Measure Mass Flow of Gases

High Reliability, No Moving Parts

Effectively Monitor Critical Gas Flows

May Be Used in Small Piping or Large Ducts

1 AMP SPST Relay Standard

OMEGA’s FST-320 Series thermal dispersion flow switches, especially designed for use with gases, sense changes in the heat transfer characteristics of the gases. Flow velocities from 1 to 90 fps are effectively monitored. The flow switch incorporates a standard SPST Relay switch output for control flexibility. The OMEGA? LVCN-131 and LVCN-141 controllers can easily be interfaced to perform a variety of control functions. The FST-320 family of sensors can be easily installed in line sizes ranging from 3/4 to 12".
