加油机检定过程中温度测量的改进

Improvement of Temperature Measurement in the Process of Oil Tanker Verification

加油机在周期检定中,偶尔会遇到刚经过检定合格的加油机隔了几个星期再去抽检却不合格,特别是检定时加油机的示值误差处在(±0. 2~±0. 25)%之间,这种情况更为严重。经过试验和现场检测分析,我们发现这与加油机检定过程中温度测量的正确性密不可分。故本文针对加油机检测过程中温度计的选型和使用做了一些实验和分析,以作参考借鉴。

In the periodic verification of the refueling machine,occasionally,the qualified refueling machine will be checked only a few weeks later,but it is not qualified.Especially,the indication error of the refueling machine is in the range of(0.2~0.25)%,this is even more serious.Through the test and field test analysis,we found that this is closely related to the accuracy of temperature measurement in the process of Fuel Dispenser Verification.Therefore,this paper makes some experiments and analyses on the type selection and use of the thermometer in the process of testing the tanker for reference.
