FIELD: measuring technique.
SUBSTANCE: method comprises measuring flow rate in each section to be calibrated according to the charging curve of the meters, directing water flows that are passed trough the meters to the standard meters mounted at the outlets of the sections, and calculating the mean relative error of the meters throughout the flow rate range by comparing the volume indicated by the meter to be calibrated with the volume indicated by the standard meter.
EFFECT: enhanced efficiency and reduced cost.
