I stopped by a homebrew supplier yesterday, for a coupler o-ring.
I was looking at the keg hardware, and checked out the regulators. He had a pretty decent selection, including some dual-gauge regulators. I told the guy that when my regulator gives up the ghost, that I'll be purchasing one with a dual-gauge.
He told me to save my money, and buy a single gauge. He explained that the reason is that the gauge displays a constant pressure and is pretty much empty by the time that the reading starts to drop.
Evidently, the CO2 is liquid with a small amount of gas on top. The gas on top is what the gauge measures and the gas pressure remains constant, irregardless of the liquid level, until right before the bottle is completely empty. By the time that the psi drops on the gauge, its too late.
Sounds like it makes more sense to invest money into a spare CO2 bottle.
Thoughts?
