摘　　要：H-ADCP测流系统是一种先进的流量测量设备,它利用声学多普勒效应和剖面技术相结合,实现对流体流速的高精度、实时监测,应用领域广泛。其技术应用的关键是指标流速与断面平均流速关系的率定。以祯埠水文站的应用情况为例,论述指标流速与断面平均流速关系率定的实质与内容,以H-ADCP监测指标流速,以常规转子流速仪测定断面平均流速(或走航式ADCP测定断面平均流速),在收集一定资料成果后,率定出最佳相关方程,可为祯埠水文站及类似水文站开展H-ADCP在线流量监测资料整编等提供经验和技术依据。The H-ADCP flow measurement system is an advanced flow measurement equipment that uses the acoustic Doppler effect and profile technology to achieve high-precision,real-time monitoring of fluid flow velocity and has a wide range of applications.The key to its technical application is the calibration of the relationship between the index flow velocity and the cross-section average flow velocity.Taking the application of Zhenbu Hydrological Station as an example,the essence and content of the relationship between the index flow rate and the average cross-section flow rate are discussed.H-ADCP is used to monitor the index flow rate,and the conventional rotor current meter is used to measure the cross-section average flow rate(or the navigation ADCP measurement).Section average flow velocity),after collecting certain data results,the best correlation equation is calculated,which can provide experience and technical basis for Zhenbu Hydrological Station and similar hydrological stations to compile H-ADCP online flow monitoring data.
