The transmission aerial has a horizontal opening angle of 12° and the vertical
opening angle is 24°. The resulting sensor radar footprint can be found in the
example applications in Figures 3 and 4 and the table in Chapter 5.1.
A swivel mount allows easy, problem-free installation, even on unsuitable sur-
faces. The electrical connection is via a factory-assembled 12-pin angled con -
nector and a mounting socket.
The cable length between the radar sensor and the data logger can be up to
1000 metres (depending on the wire cross-section used).
The entire radar sensor – provided it is installed as described in these oper -
ating instructions – has a flood-proof design.

In the example shown, the water level is
determined using a pressure probe.
