RQ-24 Radar Measurement by SommerThe RQ-24 sensor enables the continual measurement of flow velocity and level and automatically calculates the discharge quantity of surface waters. Based on the non-contact measurement principle of Doppler radar technology and time delay measurement, the quality of the RQ-24’s measurements and its flexibility of deployment make it unique in its sector.

¶ Non-contact = fail-safe = low maintenance

¶ Measures even in case of floodwaters

¶ Low power consumption – self-powered with solar

¶ Recognizes riverbed change immediately

¶ Measures at sites difficult to access

¶ Integrates into any measurement network system

¶ Easy installation
