In applications such as underground manhole water-level remote sensing, the product’s non-contact ultrasonic ranging capability enables accurate water-level measurement and effectively handles conditions involving water quality, impurities, and floating debris. When deploying the device, it is important to account for the issue of the sensor entering an ultrasonic blind zone at high water levels.

奎屯DG-RAS-R-S20L10 Radar Ultrasonic Flow Meter

The product employs a dual‑mode sensor—combining underwater ultrasonic Doppler flow velocity and radar Doppler flow velocity—to measure manhole flow. The sensor also incorporates radar, pressure, and conductivity modules to acquire water level signals. The RTU integrates a power management module, a sensor drive module, a power supply management module, and a communication module.

奎屯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.
