Determining system for water inflow and water outflow in sewage pipeline

The utility model relates to a system for determining the amount of incoming water and outgoing water in a sewage pipeline. The utility model aims to provide a system for determining the amount of incoming water and outgoing water in a sewage pipeline, which is simple to operate and high in accuracy, so as to avoid overlarge water circulation pressure and reduce energy waste. According to the technical scheme, the system for determining the amount of incoming water and outgoing water in the sewage pipeline is characterized by comprising an upstream flow meter arranged on the upstream of a to-be-monitored sewage pipe section and used for collecting the upstream flow of the to-be-monitored sewage pipe section flowing into the sewage pipe section; the downstream flow meter is arranged at the downstream of the to-be-monitored sewage pipe section and used for collecting the downstream flow of the to-be-monitored sewage pipe section flowing out of the sewage pipe section; and the data processing unit is connected w
