Operating range
MODE 1 - 05 … 1 - 08
The operating range can be limited in this mode by
programming of
-
start of operating range and
-
end of operating range in case of failure.
Echoes outside this limitation are ignored, e.g.
-
false echoes in the narrow range
-
multiple echoes by reflection in empty vessels
(see programming example)
Note:
In case of multiple reflections, a limited operating
range may not be sufficient. The end of operating
range should be programmed min. 10 % > than the
max. vessel height.
min. distance (e.g. VEGASON 74 - 1)
max. vessel distance
end of operating range
max. distance (e.g. VEGASON 74 - 1)
