Reduces number of field visits and total cost of ownership

By mounting safely above the water surface away from floating debris and by having low-maintenance requirements, the sensor can remain operating uninterrupted for longer periods of time to save on unnecessary field visits and long-term costs.

State-of-art measuring principle technology

Oriented parallel to the main flow direction and tilted against the water surface, the sensor is transmitting and receiving electromagnetic waves. The sensor detects a change in frequency of returning signals if the water surface is rough and in motion (Doppler shift). From this the water surface velocity can be derived.

Leading indicator to detect shifts

If you have a rating curve based on flow meter or ADCP measurements and you are measuring continuous surface water velocity, you can use real measurements to verify the extrapolated part of the rating curve.

Informs when instream velocity measurements may be required

When a shift is detected, depending on the nature and extent of the shift, it can indicate when a field visit is necessary. This ultimately improves data quality by enabling fast response to changes.
