液化天然气加气机检定装置研制

Research of LNG dispensers verification device

介绍了LNG加气机的组成、工作原理以及中国LNG加气机计量检定现状。针对LNG加气机校准中采用的质量法的不足,研制了标准表法原理的LNG加气机检定装置,该装置的试验情况表明,其性能稳定、计量准确、操作方便。

The composition,working principle and verification status of LNG dispensers in China were introduced.According to the defect of mass method in calibration of LNG dispensers,the LNG dispensers verification device was developed,which applying the master meter method to verify LNG dispensers.Experiment of the device was performed and results indicate that the device had steady performance,high efficiency and flexible configuration.
