通过分析流量计油量计算方法、两国三站密度水分比对、阿拉山口离线实验室内密度测定质量控制、阿拉山口计量站在线与实验室离线密度比对,并对不同水分检验标准比对及试验验证,最终确定中哈两国净重输差主要来源于两国水分检验标准的差异,为企业挽回巨大的经济损失。 By analyzing the method of flowmeter oil quantity, density ratio of three stations in two countries, the quality control of Alashankou off-line laboratory density measurement, the online density of Alashankou metering station and the laboratory off-line density, and comparison of different moisture test standards And test verification, and ultimately determine the net output difference between China and Kazakhstan net mainly from the differences between the two countries water testing standards for enterprises to save huge economic losses.
