When a venturi flow meter is placed in a pipe carrying the fluid whose flow rate is to be measured, a pressure drop occurs between the entrance and throat of the venturi meter. Happily this burner has solved my problem. The regulators are controlled by knobs that allow you to determine how much gas is allowed through the valve to the burner. Try it yourself. Propane Outdoor Fish Cooker Smoker Burner 5 1 2 Round with Orifice | eBay But if you really want a single flame burner, all the info is on the Ron Reil page I linked to above- how to make the venturi, what size to drill the tip- its all there. The larger on is a 33 hole and the smaller burner has 11 holes. It is common that these lips will corrode which inhibits the venturi from locking securely into place. He says that the gas comes shooting out of the orifice like a jetstream, going right past the air opening and into in the venturi tube. As the volume of fluid is forced through the reduced diameter fluid dynamic laws determine that the increased flow velocity be accompanied by a pressure drop.
