　　Abstract：Ningxia water network is characterized by large discharge difference, high sediment concentration, long wind period and high wind speed. And it is a lack of systematic research and practice in the installation platform of online flow equipment. According to the characteristics of Ningxia water network and watershed, the installation status and construction requirements of various kinds of non-contact flow automatic online monitoring equipment are analyzed, and the design ideas of installation platform are put forward. This paper focuses on the design of on-line installation platform for non-contact radar wave flow equipment in rivers (ditches and canals) under different cross-section spans and environmental conditions. Research and practice of the installation method are carried out in the hydrological monitoring sections of 4 natural rivers, 17 main water intake channels and drainage channels in the Yellow River diversion irrigation area, to solve the installation problem of automatic flow on-line monitoring equipment of non-contact radar with various equipment types and different span monitoring sections, and to improve the installation reliability, stability and monitoring accuracy of automatic flow on-line monitoring equipment. The research has a certain popularization and application value in the field of hydrological and water resources monitoring in Ningxia and similar areas in northwest China.
