Beer gas in Denver, set for a mile up
The Brewers Association's Draught Beer Quality Manual gives the rule of thumb: atmospheric pressure drops by about 1 psi for every 2,000 feet of elevation, so add about 1 psi to the regulator setting for every 2,000 feet. In Denver that is roughly 2.5 psi above a sea-level setting.
Miss it and the beer slowly loses carbonation in the keg. Overcorrect it on a long run and you get foam at the faucet. We set the blend and the pressure together, from your line length, rise and cooler temperature, and the TruFusion blender holds a CO2 and nitrogen mix to plus or minus 2 percent.
