Measurement of liquid flow in open channels - Velocity-area methods
出版：International Organization for Standardization
专家解读视频
This International Standard 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.It covers methods of employing current-meters and floats to measure the velocities. Although, in most cases, these measurements are intended to determine the stage-discharge relation of a gauging station, this International Standard deals only with single measurements of the discharge; the continuous recording of discharges over a period of time is covered in IS0 1100-I and IS0 1100-2.NOTE The methods for determining the velocity and cross-sectional area of water flowing in open channels with ice cover are specified in IS0 9196.
