I have tanks at different pressures of CO2 and methane. I want to mix them through flow regulators (not pressure regulators) in various proportions. The flow regulators are simple "calibrated bead in tube" type (called "Flow Raters" manufactured by Dwyer). If flow from both tanks is maintained at some level is it possible for gas from the higher-pressure container to enter (backwards through the other 'flow rater') the lower-pressure container? Pressure in both cylinders is similar, but not identical. I would establish flow from the low pressure cylinder first, then the high-pressure cylinder, and shut off the high pressure cylinder first. Again, I can regulate flow rate (in scfh) well enough for my purposes, but have no way of regulating pressure.

Buy a Japanese car. They never do this. Seriously, if you can get to the gas tank to bang on it, you may see if it "feels" full. Second, I would push the fill flap out of the way with a screwdriver and shine a flashlight down there to try to see gas. You probably won't be able to see far, as there is usually a baffle, but you may see gas if full. I'm sure you could sweet talk a man into these tasks so that you don't get yourself dirty. You may also try a full-service gas station (if they exist where you are) or a local parts place like Auto Zone to have a guy look at it. Good luck, hope you don't get stranded.
