Describes the procedure used for the calibration of current meters. It specifies the type of tank and equipment to be used and the method of presenting the results. Does not take into account any possible difference existing between the behaviour of a current meter moving in motionless water and that of a fixed current meter in turbulent flow. Includes definitions, principle of calibration stations, dimensions of calibration tank, rating carriage and measuring equipment.
