Unaccounted-for Gas Project. Measurement Task Force (Orifice Meter Studies). Volume 2B

摘要

The study was aimed at determining unaccounted-for (UAF) gas volumes resulting from operating Pacific Gas and Electric Co.'s transmission and distribution systems during 1987. Activities and methods are described and results are presented for research conducted on orifice meter accuracy. The Measurement Task Force determined that orifice metering inaccuracies were the largest single contributor to 1987 UAF.
