摘　　要：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。There exist some problems in monitoring the flowrate of sewerage in drainage pipe,which include the difficult installation of devices and low accuracy of monitoring.To solve these problems,it was supposed to use the immerged double-beam doppler flowmeter for surveillance of sewerage flowrate.The installation method of this device could let it be installed easily in the drainage pipe through inspection well.In addition,its double-beam doppler signal could remove the influence of the vortex and turbulence in the pipe on the surveillance accuracy.This paper introduced the component,working principle,working process and installation requirements of the immerged double-beam doppler flowmeter as well as its practical engineering application.
