The exact and real time knowledge of water discharge is of central importance in the fields of hydrography, water storage management, irrigation and for the early detection of floods. It is essential in hydraulic engineering and water resource management and is the basis for hydrological modelling and simulation.

The RG-30+C sensor is a continuous measurement device for the contact-free determination of the water speed and water level of open rivers and channels. It combines two sensors in one system. The first determines the water level by measuring the transit time of a radar signal. The second simultaneously measures the flow velocity of the water surface by means of the Doppler frequency shift.

Due to the contact-free measurement method the RG-30+C can be installed on extension arms or cable ways without costly structural measures under or inside the water. This also has the advantage that the sensor is located outside the danger area of flood events and that it requires no maintenance over many years.

Harnessing the Power of AI and Machine Learning for Precision Measurements and Unmatched Reliability. (optional)

Unlocking new frontiers in data accuracy, the RG-30+C integrates cutting-edge internal AI and machine learning algorithms, ensuring unparalleled precision even in challenging environmental conditions. (optional)
