浅析ADCP测流技术及使用中应注意的问题

Analyses of ADCP Technology in Flow Measurement and Problems

传统测流方法手段落后、信息化水平低,不能很好地适应新时期水文测报快速、准确、精度高、任务多的要求。ADCP测流仪器的引进较好地解决了这一问题。作为新的测流仪器具有精度高、速度快、信息化水平高等突出优势。ADCP测流方式、使用方法、适应条件与传统仪器有很大区别,本文通过分析ADCP测流原理、使用过程中容易出现的问题,提出了ADCP测流中需要注意的各种事项,从而促进ADCP流量测验工作发展。

the traditional flow measuring methods is lagging behind and the level of information is low, it can＇t meet the requirements of hydrological telemetry in new period. As a new flow measured instrument with outstanding advantages of high precision, high speed and higher information level, the ADCP technology can solve this problem. There is very differ- ent in flow measured mode, using method and adaptive conditions between the ADCP technology and the traditional flow measuring methods. This paper analyzes the flow measured theory of ADCP technology and problems are easy to appear in using process, the points for attention are proposed in the ADCP flow measurement, and it will be promoted the development of ADCP flow test work.
