Oxygen flow meter?

[seanppp]

I have read in the Yeast book that for a 1.070 wort you should use oxygenate at 1 liter per minute for 1 minute. Problem is, I can't find an oxygen flow meter anywhere! How am I to know how much oxygen I am putting into the wort?!

Thanks!

See if you can find a rotameter to hook it up to.

I like to use a henway.

About 2 pounds.

Really doesn't matter much, just run it for a minute or more,it will be fine

My numbers on my O2 flow meter don't even start until 2L/min, so I turn it on at just a trickle and let it run for a minute. Works great for me.

I use one of these on my welding O2 tank and just set the flow to 1.5L

Thanks BigFloyd! This looks perfect! Just to be sure, do all O2 connections (welding tank, medical tank, disposable tank from hardware store) use the same fitting?

Nope. The CGA540 connection is for an O2 tank normally used in an ox-acetylene rig.

Hey BigFloyd, I just want to clarify: you use this in place of the standard oxygen regulator - hooked directly to your welding bottle? Or do you connect it to the outlet side of an oxygen regulator?

Direct to the valve on the bottle. No reg.

I answered your PM.

I have one of those, works great, and you can select flow rates with a dial: 1/32, 1/16, 1/8, 1/4, 1/2, 3/4, 1, 1.5, 2, 3, and 4 liters/min. The William's regulator has a 1/4" hose barb for an outlet.

That looks a lot like this one: http://www.amazon.com/dp/B002VWK1GS/?tag=skimlinks_replacement-20

0 to 4 liters per minute. A bit cheaper than Williams but doesn't include the barb.

You could always weigh your tank before and after aeration, if you have a decent balance that will handle the tank. 1 liter of O2 weighs about 1.3 grams.
