Online Computers for Custody Transfer

摘要

With the advent of Electronic Flow Measurement came a variety of calculation, auditing and calibration algorithms. Each manufacturer wrote software to meet either a producer's requirement or their own proprietary algorithms. These algorithms, while being effective, were by nature vastly different from one manufacturer to the next. These differences made it necessary to develop a standard for custody transfer meters so that regardless of the manufacturer, the measurement data will be consistent from one meter to the next. This standard became API Chapter 21 -Flow Measurement Using Electronic Metering Systems, Section 1 -Electronic Gas Measurement.
