Application of single beam acoustic Doppler current meter in vertical online flow measurement

通过应用单波束垂向式声学多普勒流速仪(V-ADCP)进行在线流量测验,探索单波速V-ADCP的安装和流速数据处理计算方法。采用转子式流速仪对V-ADCP进行比测,分析V-ADCP采用相对水深某个区间范围内的单元流速计算垂线平均流速的方法,率定符合水文相关规范的V-ADCP测流的单断速关系,并确定单断速关系可生产应用的范围。通过对V-ADCP在线测流的应用,得到精度较高的单断关系,实现流量在线监测,可为进一步推广V-ADCP在线测流的应用进行探索。

The installation of single wave velocity V-ADCP and the calculation method of velocity data processing are explored by using a single beam vertical acoustic Doppler velocimeter(V-ADCP)for on-line flow measurement.The V-ADCP is comparatively measured by rotator velocimeter.This paper analyzes the method of calculating the average vertical velocity by unit velocity in a certain range of relative water depth,calibrating the single-break velocity relationship of V-ADCP according to relevant hydrological norms,and determining the scope of production and application of the single-break velocity relationship.Through the application of V-ADCP on-line flow measurement,it obtains the single-break relationship with high accuracy,and the automatic flow monitoring is realized.The preliminary exploration is made to further popularize the application of V-ADCP on-line flow measurement.
