Abstract
The quality of elbow flowmeter is important to its application accuracy. This paper described the digital quality evaluating method for elbow flowmeter which based on the analysis of elbow flowmeter’s theory, construction, working condition, and fault characteristics. In the method, we applied the concept of static quality, dynamic quality and used quality index to show the quality condition of flowmeter precisely. The fuzzy math theory, finite element analysis technology and online detection technology were used in our method. The digital quality evaluation system can get more accurate testing values, more stable dynamic performance and faster fault diagnosing for flowmeter .
