为提高测流统计成果的精度,同时为避免由于水流测次问题而导致的资料整编当中产生径流量的相关误差,文章采用对比分析的方法,采用既能减少单次测流工作量、减少测流时间、减少测流速误差,也符合相关规定的流速仪流速测验方法。采用这种方法对流速测验的次数予以增加,能够将日流速变化进行准确掌握,进而提高连实测流速过程线法对流量资料整编的精度,同时也能够提高测流统计的结果精度。
In order to improve the precision of the statistic results of the flow measurement and to avoid the relative error of the runoff caused by the data reconciliation of the flow measurement, the article adopts the method of comparative analysis, which can reduce the workload of a single flow measurement, Flow time, reduce the error of the measured flow rate, also in line with the relevant provisions of the flow meter flow test method. In this way, the number of flow test is increased, the daily flow rate variation can be accurately grasped, and then the accuracy of flow data reassembly with the actual measured flow process line method can be improved. At the same time, the accuracy of flow measurement statistics can also be improved.
