Abstract: With the development of modern flow measurement technology and water level transmission technology in recent years, a variety of advanced flow measurement equipment have emerged. Because of the change of flow pattern in different water levels, various instruments play an important role in their respective applicable range. In this paper, based on the practice of flow measurement at Motuo basic hydrological station on the Yarlung Zangbo river, the selection of instruments in various water levels is analyzed from the perspectives of application scope, economic cost and the environmental risk. Then the zoning of large section is proposed, and different flow measurement instruments are used in different zones. Flow measurement instruments, combined with remote transmission technology for water level, enables the realization of intelligent measurement based on zoning in the whole flow measurement process.

摘要： 随着近年来现代流量测验技术及水位传输技术的发展，各种先进的流量测验设备不断出现。在实践应用中，由于高中低水的流态变化，各种仪器在不同的流态发挥着各自的作用。以雅鲁藏布江墨脱基本水文站流量测验实践为基础，从仪器适用范围、仪器应用经济成本、仪器使用环境风险等角度对各个水位范围仪器的选用做出科学的分析，进而提出对大断面进行分区，在不同的区间采用不同的测流仪器，配合以水位远程传输技术，让整个流量测验过程以分区为基础，实现智慧测验。
