摘要
应用电波流速仪测量水面流速，通过水面流速系数的计算，可以得到某河流的流量。通过LD15—1型电波流速仪的实测应用，证实了这种仪器在实践中性能稳定，精度可以满足目前相关的技术规范要求。电波流速仪测流时间短，速度快，质量可靠，因此完全可以用来代替均匀浮标。通过对“04．8”洪水中电波流速仪得到的资料分析，应用0．9为水面流速系数是合理的。
The electric flow meter can be used to measure the surface watervelocity and then the discharge ot river can be get by calculating the water surface velocity coefficient. According to the application of LD15-1 electric flow meter, it was validated that this equipment has a stable performance in practice and the accuracy of measurement can satisfy the current related technical specifications. The advantages are timesaving, sensitive and reliable, so that it can succeed the uniform buoyage. According to the analysis to the data gained by electric flow meter during flood ＂04.8＂, using 0. 9 as the water surface velocity coefficient is reasonable.
