DSS All-Metal Flow Switch

Brand: KOBOLD Instruments, Inc.

The KOBOLD flow switches model DSS operate on the suspended float principle, however not with a tapering measuring tube, but with a cylindrical float and a slotted conical nozzle.

This technology allows a very much more compact construction and offers considerable price advantages.
