If the emitted acoustic signal of the level meter is affected by near objects (roughness on walls
of the tank, various partitions, mixers etc.), it is necessary to map false reflections by activating
the mode "TEACHING". In case of installed mixers, it is necessary to put the mixers to position
under the level meter (direct the mixer paddle to the ultrasonic signal beam) (Fig. 5 and 6).

Do not install the level meter in or above the filling point (Fig. 7).

In case the level of bulk solids being the
measurement range is reduced Due to absorp-
tion of acoustic waves by medium, the
shortening of the measuring range can be
reduced by up to 50% depending on the
medium and the particle size. We therefore
recommend selecting a level meter with greater
range than the maximum range of measuring
the medium. It is also recommended to use a
directional horn (see image 8), which will
increase the range the measuring range,
(concentrates acoustic energy) while pre-
serving the same beam angle, and improves
the sensitivity when receiving the reflected
echo. We recommend to consult the use with the
manufacturer.
