标准砝码法在校准质量式油耗仪中的应用

Standard weights method in the application of fuel consumption meter calibration quality type

为了对标准砝码法校准质量式油耗仪进行定量评价,来验证标准砝码法校准质量式油耗仪是否具有可行性,本文通过对标准砝码法校准质量式油耗仪的测量原理及数学模型进行解读,确定了标准砝码法校准质量式油耗仪测试结果的不确定度的来源,对该方法的测试结果的不确定度分量进行分析与计算,并对该方法的各不确定分量度进行合成,得到的扩展不确定度为0.28%。研究结果表明:用标准砝码法校准质量式油耗仪的检测结果离散性小,测试质量好,用该方法校准质量式油耗仪具有可行性。

In order to make a quantitative evaluation of the standard weight method to proved that the standard weight method is feasible to calibration mass fuel consumption meter, the working principle and mathematical model of calibration mass fuel con- sumption meter by farmar substitution weighing method are analyzed in this paper. The sources of the uncertainty are determined and analyzed,finally the expanded uncertainty 0. 28% is obtained. The results show that the discreteness are small and measure quality is excellent which proved calibrating mass fuel consumption meter by farmar substitution wei~,hinz method is available.
