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.
