国产H-ADCP替代进口H-ADCP在水文流量测验的应用探究OA

This article takes the flow measurement test at the Xinshao Hydrological Station as a starting point,deeply analyzing the technical performance and application effects of the domestic SLA150-1 type H-ADCP and the imported Son Tek SL500-C type H-ADCP in hydrological flow measurement.By comparing technical parameters,measurement accuracy,stability,and adaptability,combined with the actual measurement data from the Xinshao Hydrological Station and multidimensional analysis,it demonstrates the significant advantages of domestic equipment in measurement range,profile coverage capability,and low flow scenarios.The research results indicate that the domestic SLA150-1 performs excellently in high flow measurement during flood periods and full cross-section coverage,with a relative error of 6.96％in low flow scenarios,which is significantly lower than that of imported equipment(12.2％).To address issues such as insufficient low flow accuracy and lack of long-term stability verification for domestic equipment,suggestions such as optimizing algorithms and improving standard systems are proposed,providing theoretical and practical support for the promotion and application of domestic H-ADCPs.
