On‑site Installation Case of Radar‑Ultrasonic Flowmeter for Drainage Pipe

The radar‑ultrasonic flowmeter is mounted above circular drainage pipe by bracket. As a non‑contact measuring device, its probe does not touch sewage and fits partial‑filled pipe flow monitoring. Integrating radar and ultrasonic technology, it collects water level and flow velocity to calculate instantaneous flow and total discharge. It resists sludge, floating debris and corrosive sewage for harsh pipe‑network working conditions. Data is sent via 4G to monitoring platform for flow statistics, historical data storage and over‑limit alarm, supporting municipal pipe‑network operation, discharge metering and water‑environment supervision. Without pipe reconstruction, it features convenient installation, high protection grade, good performance in damp underground environment and low maintenance cost. It is widely used in municipal rain‑sewage pipes and industrial sewage pipelines.
