| 摘 要： | 声学多普勒剖面流速仪(ADCP)设备在水文领域保有量大、应用广,但如何对其进行量值溯源,确保现场测量数据准确可靠是用户非常关注的问题。分析ADCP的测试现状,阐述ADCP的6个测试参数,分析出流速测试是核心;利用微纳气泡作为示踪粒子,尝试解决静止水体无反射粒子的问题,为ADCP流速测试提供支撑;以TRDI的WHR600-1型ADCP为例,说明ADCP流速测试过程和试验数据处理方法。得出微纳米气泡是ADCP拖曳水槽水跟踪测试较好的示踪物质,进而实现ADCP水跟踪流速测试。为拖曳水槽ADCP测试改造建设提供技术思路,并给出实验室测试建议。

| Abstract: | The ADCP equipment has a large quantity and wide application in the hydrological field,but how to trace its value to the source and ensure the accuracy and reliability of on-site measurement data is a very concerned problem for users.This paper analyzed the testing status of acoustic doppler profiler current velocity meter(ADCP),expounded the six testing parameters of ADCP,and pointed out that velocity measurement is the core.The micro nano bubble was used as a tracer particle to try to solve the problem of no reflecting particles in still water,which provided a strong support for the ADCP velocity test.Taking the WHR600-1 type ADCP of TRDI as an example,the flow rate testing process and experimental data processing method of ADCP were illustrated.Finally,it is concluded that micro-nanobubble is a good tracer for ADCP water tracking test and the conclusion of ADCP water tracking velocity test is realized. |
