Abstract:This paper taking the Gaotuan Pumping Station-Guishan Flow Regulating Valve pipeline section of the Water Diversion to Jiaodong Area Project as an example, this paper designs a set of pipeline water flow monitoring system using WinCC software. By simulating the water flow state and water head changes during the pipeline water filling stage, it realizes real-time monitoring and prediction of water head trends, providing a strong guarantee for the safe and stable operation of the water diversion project.
