  • In this paper, an experimental water tank and a tank crane are used to design a calibration test method. By carrying out multiple sets of ocean current measurement experiments, the measurement performance of the electromagnetic ocean current meter is technically analyzed. The results show that the absolute value of the maximum indication error of the flow velocity is 1 cm/s, and the absolute value of the maximum indication error of the flow direction is 2°. The tank flow field calibration technology provides a new and effective way for the ocean current parameter value transfer of electromagnetic current meters.
