热能表检定装置不确定度评定方法研究

Evaluation Method Research of Uncertainty of Heat Meter Verification Device

热能表检定装置由热水流量检定系统、温度检定系统、计算器检定系统组成。由这些系统组合使用,可完成对热能表的分量检定、分量组合检定或总量检定。从热能表检定装置的整体性能来看,最直接的指标就是装置的测量不确定度,论文对各项影响测量不确定度的因素进行了分析,为热能表检定装置的检定提供了必要的检定依据,也为热能表检定装置的研究打下了坚实的基础。

The thermal meter verification device is composed of the hot water flow verification system, the temperature verification system and the calculator verification system. These systems can be used to verify the components of the thermal energy meter, the component combination verification, or the total amount verification. From the overall performance of the thermal meter verification device, the most direct indicator is the measurement uncertainty of the device. The factors of uncertainty in the measurement are analyzed. It provides the necessary verification basis for the verification of the thermal energy meter verification device. It also lays a solid foundation for the research of the thermal energy meter verification device.
