摘　　要：时差法测流技术广泛应用于管道流量测量,产品应用很成熟,在水文行业由于系统技术的局限性和行业的复杂性,应用较少。近几年国产声学时差法测流系统技术日益完善,在浙江省水文测流断面中应用逐步增多,经过3处大中小断面和不同水文特性的国家基本水文站在线测量数据与人工实测数据进行对比分析,其中2处达到二类精度站要求,1处达到一类精度站要求,可以满足水文测验要求。该系统可应用于大中小河流,流态紊乱、有正逆流的感潮河段也可使用。The time difference method flow measurement technology is widely used in pipeline flow measurement,and the product application is very mature.However,due to the limitations of system technology and the complexity of the industry,its application is limited in the hydrological industry.In recent years,the technology of domestically produced acoustic time difference method flow measurement system has been increasingly improved,and its application in hydrological flow measurement sections in Zhejiang Province has gradually increased.After comparing and analyzing the online measurement data and manual measurement data of the system in three large,medium and small sections and national basic hydrological stations with different hydrological characteristics in Zhejiang Province,two of them meet the requirements of Class II accuracy stations,and one meets the requirements of Class I accuracy stations,which can meet the requirements of hydrological testing.This system can be applied to large,medium,and small rivers,as well as tidal sections with turbulent flow patterns and positive and negative currents.
