摘　　要：采用实验水槽和水槽天车,设计校准试验方法,开展多组海流测量试验,对电磁海流计计量性能进行技术分析。结果显示,流速最大示值误差绝对值是1 cm/s,流向最大示值误差绝对值为2°。实验水槽流场校准技术为电磁海流计海流参数量值传递提供了一种新的有效途径。In this paper,an experimental water tank and a tank crane are uscd 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 drection is 2°.The tank flow field calibration technology provides a new and ffective way for the occan current parameter value transfer of electromagnetic current meters.
