| 摘 要： | 文章分析了在计量液化气储罐内的存量时库存和实际不相符的原因，指出玻璃板式液位计由于环境温度变化，使液化石油气储罐和液位计导管温度存在差异，势必会产生液位偏差。同时提出了解决问题的办法。

| Abstract: | The article analyzes the cause of unequal LPG tank storage between computation and fact and indicates glass board type level meter and LPG tank have difference in temperature due to environment temperature changed. That＇s the reason which causes the storage error. Meanwhile the paper puts forward countermeasure. |
