Take the guesswork out of oxygenation with this handy flow meter. If you're using pure O2 to oxygenate your wort, you're likely using a disposable cylinder with a simple brass regulator, and have no way to measure how much oxygen is actually being added. You're essentially left to finding the "sweet spot" on the dial when you open the regulator and aim for the same spot on the next use. Get repeatable results by adding this flow meter to your setup. This device will allow you to dial in the flow rate and help you add the same amount of oxygen from batch to batch.

The flow meter comes with male flare thread inlet and outlet and includes two Duotight fittings. It's ready for use with 8 mm OD EVABarrier tubing right out of the box, or you can add a swivel nut and barb for use with other size tubings.

Once yeast pitching temperatures are reached, we recommend using a 0.5 micron diffusion stone and adding pure O2 at a 1L/minute flow rate for 60 seconds to acheive the recommened 10-14 ppm dissolved oxygen.

Easy Setup and Operation at a Reasonable Price
I never knew how much oxygen I had put into my wort or starters - probably too much. This unit is easy to set up, easy to use, and introduces an accurate amount of oxygen - all at a reasonable price.
