标准范围

ISO 5167-1:2003定义了术语和符号，并确立了通过压差装置（孔板、喷嘴和文丘里管）测量和计算管道中流体流量的方法的一般原则，这些压差装置被插入满管的圆形横截面管道中。ISO 5167-1:2003还规定了测量方法、安装和流量测量不确定度测定的一般要求。它还定义了使用这些压差装置的管道尺寸和雷诺数的一般规定限制。ISO 5167（所有部分）仅适用于在整个测量段内保持亚音速且流体可视为单相的流动。它不适用于脉动流量的测量。

ISO 5167-1:2003 defines terms and symbols and establishes the general principles for methods of measurement and computation of the flowrate of fluid flowing in a conduit by means of pressure differential devices (orifice plates, nozzles and Venturi tubes) when they are inserted into a circular cross-section conduit running full.ISO 5167-1:2003 also specifies the general requirements for methods of measurement, installation and determination of the uncertainty of the measurement of flowrate. It also defines the general specified limits of pipe size and Reynolds number for which these pressure differential devices are to be used.ISO 5167 (all parts) is applicable only to flow that remains subsonic throughout the measuring section and where the fluid can be considered as single-phase. It is not applicable to the measurement of pulsating flow.
