On‑site Installation Case of Doppler Flowmeter for River‑entering Drainage Outlet

The Doppler flowmeter is deployed at river‑entering sewage outlets for real‑time flow monitoring. Based on acoustic Doppler principle, the probe is installed inside drainage pipe to collect water level and flow velocity, automatically calculating instantaneous flow and total discharge volume. It adapts to complex conditions with sediment, floating debris and variable water quality under partial‑filled pipe status. Data is wirelessly uploaded to monitoring platform for flow statistics, data storage and over‑limit early warning. It provides reliable support for sewage tracing, water environment treatment and discharge control. Featuring simple installation and high protection grade, it suits harsh outdoor environment with low maintenance. It is widely used for industrial and municipal drainage outlets to realize digital supervision of river and lake water quality.
