Kobold SWK Variable Area Flow Meter Low Volume

Kobold SWK Variable Area Flow Meter Low Volume operate on the known suspended float principle, however without using the generally known conical measuring tube. An orifice 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 a floating sealed contact (reed contact) mounted on the outside. The instruments are small and can be mounted in any orientation. Model SWK flow switches are ideally suited for monitoring low flows.
