Why flow rate is helpful
Most regulators that homebrewers use for oxygenating wort are simple setups – Example – via William’s Brewing. They attach to disposable oxygen tanks (typically sourced from a local hardware store) and are little more than on and off valves. No gauges, no pressure control (other than the degree to which you open and close the valve) and no flow control.
Time and rate give you an idea of how much oxygen you’re really adding to your wort. Time is easy to track. Rate, not so much, at least with typical homebrew O2 regulators. If you want more or less oxygen for your next batch, it’s mostly a guessing game.
Being able to set or monitor flow rate allows along with keeping track of time allow you to better control oxygenation.
Notes from HBF: This regulator is designed for CGA-870 oxygen tanks. It includes both a regulator also allows you to set flow rate.
