Application of ADCP Fixed Point Multiple Vertical Line Method in Flow Measurement
ADCP fixed point multi-vertical method adopts the principle of acoustic Doppler frequency shift,which can be used for fixed point vertical velocity measurement and cross section flow measurement.Its application solves the difficult problem of measuring the complicated flow pattern such as large water depth and small velocity in wide shallow river bed.It has the advantages of simple velocity measurement,intuitive output data and abundant result charts.Taking the flow measurement of Majiatan Hydrology Station as an example,the working principle,flow calculation method,successful application example and operation precautions of ADCP fixed point multiple vertical line method are emphatically discussed.The practice proves that compared with the traditional rotor current meter method,the method has higher degree of automation and intelligence,improves the working efficiency,timeliness and safety of the base,has reliable test accuracy and reduces the labor intensity.This method has shown a good prospect of popularization and application in the hydrological flow measurement work,and has played an important role.
