not use a conical measuring tube. A float 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 and/or an indicated scale mounted on the outside. The SWK series is compact and can be mounted in any orientation. It is ideally suited for monitoring low flows in applications where low cost and high reliability are critical.
