标准范围

ISO/TR 9824:2007提供了流量测量方法的概要，这些方法可以部署在封闭管道中，部分流动，即具有自由开放的水面。本技术报告提供了每种方法的简要说明，并在适当情况下特别参考了其他国际标准、每种技术的属性和局限性、流量测定中可能存在的不确定性水平以及具体的设备要求。本文引用的不确定性为扩展不确定性，覆盖系数为2，近似置信水平为95%。

ISO/TR 9824:2007 provides a synopsis of the methods of flow gauging that can be deployed in closed conduits flowing part full, i.e. with a free open water surface. This Technical Report provides a brief description of each method with particular reference to other International Standards where appropriate, the attributes and limitations of each technique, possible levels of uncertainty in the flow determinations and specific equipment requirements. The uncertainties quoted herein are expanded uncertainties with a coverage factor of 2 and an approximate confidence level of 95 %.
