Description

DISCHARGE MEASUREMENT FOR OPEN RIVERS WITH EXTERNAL WATER LEVEL DATA

Innovative radar sensor for non-contact discharge measurement of rivers, open channels and canals with the possibility to use and integrate external water level data.

FIELDS OF APPLICATION

The RQ-30L is mainly applied where existing measuring sites (e.g. gauging sites) should be upgraded in terms of quality without the need for big investments. While the water level can be measured as before, the radar sensor improves the accuracy by additionally determining the surface flow velocity. Therefore the RQ-30L is a very effective extension to all sites where the water level should (or must) be measured by a separate instrument other than the RQ-30.

MEASURING PRINCIPLE

The water level (water gauge) is determined by any measurement device other than the RQ-30L and provided to the same as an analogue data input for the discharge calculation.
