Hi,

I picked up a single gauge regulator at a yard sale last week for a buck. The
guy said he used it for welding. It measures in l/min and cfh. It also has 0-6
bar on the dial. What kind of regulator is this? Could it be used for CO2? If
it were broken, what would happen when I tried to use it? Big Thanks In Advance

From what I've heard, the single gauges aren't recomended. People seem to
recommend a double gauge so that you can monitor CO2 output as well as how
much CO2 is left in your bottle.

Hope that helps a bit.

I realize that. But since I had this one I'd see...

As long as there is any liquid CO2 in the bottle, the pressure will be strictly
a function of temperature. The best way to monitor the volume of CO2 in the
bottle is to put it on a scale.

Ahem...
back to my question. Does anyone have an idea?

This doesn't sound like a normal "CO2" regulator. I believe that O2
(Oxygen) regulators have a lefthand thread and most other gasses have a
right hand tread (CO2 for example). By the markings (l/min) it is
clearly some welding specific regulator, but that won't exclude it from
being serviceable as a aquarium CO2 regulator.

The BEST way to identify the usefullness of your regulator is to take it
to a welding supply company and ask them if you could use it for CO2 to
produce 10-20 PSI (I use 20). You'll be visiting the same welding
supply house to get your CO2 refills anyway, and they should be happy to
help you out. You might pretend you're planning on using it for
carbonating and serving homebrew beer, though since they'll identify
with that better than with aquarium use.

Hi
since I posted, I did some more research on it and I think it is a flow
regulator (like a needle valve) vs. a pressure regulator. I will take it by a
welding shop some time. Whatever it's good for, it was worth a $1 gamble

Thank you all
Ben

In that case, if it is marked in l/min, unless it has markings like
0.01, it will be nearly useless for aquaria use. Bummer.
