Description

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 0.3 to 27 metres/sec 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".
