Ralph- Most any constant flow regulator will work with the Nelson A4 flowmeter (now produced and sold by Mountain High as the MH4). Pressure delivered is not much of a factor, as long as tubing on the inlet side of the flowmeter is clamped tightly enough to hold against whatever pressure the regulator delivers. I have seen some regulators that have an outlet pressure over 100 psi. Mountain High regulators are normally around 15 psi. I have both in stock. Contact me at: info at mmfabrication dot com

One comment - Absolutely go with using the oxymizer cannula. According to some of my reading you can save 2x to 4x of your O2. Take a look at the two different flow scales on the MH-4 (http://www.mhoxygen.com/portable-constant-flow/79-xcp-mh3-a-mh4-flowmeters-) The long right hand scale is for a standard cannula and the much shorter right hand scale is for the oxymizer.

Sorry, of course I should have said, "The long right hand scale is for a standard cannula and the much shorter left hand scale is for the oxymizer."

I have an Aerox constant flow regulator, with needle valve, pressure gauge, Nelson flowmeter, and moustache style cannula. The regulator is set up with a 4' high pressure inlet line so it can be mounted remote from the O2 bottle. Fits standard Schleicher factory bottle. That setup allows the pilot to reach & adjust the needle valve (which controls flow rate) in flight. It was used lightly as a temporary/removable system in ASW-27/29.

Will trade even and deliver for a good steak dinner & bottle of wine at Reno Convention.
