[foxboro] Natural Gas Temp & Pressure compensation

Hello all,

I was wondering if someone had the formula in their back pocket for 
taking a DP on a natural gas line and converting it to a compensated flow.

I have a DP orifice plate that is scaled from 0-235 " water.    This, I 
am told corresponds to  0-2000 CFM.
I have a PT scaled from 0-130 PSI
I have a TT scaled from 0-300 deg F.

So a DP of 100" H2O at 80 Deg F and 100 PSI is ??????SCFM.

So can one of you Chemical Engineers lend a hand?

Thanks,
David
