标准摘要
[中文适用范围]： 涉及河流和人工渠道的流量测量。 所考虑的流动条件仅限于稳定流动，其唯一依赖于上游水头。 取决于下游和上游水位的淹没水流不包括在内。 取消并取代第一版 (ISO 4374 :1982)，它构成了技术修订版。 [外文原描述]： Deals with the measurement of flow in rivers and artificial channels. The flow conditions considered are limited to steady flows which are uniquely dependent on the upstream head. Drowned flows, which depend on downstream as well as upstream levels, are not covered. Cancels and replaces the first edition (ISO 4374 :1982), of which it constitutes a technical revision.
