Designed for valve monitoring and liquid flow sensing in pipe or tubing, this flow switch provides 3/4 to 1-1/2" (19 mm to 3.8 cm). It has range of 0.04 to 3 FPS (liquids).
Designed for valve monitoring and liquid flow sensing in pipe or tubing, this flow switch provides 3/4 to 1-1/2" (19 mm to 3.8 cm). It has range of 0.04 to 3 FPS (liquids).
OMEGA FST-200 Series 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, 1 to 300 cp, and pulsating flow from 10 to 100 pulses per minute.
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.
