水利部水文司于1992年3月26——28日在南京主持召开了“流速仪检定系数稳定性研究成果”评审讨论会。参加会议的有13个单位25名代表。会上,首先由南京水利水文自动化研究所高级工程师杨汉塘详细介绍了有关流速仪检定系数的稳定性等研究成果,并介绍了流速仪内摩阻力距仪等检测仪器。与会代表对该课题研究成果进行认真评议后认为: 1.该课题研究经过长达十年之久的探讨,并通过12000多架次大量水槽检定资料的统计、分析、论证提供的大量资料,为将来大量减少流速仪送水槽
Hydrology Department of the Ministry of Water Resources in March 26, 1992 -28 days held in Nanjing, “the Velocity Meter Verification Coefficient Stability Research Results” review forum. There were 25 representatives from 13 units participating in the conference. At the meeting, firstly, Yang Hantang, a senior engineer of Nanjing Institute of Hydraulic and Hydraulics Automation, introduced the research results on the stability of the calibration coefficient of the flowmeter in detail and introduced the measuring instruments such as the velocity meter and the friction distance meter. Participants on the subject of the research results after serious review that: 1. The research project after more than 10 years of discussion, and through more than 12,000 large number of sink test data statistics, analysis, proof of the large amount of information provided for the future A large number of reduced flow meter tank
