RAF Radar-Ultrasonic Integrated Flowmeter

Operating Principle

The Radar-Ultrasonic Integrated Flowmeter is based on the Doppler effect in physics and integrates radar flow measurement and ultrasonic flow measurement modes, along with a radar-coupled hydrostatic level sensor. This enables accurate flow measurement in both full-pipe and partially filled conditions, while also measuring water level. The instrument calculates flow rate based on an internal hydrodynamic model, providing precise flow information.

Product Application

● Municipal drainage pipeline networks
● Sponge city projects
● Sewage discharge outlets into rivers
● Industrial wastewater discharge monitoring
● Agricultural irrigation and drainage systems
