EFFECTS OF ABNORMAL CONDITIONS ON ACCURACY OF ORIFICE MEASUREMENT

摘要

Whenever one focuses on gas or fluid measurement,he or she will eventually discover an abnormal condition at a measurement station.Invariably someone will ask,"What effect will it have on measurement?" A student of measurement may spend years answering this question.This and similar questions have generated many research studies.This research has enabled us to better understand measurement abnormalities and to improve measurement procedures and standards.Even though we have made great strides in measurement,we will continue to ask this question.
