OTT SVR 100

Fig. 4: Example application 2:

OTT SVR 100 installed on an auxiliary

structure, e.g. a cantilever arm.

The projection of the OTT SVR 100 radar

footprint on the water surface is elliptical.

In the example shown here, the water level

is determined using a contactless OTT RLS

radar sensor.
