Abstract:In order to solve the problems of nonstandard use of some professional terms, inconsistent translation and different classification in the practical application of current meters, referringto the national standards, industry specifications and relevant literature, combined with the principle and application of current measurement, this paper figured out the naming, classification,scope of application, characteristics and development direction of various types of current meterssystematically, which could also promote the development and application of ocean observationinstruments. The results showed that the current meter could be defined as “an instrument formeasuring the velocity and direction of sea water".The current meters were mainly divided into4 categories: mechanical current meters, electromagnetic current meters, acoustic current metersand other current meters according to the working principle and different types of current metershad their own characteristics. Mechanical current meters mainly included Ekman current meter,printing current meter, photographic current meter, magnetic recording current meter, telemetering current meter and direct reading current meter. Electromagnetic current meters mainly included geomagnetic electromagnetic current meter and artificial magnetic electromagnetic currentmeter. Acoustic current meters mainly included acoustic doppler current profiler, acousticdoppler current single point current measuring instrument, acoustic doppler current meter andtime different acoustic current meter. Other current meters mainly included laser doppler anemometry, resistance current meter, strain current meter, inclined current meter, particle imagevelocimeter and ocean turbulence profiler.

海流是海洋动力环境的重要参数 ,对全球气候稳定、海洋生态系统平衡和海洋开发利用等发挥至关重要的作用 , 因此海流观测技术一直是海洋观测领域的关注焦点之一[1-2]。
为在恶劣的海洋环境下准确和便利地观测海流 ,人类自17世纪开始使用漂流瓶和海冰等漂浮物观测表层海流 , 开启人类观测海流的历史[3]。……
