LP regulator at altitude
Does a LP regulator maintain a constant 11"+/- WC pressure as altitude increases? It would seem that as atmospheric pressure decreases that less force would be exerted on the diaphragm thereby changi...

Doug, I didn't say it wasn't! This is what YOU wrote on the first page... "The output pressure of a LP DOT or ASME will be about 240 psi that the LP regulator drops down to 11.5(or .5 psi) inches water colume". 13.8 isn't even ABOUT the same as 11.5. Craig
Yes, I was off a fraction. I rounded up. But, this is what YOU stated which is COMPLETELY WRONG.
"1 psi = 2.307' of water column = 27.68" wc so 11.5" wc is NOT .5 psi. Craig"
You will notice I clarified the .5 down to about .45. 13.8 is not an outrageous difference in W/C pressure. I was just keeping it simple. YOU, were completely wrong. Doug
