gas flow switch
(OP)
Is there some sort of switch that connects in-line on a gas flow that when the flow reaches a lower flow leval that it sends a signal to a valve on a diffrent line that will swicth that flow either off or redirect it.

RE: gas flow switch
There are ton of flow and pressure switches out there. Do a search on the web, or if you have a buyers guide start there. I'm sure that there are even a few in Graingers. Good luck.
RE: gas flow switch
1)requires fairly constant gas specific heat ratio(cp/cv) i.e wide variations in hydrogen concentration will cause the calibrated range to shift.
2)gas is fairly clean.
To hook-up the flow switch to your valve (on/off valve, solenoid operated) should be a simple exercise.
Typical vendor would be FCI, but there several other vendors.
Good luck..!
