• If the level sensor is mounted to
bottlenecks and places with bar
-
riers, or near uneven walls or the
filling area, where the transmis
-
sion signal could be distorted, we
recommend using a guide tube
(acoustic horn). The tube must be
made from a single material with
a smooth inner surface (see im
-
age 12a, 12b ). The minimum tube
diameter must have the dimen-
sion "b" according to image 4 on
page 5. After installing, you must
perform the procedure "LEARN-
ING".
We recommend consult-
ing with the manufacture on
the construction of the guide
tube.

•
The measuring device shall not be installed in
places with direct sunlight
and shall be
protected against weather conditions. If installation in places with direct sunlight is inevi-
table, it is necessary to mount a shielding cover above the device (Fig. 12).
•
It is advisable to keep cable under the
cable gland
(sagging down) as shown in Fig. 13 to
prevent penetration of moisture. Rain and condensing water can be therefore drained
away freely.
•
The cable gland as well as the connector shall be
tightened sufficiently
to prevent pen-
etration of moisture.
