Installation Case of Radar‑Ultrasonic Flowmeter for Underground Pipe

The radar‑ultrasonic flowmeter is mounted by bracket above sewage pipe inside manhole. With non‑contact measuring method, it works for partial‑filled pipe flow monitoring without immersing into water. Combining radar and ultrasonic technology, it collects water level and flow velocity to calculate instantaneous flow and total discharge. It is immune to sewage sludge, floating debris and water corrosion. Data is transmitted via 4G to cloud platform for online flow statistics, historical record and over‑limit alarm, providing valid data for pipe‑network maintenance, discharge metering and water‑environment supervision. Easy to install without pipe reconstruction, the device owns high protection grade and good adaptability to damp underground environment with low maintenance. It is widely used in municipal pipe networks, rain‑sewage outlets and industrial sewage outlets.
