The FST-320-Series thermal dispersion flow switches, especially designed for use with gases, sense changes in the heat transfer characteristics of the gases.

The FST-200 flow switches use thermal dispersion technology to create a very accurate and economical method of sensing flow. Monitor fluids from 0.4 to 1.2 specific gravity.

The FSW-6000/7000-Series are thermal flow switch monitors designed to monitor flow status and also used to detect level of liquids, air and gas with visual indication of flow
