PRACTICAL CONTROL OF DYNAMIC METERING SYSTEM AND DATA ACQUISITION

摘要

Measurement is the basis of scientific and industrial research. It allows us to understand the phenomena we observe in our environment by means of experimental deduction and verification. One of the most difficult problems facing the instrument engineer is the accurate calibration of dynamic metering system of fluid (liquid or gas). The purpose of this paper is to review the essential definitions, roles and characteristics of metering system of fluid. We discuss measurement and metrological control of a signal sensor from dynamic metering systems. After that, we present descriptive way of calibration instruments with more detailed discussions to the reference standards for method of test This paper describes experimental evaluation of the error on metering system. Also included are procedures using for validation test, after compared this error with the maximum errors tolerated defined by specifications and standards.
