Propane meter question.
Posted: Fri Feb 18, 2011 9:48 am
So I think I have down the concept of the propane metered spud gun. I understand that the optimal combustion environment for propane is 4% gas to oxygen volume in the comb. chamber. My question is this. When doing the math to figure out how much propane you need to meter for your specific set up (comb. chamber size, etc.) what is most important? From what I've read it appears as if the propane meter size (pipe diameter and length) doesn't matter as long as you know you're filling it with 4% of your combustion chamber volume. How can you regulate this? Do you need to adjust the setting on your pressure regulator / PSI indicator, or do you need to adjust the size of your meter pipe?
I've seen guys online selling propane meters that claim to work with any combustion chamber. This is confusing to me since they have no idea what size / volume your combustion chamber actually is, therefore do not know 4% of it. This leads me to believe that the meter pipe dimensions are insignificant and that the pressure regulator / PSI indicator does all of the "work" here. Or is both size and pressure essential factors in the equation?
Thanks guys, I'm new here, so I hope I'm not repeating a question that's been asked a thousand times!
Best,
Tom
