NON-CONTACT DISCHARGE RADAR RQ-30 / RQ-30A

NON-CONTACT DISCHARGE MEASUREMENT BY MEANS OF RADAR TECHNOLOGY FOR OPEN RIVERS

The RQ-30 is a sensor for continuous discharge measurement of rivers, open channels, and canals with known cross-section profiles. The sensor uses innovative radar technology to measure velocity, water level, and discharge. It enables reliable, non-contact measurement without the need for structural work in the water.

Description
