Oxygen flow meter?

<< < (3/3)

For me it was which unit I found first at the price point I felt was reasonable.  I would have totally sprung for a welding tank - this one just came up first.  I have to say that I love the regulator far more than the welding variety though.

You can get a CGA540 version of the medical regulator, which fits welding tanks.  See the amazon link above.  I use one and it makes it very easy to control the output since it's designed for low flow.

Flow meter is best, but in a pinch you can also use a small ball valve and a sight glass (or the bubbles going through the wort) to gauge the flow. You don't really need a flowmeter.

A quick report on the first use.  It couldn't have been easier.  Set the regulator to 1 liter/minute, stick the aerator wand in the wort, turn the main valve on and start the timer for a minute.  Pull out the wand at 1 minute and shut the main valve.   So glad I found this!
