针对目前污水管道流量监测存在安装不便和测量精度不高的问题,提出将浸入式双束多普勒污水管道流量计应用于污水管网流量监测。该流量计通过浸入式的安装方式,可以方便地通过窨井安装在污水管道中,并利用双束多普勒信号测量,去除管道中涡流、湍流等对测量精度的影响。介绍了浸入式双束多普勒污水管道流量计的系统组成、工作原理、测量过程和安装精度要求,并介绍了其工程应用情况。
In order to solve the problem of inconvenient installation and poor measurement accuracy of sewage pipe flow monitoring, this paper proposes to apply immersed double-beam Doppler sewage pipe flow meter to sewage network flow monitoring. The submersible installation of the flow meter can be easily installed through the shaft in the sewage pipe and the use of dual-beam Doppler signal measurement to remove the pipe eddy currents, turbulence, etc. on the measurement accuracy. The system composition, working principle, measuring process and installation accuracy of the immersed double-beam Doppler sewage pipeline flowmeter are introduced. The application of the project is also introduced.
