标准摘要
[中文适用范围]: 本文件提供了选择特定类型的流量测量结构来测量明渠中的液体流量的指南。 它以简单的非技术术语描述了各个结构的功能,并列出了需要考虑的因素和参数,以便就使用哪种类型的结构做出明智的决定。 本文件给出了描述使用这些结构所涉及的限制和不确定性的相关参数值。 表 1 中列出的各个标准给出了特定类型结构的更多明确细节,这些标准涵盖了每种类型的结构。 [外文原描述]: This document gives guidelines for selecting a particular type of flow measuring structure for measuring liquid flow in an open channel. It describes how the individual structures function in simple non-technical terms, and sets out the factors and parameters to take into account in order to make an informed decision on which type of structure to use. Values of the relevant parameters describing the limitations and uncertainty involved in the use of these structures are given in this document. More definitive details of a particular type of structure are given in the individual standards listed in Table 1, which cover each type of structure.
