明渠水流测量 用有限垂线数测验的速度面积法

Liquid flow measurement in open channels; velocity-area method using a restricted number of verticals

ISO/TR 9823-1990 发布历史

This Technical Report describes a velocity-area method which can be carried out using three verti-cals only, without significant loss of accuracy, and gives advice on when such a "short-cut" method should be used. The method specified in this Technical Report is not an alternative to the velocity-area method specified in ISO 748, which gives accurate results and should be used under normal conditions. This short-cut method has a limited field of application and is in-tended for use only in special circumstances, ex-amples of which are given in clause 7.

ISO/TR 9823-1990由国际标准化组织 IX-ISO 发布于 1990-09，并于 1990-09-01 实施。

ISO/TR 9823-1990 在中国标准分类中归属于: B05 农林技术，在国际标准分类中归属于: 17.120.20 明渠中流量的测量。
