非接触缆道雷达波流量测验系统在崇阳(二)水文站的应用

Application of non-contact cableway radar flow measurement system in comparison analysis of flow coefficients at Chongyang(2)Hydrological Station

雷达波流速仪具有测量速度快、可靠性高、安全性强等优势,在水文勘测中得到了广泛应用。为了更好地控制崇阳(二)水文站洪水流量变化过程,并解决其在洪水抢测中存在的问题,通过对传统流量测验与雷达波流量测验的对比分析,对其在流量测验中的改正系数进行了率定。流量比测结果表明:系统误差不符合相关规范要求,建议在未来测验过程中尽量避开水流出现紊流、水位涨落率大以及风速大等情况。

The radar flow meter features as fast,high reliability and high security,and has been widely applied in hydrological survey.To better monitor hydrological station and to resolve emergency measuring problems during the flood,we conducted comparison analysis between traditional flow measurement and radar flow measurement,and calibrated its correction coefficients.The results showed that systematic errors failed to meet the requirements.It is suggested that situations such as turbulent flow,high fluctuation level of water level,and high wind velocity should be avoided during the survey.
