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.

Applications/Examples of results
- River flow velocity measurement (capable of both low and high flow observations) With a unique signal processing algorithm, stable measurements can be conducted even during heavy rain or snowfall (proven results). - As a sensor for gate opening and closing It can measure the direction of flow (downstream and upstream) and flow velocity, making it useful as a switch for gate opening and closing.
Detailed information
-
The sensor is lightweight and compact (the main unit weighs 5.6 kg), so installation work requires little effort. The measurement and power supply units are also compact, allowing for pole mounting. It is capable of operation without power using a small solar panel and can be installed on railings as well. Additionally, since the data processing unit is integrated with the sensor, there is no need for a storage cabinet for the processing unit.
-
Even with rainfall intensity equivalent to 60mm/h, there is a proven track record of stable data acquisition. *In the demonstration field of rivers in Kawasaki City.
-
It is possible to distinguish and measure both positive and negative flows. Detection and analysis of river backflow can also be performed.
-
Continuous recording of flow rate and water level data is possible with the dedicated data logger (CSM-MRL-8). By connecting a modem to the data logger, data can be checked and downloaded remotely. The system can be powered by solar panels.
