Like day_trippr said, the tanks will both empty at the same rate and you'll be left with 2 empty tanks.

If you want this to work, you need a secondary regulator. Set the primaries at two different pressures (say 30 psi and 25 psi), then adjust down to your desired pressure using the secondary. The 30 psi tank will empty first, then the 25 psi tank. I do this all the time in the lab to prevent experiments from shutting down while I change a tank.

+1 on all of this. I used to have to do the same thing at work. No we have a tank switcher, which is AWESOME.

I knew that someone with a scientific backround would be able to answer this. Thanks!

In academic research, even "paid" is a relative term.

As long as you do not have any leaks and the sitter doesn't drink your beer, I fail to understand how the kegs would lose pressure or beer?

I've been presuming this was all aimed at a carbonation system, so if the system ran out of gas the attached keg(s) would stop carbing up.

Why this seems to be a big enough problem to need a solution escapes me, however...

Cheers!
