标准摘要
[中文适用范围]： 本文件规定了确定在明渠中流动的水的速度和横截面积以及使用点速度测量装置计算流量的方法。 它适用于使用旋转元件海流计、声学多普勒测速仪（ADV）、声学多普勒电流剖面仪（ADCP）固定方法、表面速度测量（包括浮子和其他表面速度系统）的方法。 尽管讨论了一些通用过程，但本文档没有详细描述如何使用或部署这些系统。 注：有关详细程序，请参阅仪器制造商和相应公共机构的指南。 [外文原描述]： This document specifies methods for determining the velocity and cross-sectional area of water flowing in open channels and for calculating the discharge employing point velocity measurement devices. It is applicable to methods using rotating-element current meters, acoustic doppler velocimeters (ADVs), acoustic doppler current profiler (ADCP) stationary method, surface velocity measurement including floats and other surface velocity systems. Although some general procedures are discussed, this document does not describe in detail how to use or deploy these systems. NOTE For detailed procedures, refer to guidelines from instrument manufacturers and the appropriate public agencies.
