ISO 748:2007 Preview
Hydrometry -- Measurement of liquid flow in open channels using current-meters or floats
This standard was last reviewed and confirmed in 2013. Therefore this version remains current.
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.
