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 quantitatively evaluate the mass-based fuel consumption meter calibrated by the standard weight method, it is feasible to verify whether the standard mass-weight method calibrates the mass fuel consumption meter. By measuring the calibration principle and mathematical model of the mass- The source of the uncertainty of the test result of the mass-type fuel consumption meter calibrated by the standard weight method is determined, the uncertainty components of the test result of the method are analyzed and calculated, and the uncertainties of the method are synthesized , The expanded uncertainty is 0.28%. The results show that the test results of the mass type fuel consumption meter calibrated by the standard weight method have the advantages of small discreteness and good test quality. It is feasible to calibrate the mass type fuel consumption meter by this method.
