Most oxygen regulators only regulate pressure but the Blichmann Oxygen Flow Regulator allows you to dial in the actual rate of flow. Turn the dial to your preferred flow rate, measured in liters of oxygen per minute, and you can feel confident in knowing precisely how much oxygen is being introduced into your wort. It is important to know the flow of oxygen because depending on your downstream restriction the actual flow can vary a lot. Remove the guess work with the Oxygen Flow Regulator from Blichmann.
