    That's good news. Looks like the gauge is a pressure gauge, but displaying flow rate for some specific application (where the flow never stops), assuming some constant line resistance. If you knew what that was, you might be able to just use it as is, maybe making a few marks on the face for PSI. Where did this regulator come from, anyway? Also, do you have a bottled gas supplier (other than a beer distributor) in your area? They might recognize it and be able to tell you how to convert the dial readings to PSI.

    It sounds like the sort of display that could be useful for running a gas chromatograph, so that the the flow rate of the carrier gas is displayed. However, in my GC days, my regulator read in pressure unit. I measured flow rates manual with a bubble meter and a stop watch. Archaic technique.

    I have an AirGas and other industial gas spots in town. I can take it there tomorrow.
