标准范围

ISO 748:2007规定了在无冰盖的明渠中测定水流速度和横截面积以及计算流量的方法。ISO 748:2007涵盖了使用流速计或浮子测量速度的方法。它只处理放电的单一测量；ISO 1100-1和ISO 1100-2涵盖了一段时间内放电的连续记录。

ISO 748:2007 specifies methods for determining the velocity and cross？sectional area of water flowing in open channels without ice cover, and for computing the discharge therefrom.ISO 748:2007 covers methods of employing current？meters or floats to measure the velocities. It deals only with single measurements of the discharge; the continuous recording of discharges over a period of time is covered in ISO 1100-1 and ISO 1100-2.
