The system of one master-radar sensor and several slave-radar sensors is a solution for measuring discharge in wide rivers with inhomogeneous distribution of flow velocity. This system measures velocity at several spots throughout the whole water cross-section, ensuring a high accuracy of discharge measurement even in wide water bodies.
One advantage of this system is its high accuracy, which makes it ideal for use in rivers with inhomogeneous velocity distribution. Additionally, the system requires only one water level measurement and multiple individual velocity measurements, making it a cost-effective solution.
The system utilizes the well-proven RQ-radar technique for non-contact measurement, ensuring a maintenance-free system that is flood-proof. No structural work is necessary in the water, making installation simple and easy. The system also recognizes flow direction and hysteresis effects and can measure in tidal waters and backwater situations.
Another advantage of the system is its ability to measure even where weed growth prevails, and the sensor is not affected by turbidity. The measuring range is 0.08 to 16 m/s, depending on the flow conditions, and the system can provide analog outputs from 4 to 20 mA.
Overall, the system of one master-radar sensor and several slave-radar sensors is a reliable and accurate solution for measuring discharge in wide rivers with inhomogeneous distribution of flow velocity. Its non-contact measurement technique, low maintenance requirements, and simple installation make it a valuable tool for river management and monitoring.
