Non-contact 24-hour flow velocity observation of rivers and waterways is now possible! A compact and energy-efficient flow meter. Water level observation is also completed with a single unit, and flow rate is calculated and output internally.
The RQ-30 is a radar sensor developed by the Austrian company Sommer that continuously measures the flow rate of rivers and waterways. It is a device that integrates two non-contact radar sensors that measure surface flow velocity and water level (certified for technical compliance). Due to its non-contact measurement, the system is not affected by damage from sediment or floating debris. For example, even in flood situations, it requires little maintenance and provides high reliability. It is equipped with a learning function that effectively removes measurement noise caused by rain and the terrain of the site. The lower limit for detection and measurement is very small at 0.1 m/s, allowing for the measurement of gentle flows. The distance to the water surface ranges from 0.5 m to 30 m (with 35 m and 15 m models also available), accommodating a wide range of measurements from small waterways to large rivers. Its low power consumption makes continuous operation in off-grid environments easy.
