Is Williams brewing still the best oxygenation system?

[twd000]

A couple years ago I had researched the oxygenation systems but never pulled the trigger. I have the disposable O2 bottle. Does the Williams system have a regulator that indicates flow rate in some way, so it is repeatable ?

This is the one I got, I think its the same thing, you can set the regulator to 0.5, 1,1.2,1.5 liters/min. I have the disposable one too, but this works much better.

x2. I have that one as well.

Sweet so that regulator hooks up to the red disposable oxygen bottle? What else do I need? A 0.5 micron sintered stone and some vinyl tubing ?

That hooks up to a big bottle of o2. Like a welding bottle. It will cost a little more upfront but last you forever.

That product on Amazon isn't the same thing as the William's O2 system for use with disposable welding oxygen tanks. That product is for refillable O2 tanks. I have the product that the original poster is asking about and I think that what really makes it a great product is the stainless wand/O2 stone that is included with the system. The included regulator is generic; a piece you'll get with any oxygen aeration system made for use with disposable tanks these days.

I suggest the Williams system for the aeration wand. I have no experience with other O2 systems, and these opinions are my own.

edit: I never answered your question. No, the Williams system does NOT include some indicator. I simply do a "one-one-thousand, two-one-thousand... thirty-one-thousand" before shutting it off. I have never had an issue with it.

I'm not interested in investing in a welding oxygen bottle at this point, assuming it costs about as much as a CO2 bottle. I have noted that the hydro test is usually expired by the time I take it in for a refill. How many 5 gallon batches can I aerate with a disposable bottle?

Above is a picture of the regulator. It's just a black knob with no indication of any kind. I just open it until the air stone at the bottom barely causes bubbles to surface. Then I stir slowly for 30 seconds and turn it off.

I did ~15 batches with my first bottle. I'm on my second now.

I have the Williams Brewing Oxygen system. The valve is a little tricky to use, and is a little difficult to get the right flow. But with some practice it is workable. I just open it up until I barely see bubbles coming from the stone with it near the surface and then move it to the bottom of the fermenter and stir slowly for about 30 seconds. Works well for me.

I've used the Williams regulator kit a few times now. It's pretty dead simple to operate. Just open the valve until the Oxygen starts coming out of the stone, and swirl around the bottom of the fermentor for whatever time you deed appropriate (30 seconds to a 1 minute).

I'm not sure a gauge is necessary for this function. If one were to want to know "PRECISELY" how much O2 they were inputting, like for lab experiments, then it might be useful As it is, it's going to be pretty hard to put too much oxygen in your wort.

I don't know how many batches the tanks are worth. I've used mine probably like 4 times now and I'm on the first tank.

I did 40-50 five gallon batches with my first tank.

You can get a lot of mileage out of those little bottles. The first few, however, will probably go faster because (if you're like me) you will probably err on the side of too much O2.
