EFFECTS OF ABNORMAL CONDITIONS ON ACCURACY OF ORIFICE MEASUREMENT Class # 1100

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.It is this question that has led to the development of this paper.Instead of focusing on certain specific abnormalities,this paper addresses the overall subject of measurement abnormalities and presents some investigative tools for the readers as they attempt to answer this question.However,before we can understand measurement abnormalities,it is important to review proper or accurate measurement.
