CO2 gas flow detector Answered

Hi all,  I have a 1/4 inch id plastic pipe fed by co2 at very low pressure, normally there is no flow,  but when there is flow (actually suction) I want to to operate a switch that allows flow from the source gas cylinder.  Can anybody help.  A friend can help with making components on a lathe.  Thank you.

Maybe best to go to shop that sells gas amratures and supplies.
they know what's available and suited for your project.
