珠江委水文局首次从美国RDI公司引进的声学多普勒测流系统(ADCP)近日通过现场验收。经技术培训和比测后,将正式投入使用。ADCP是当今世界先进测流仪器的代表,专门用于测量河流、水渠或狭窄海峡的流量。利用声学多普勒测流系统既能测流速剖面又能测水深,将两岸间各测点的流速剖面和相应深度进行积分计算,即可由计算机算出流量值。用户可灵活地利用各种运载工具,将仪器从此岸移至彼岸,就能在几分钟内完成精确的流量测量,其流量测量的重复性优于2%,且测量精度
Acoustic Doppler Flow Measurement System (ADCP), first introduced by Pearl River Commission Hydrology Bureau from American RDI Corporation, passed the site acceptance recently. After technical training and testing, will be officially put into use. ADCP is the representative of today’s world-advanced flow measurement instruments designed to measure the flow of rivers, drains or narrow straits. Acoustic Doppler flow measurement system can not only measure the velocity profile but also measure the water depth. Integrate the velocity profiles and the corresponding depths of the measuring points between the two banks so that the flow values can be calculated by the computer. Users have the flexibility to use a variety of vehicles, the instrument moved from shore to shore, can be completed within minutes accurate flow measurement, the flow measurement repeatability of better than 2%, and the measurement accuracy
