采用ADCP进行流量测验,具有不扰动流场、可连续施测、测流历时短的特点,能够提高所测流量的代表性,降低测验强度,是目前世界上最先进的流量测验设备。本文简单介绍ADCP基本原理,流量的计算方法,通过ADCP测验中流量的形成过程,分析流量测验误差的来源,从优化测验方法与设备测验参数配置等角度,降低测验中产生的误差,最终达到提高ADCP流量测验资料精度的目的。
It is the most advanced flow test equipment in the world by using ADCP to carry out flow test. It has the characteristics of not perturbing the flow field, continuous measuring and short measuring flow duration. It can improve the representativeness of measured flow and reduce the test intensity. This article briefly introduces the basic principle of ADCP, flow calculation method, through the ADCP test flow formation process, analysis of the source of flow test error, from the optimization of test methods and equipment test parameters configuration point of view, to reduce the error in the test, and ultimately to improve ADCP flow test data accuracy purposes.
