Background
With the continuous promotion of industrialization, the domestic water consumption of urban and rural residents is continuously increased, and the discharge amount of domestic and industrial wastewater is rapidly increased. And due to the fact that the urban and rural drainage pipe networks, the ditches and the rivers lack unified planning and construction due to the fact that infrastructure is imperfect, the conditions of the urban and rural drainage pipe networks, the ditches and the rivers lack effective monitoring. The problems of no rain and sewage separation, low utilization rate and efficiency of urban and rural pipe networks, black and odorous water channel and river siltation, rain waterlogging and the like become increasingly prominent, and the inconvenience is brought to life and travel of urban and rural residents due to pipe network siltation, black and odorous water channel and river siltation and urban waterlogging, and a lot of potential safety hazards are generated. The real-time monitoring of the flow of the drainage pipe network can provide visual and effective data basis and theoretical basis for urban planning and design, the Doppler ultrasonic flowmeter is mostly adopted for monitoring the flow of the drainage pipe network at present, the flowmeter generally adopts a water level flow velocity method to calculate the flow of the pipe network, and the authenticity of the flow is closely related to the water level. Because the water level measurement generally adopts this kind of sensor precision height of silicon pressure sensor, but the stable performance is installed and is generally pressed close to the bottom of the tube and is easily silted up and lead to measuring error, and the silicon preforming easily produces linear drift under the condition of long-term pressurized simultaneously.
