About :
The radar sensor is a measurement device for the contact-free determination of the flow velocity and depth of open rivers and channels. The sensor detects the surface flow velocity by the principle of the Doppler frequency shift. Due to the contact-free measurement method the device can be installed on extension arms without costly structural measures in the channel or river. This also has the advantage that the sensor is located outside the danger area of flood events and that it requires little maintenance over many years.
