保定DG-RDS-S10L20 Radar Doppler Flow Meter

This is a non-contact flow‑measurement method. The Doppler radar integrates a microstrip antenna, RF circuitry, and a signal‑processing module, enabling direct acquisition of surface flow velocity and water‑level information. The velocity radar measures flow by exploiting the Doppler effect caused by the movement of surface waves; it is recommended to mount the velocity‑sensor module facing upstream. When the water flow approaches the sensor, a positive velocity reading is displayed. The water‑level radar can acquire water‑level data; when combined with bottom‑elevation data, it allows estimation of the cross‑sectional flow area. By integrating this with flow‑velocity measurements and applying hydraulic modeling, flow‑rate data can be derived.

Product Description

Measurement principle

This is a non-contact flow‑measurement method. The Doppler radar integrates a microstrip antenna, RF circuitry, and a signal‑processing module, enabling direct acquisition of surface flow velocity and water‑level information. The velocity radar measures flow by exploiting the Doppler effect caused by the movement of surface waves; it is recommended to mount the velocity‑sensor module facing upstream. When the water flow approaches the sensor, a positive velocity reading is displayed. The water‑level radar can acquire water‑level data; when combined with base‑station measurements, it allows estimation of the cross‑sectional flow area. By integrating this with flow‑velocity data and applying a hydraulic model, the discharge can be determined.

Key Features
