Installation in closed containers
When installing in closed containers, the sensor face must not be flooded. Use a pipe socket if the
distance cannot be maintained in any other way.

Vessel installations
Vessel installations can cause strong false echoes that are superimposed over the useful echo
signals (roughness on container walls, various partitions, agitator 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 (di-
rect the agitator paddle to the ultrasonic signal beam).
