摘要
通过介绍SVR-VP电波流速仪的工作原理和主要技术指标,以及下拉秀站电波流速仪水面系数的比测试验分析,总结分析该仪器在青海三江源区水文监测工作应用中积累的一些经验。分析结果表明,电波流速仪性能比较稳定,在一定条件下能够替代浮标完成流量测验,测验质量满足水文规范要求。该仪器可作为水文巡测的常规流量测验仪器,可供今后在高海拔地区使用电波流速仪参考。
We introduced the working principle and main technical parameters for SVR-VP electric wave current-meter,and measured and compared the surface flow-velocity coefficient at Xialaxiu Hydrological Station using electric wave current-meter.Some experiences are gained from hydrological monitoring of the Three-river Source Region in Qinghai Province using electric wave current-meter.The results show that performance of electric wave current-meter is relatively stable and it can replace buoy for discharge measurement in certain conditions,and its measurement quality meets requirements of hydrological norms.Therefore,SVR-VP electric wave current-meter can be used as routine discharge measurement instrument for tour hydrometric gauging,which provides some reference for instrument using in high altitude area.
