Through comparative analysis of H-ADCP measurement data and manually measured flow data in Wangting (Interchange) hydrological station, combining with the characteristics of H-ADCP, the index velocity method is used to calibrate the relation of cross-section velocities which are measured by H-ADCP and cableway current meter method. The steady line precision meets the specification requirements. On this basis, the measured data are compared for error statistics and velocity formula is given. The online measuring data meet the practical requirements.
