Gas Flow Measurement
Gas Flow Measurement
(OP)
Is it always necessary to have temperature and pressure compensation when measuring fuel gas flow? I can understand it for custody transfer and for any down hole injection or gas extraction from a well. But if it is for something basic like instrument fuel gas supply I am not sure.
Any thoughts or knowledge on this?
Thank you.

RE: Gas Flow Measurement
If it is reported to a state or federal agency, sooner or later you will be audited and get hit with a fairly arbitrary fine. If you have to pay royalties on lease use, check your contract, some allow you to estimate (and most of those do not specify an estimation method) and you can get by without knowing current temperature (but you do always have to know pressure).
If you are using a differential producer then you can't do measurement without a pressure input. If you are using another technology, you'd be better off just making the numbers up. Really. The density and momentum of 15-30 psig natural gas is just too low for any other technology to provide meaningful numbers.
