A REVIEW OF THE REVISIONS TO API 14.3/AGA 3 PART 2

摘要

In order to produce accurate measurement using an orifice metering system, flow conditioning must be adequate to reduce swirl angles and non-uniform flow profiles to acceptable levels. In addition, the internal condition of the system must meet standard requirements and be relatively free of rust, scale, pitting, hydrates, ice, gaps, protrusions, and contaminants in the run or on the orifice plate itself. Compliance with the latest revision of API Chapter 14.3 will insure very good measurement performance which meets custody transfer recommendations.
