本国际标准规定了一种使用梯形流量计在明渠中进行稳定流量测量的方法 模块化和非模块化条件下的宽顶堰。在这两种情况下都考虑了堰的使用 矩形和梯形通道。 7.6和8.6中给出了堰的使用限制。

This International Standard specifies a method of steady-flow measurement in open channels using a trapezoidal broad-crested weir under modular and non-modular conditions. Consideration is given to the use of the weir in both rectangular and trapezoidal channels. Limitations to the use of the weir are given in 7.6 and 8.6.
