propane meter

Unread postAuthor: Grignacke » Thu Sep 02, 2010 9:00 pm

Hello. Is it possible to create a propane meter...
1) ball valve
2) length of pipe with the pressure gauge here
3) ball valve
without a regulator?
Also, would the real gas law be used to find the volume of the length of pipe based on pressure?
Thanks in advance :D

Yes. You need to figure out how much pressure to put in the pipe before releasing it into the chamber. Thats how i made all of mine, I've never used a regulator. Just a torch head with a hose clamped on, a set of ball valves and a piece of pipe between them with a pressure gauge on it.
