•
Install the level meter in the vertical position into the upper lid of the tank or reservoir using a weld-
ing flange, a fastening nut or a flange so that the
level meter axis is perpendicular to the surface level
of the measured liquid (Fig. 1).
T he min. dimensional parameters to install the level
•
meter into a lid or a ceiling of a tank are given in Fig. 3.
•
When installing in an open channel (reservoir, drain
etc.), install the level meter onto a bracket as close as
possible to the expected max. level.
•
In connection with the measurement principle, no sig-
nals reflected in the area immediately under the level
meter can be evaluated. The zone (Fig. 2) determines
the min. distance possible between the level meter
and the highest surface level. The min. distances to
the medium are given in the chapter "Specifications".
•
It is necessary to install the level meter so that the
bin level cannot interfere with the dead zone when
filled up to the maximum. If the measured level inter-
feres with the dead zone, the level meter will not work
properly.

•
If the maximum surface level in the tank interferes with the dead zone, the level meter has
to be mounted into a higher installation neck. In this way, the tank can be fi led nearly up to
the maximum volume. The inner neck surface has to be even and smooth (without edges and
welded joints); the inner edge should be rounded where the ultrasonic wave leaves the pipe. The
neck diameter should be as large as possible but the neck height should be as low as possible.
Recommended dimensions of the input neck are given in Fig. 4.

b – Neck width
