The device adopts non-contact measurement, which will not be corroded by sewage and it has greatly reduced maintenance costs. The real-time measured water level, velocity, and flow are transmitted to the monitoring center through RTU, which is convenient for real-time understanding of the operation status of underground pipeline network. It can be used for flow monitoring of smart cities, smart water services, sponge cities, ecological flows, domestic sewage, combined sewage and rainwater pipe networks.
