摘要: 研究了液化石油气(LPG)气相对罐内液相计量的影响, 对LPG计量中产生的差值进行了分析和计算, 提出了以系数修正法和加装高精度计量设备来减少LPG计量误差的方法。Abstract: The problem on metering error of LPG measured under gas phase state is studied.The study result shows that the metering accuracy of LPG measured under liquid phase state is influenced by gas phase's LPG, which produces a remarkable metering error.To solve this problem, the author presents the factor correction method and a method to install high precision metering device to reduce metering error of LPG.
