NSTALLATION INSTRUCTIONS
•
Install the level meter in a
using a lug, a fastening nut or a fl ange in such a way that the ULM axis is perpendicular to the
level of the measured liquid (Fig. 1).
•
Minimum
dimension parameters when installing into
a lid or a ceiling of a tank are listed in Fig. 3.
•
When installing in an
and the like), install the level meter onto a console to
the expected maximum level as close as possible.
•
In compliance with the measurement principle, no sig-
nals refl ected in the area directly below the level me-
ter (the so-called dead zone) can be evaluated. The
dead zone (Fig. 2) determines the minimum distance
possible between the level meter and the highest sur-
face level. Medium minimum distance parameters are
listed in chapter on "Technical specifi cations".
•
It is necessary to install the level meter in such a way
that the bin level does not interfere with the dead
zone when fi lled up to the maximum. If measured level
interferes with the dead zone, the level meter will not
work properly.

•
In case the maximum surface level in the tank interferes with the dead zone, the level meter
has to be mounted into a higher installation neck. Subsequently, the tank can be fi lled nearly
up to the maximum volume. The neck's inner surface has to be even and smooth (without
edges and welded joints), the inner edge should be rounded in the position point where the
ultrasonic waves leave the pipe. Choose the largest possible neck's diameter, but keep the
neck's height as low as possible. Recommended dimensions of the neck are listed in Fig. 4.
