摘要:

阐述了标准表法液化石油气(LPG)加气机检定装置的检定原理、结构组成、技术特点,并对其测量结果的不确定度进行了分析与评定。结果 表明该检定装置完全满足JJG 997—2005的有关要求。LPG加气机检定装置的研制成功,不仅为LPG公平公正的贸易结算提供了有力的检测手段,而且为各级计量技术机构对LPG加气机的计量检定、质量监督、技术评价和法制管理提供了高质量、高水准的技术装备。

Abstract:

This paper introduces the verification principle,structure composition and the technical characteristics of liquified petroleum gas(LPG) dispensers verification device based on standard meter method,analyzes and evaluates its uncertainty of measurement results.The results show that the device can completely meet specified requirements of JJG 997-2005.The LPG dispenser verification device can not only be a powerful detection means for fair trade settlement of LPG,but also be a high quality and high level for metrological verification,quality supervision,technology assessment and legal management of LPG dispensers.
