液化天然气加气机计量检定方法的研究

摘要

针对液化天然气(liquefied natural gas,LNG)加气机日益广泛的应用,首先介绍了LNG加气机的组成及工作原理,然后以我国LNG加气机计量检定现状为切入点,提出了LNG加气机的计量检定新方法,即采用LNG加气机检定装置,利用标准表法原理进行LNG加气机计量检定.检定装置的现场运行情况表明:其技术先进、性能稳定,保证了LNG加气机计量检定的准确度.%LNG dispensers are increasingly used day by day. Its composition and working principle are introduced, firstly. Starting from the point of verification status in China, the authors propose a new verification method for LNG dispensers, I.e., the verification device for LNG dispensers isused to verify LNG dispensers according to the master meter method. The results of field operationindicate the precision and reliability of the verification device can satisfy the measurerequirements.
