Liquid flow measurement in open channels — Velocity-area methods — Collection and processing of data for determination of errors in measurement

For determining the discharge in open channels by the velocity-area method, components of the flow need to be measured. The total uncertainty in discharge is a combination of the uncertainties in these components. This ISO-Standard specifies a standard basis for collecting and processing the data required to compute the component uncertainties for determining the total uncertainty in discharge.
