摘　　要：油耗仪是通过单位时间燃油消耗量实现对机动车油耗的测定。燃油消耗量可用体积或者质量表示。质量法油耗仪正是利用称重传感器测定单位时间消耗的燃油质量实现对油耗仪的校准,因此计算其示值误差不确定度有重要意义。The fuel consumption meter measures the fuel consumption of a motor vehicle by the fuel consumption per unit time.Fuel consumption can be expressed in terms of volume or mass.The mass method fuel consumption meter uses the load cell to measure the fuel quality per unit time to achieve the calibration of the fuel consumption meter.Therefore,it is important to calculate the uncertainty of the indication error.
