Helium tank with regulator, to flowmeter, to extension from compressor intake. Plumb helium port partway down intake extension. Now set up a small bleed valve on the output to sample analysis of O2 (with a little math this will tell you what % is He) quickly dial it in & analyze again. When ready send it to the tanks. With a little practice this will become easy. Many are already doing this with O2 on Rix systems (<50% O2), If you have a Rix you can do both gases (not at the same time). We plan on testing this with helium asap (we already know it works with O2).
