Description

OMEGA™ FST-200 Series flow switches use thermal dispersion technology to create a reliable and economical method of low or no-flow detection of relatively clean, non-coating liquids. Examples include water and acetic acid.

The sensors incorporate two temperature probes, one of which is heated. The flow of liquid reduces the temperature of the heated probe, decreasing the temperature differential with the non-heated probe. These flow sensors are best applied in applications with relatively constant temperature. If the application experiences conditions of pulsing flow then please consider use of the FT-51 or FT-52 fittings - see "To Order" table below.

OMEGA’s LVCN-131 and LVCN-141 of controllers can easily be interfaced to perform a variety of control functions.
