声学多普勒测流仪原理及应用

多普勒流速仪（ADCP）利用声学多普勒原理测量水流剖面的流速,是一种新型高精度流体测流仪器.多普勒测流与传统测流方法相比,具有测验分辨率高、精确度好、信息量大、资料完整等优点,尤其适用于复杂环境下的流体流速、流量的测量.文章透过多普勒测流与传统测流的对比,详细地阐述了多普勒测流的原理及方法.

Principle and application of acoustic Doppler current profilers

Acoustic Doppler current profi instrument, measures the flow rate of Doppler. Compared with the traditional accuracy, large amount of data and data velocity and flow rate under the comp lers（ADCP）, a new type of high-precision fluid measurement the flow velocity profile by using the principle of acoustic method, it has many advantages with high test resolution, integrity. It is especially suitable for the measurement of fluid licated environment. This paper describes the principle and method of acoustic Doppler current profilers in detail.
