Performance Evaluation Gas Energy Measurement and Analysis System
In order to meet the demand for natural gas energy measurement,this article analyzes and studies GB/T 28766"Per-formance Evaluation of Natural Gas Analysis Systems",and explores the use of the requirements for A-level measurement system physical parameters in GB/T 18603"Technical requirements of measuring systems for natural gas"as the basis for determining the e-valuation results,and illustrates the evaluation process with examples.After summarizing the evaluation results of the examples,three guiding suggestions are given for conducting performance evaluation of natural gas analysis systems.Firstly,the Monte Carlo uncer-tainty evaluation parameters should choose components.Secondly,the evaluation criteria should be based on the maximum allowable error of compression factor and high heat generation in the A-level measurement system in GB/T 18603.Thirdly,the standard gas used for evaluation should be combined with the actual analysis.
