Pipeline Network Water Level, Flow Velocity, and Flow Rate Series
Radar Velocity and Flow Meter
The radar-based flow velocity and discharge meter uses an 80 GHz frequency-modulated continuous-wave (FMCW) millimeter-wave radar for highly accurate measurements. It offers non-contact, stable measurements and supports both single-line and array configurations. This instrument is suitable for monitoring water levels, flow velocities, and discharge rates in urban rivers, outdoor bridges, culverts, drainage networks, flash flood reservoirs, and other similar water bodies.

Product details
Instrument Overview
The radar-ultrasonic Doppler flowmeter integrates radar-based flow measurement, ultrasonic flow measurement, radar-based water level measurement, and static-pressure water level sensing into a single, all-in-one sensor technology. It is suitable for online monitoring in complex or harsh environments such as underground pipe networks for stormwater and sewage, drainage channels, and river discharge outlets.
Product Features
(1) The minimum measurable surface flow velocity is 0.03 m/s.
(2) Built-in anti-interference algorithm, unaffected by adverse weather conditions.
(3) Easy to configure—use the Bluetooth mini-program for parameter adjustment.
