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

Great product! Unacceptable service
I have one installed in a housing I made myself, and it has been working perfectly for about a year now.

Documentation sucks
I guess these sensors connect themselves because there is ZERO info on the color code and wiring for NPN or PNP.
No flow data either?????

How does one set the flow at which the device switches?
Thank you for your inquiry. There's a potentiometer on the flow switch which you can use to set the switch point. Full instructions to set a switch point can be found in the manual on page 12.
