mine is a full sized one from a welding setup for shielding gas. it is rated in CuFt/min so it is an actualy flow meter not a pressure regulator.
sounds like a small differance but depending on your set up a pressure regulator (which is what is used on most CO2 reactors) will let in more or less CO2 as long as the pressure is the same, causing your bubble count to change. all it take to change this is a little change in the internal pressure of the reactor or even water evaporating out of the bubbler.
with mine it couldn't care what the pressure is as it will always let the same volume/time into the reactor so I get no changes. you can get a cheep flow meter for about 100 bucks but the deicent ones start at 200 and up.
I also made both chambers in my reactor upflow which got rid of the problems Tony was mentioning.
