VEGA VEGASON 71 - 1 … 75 - 1 - Manual (Page 41)

Limitation of the operating range
71 - 1 … 75 - 1 41
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)
Programming example:
Indication of distance in m ........................................ • can be indicated in mode 1 - 05
Indication of gain in dB ............................................. • can be indicated in mode 1 - 06
Start of operating range ........................................... • mode 1 - 07, is here indicated as programming
example
End of operating range ............................................. • select mode 1 - 08 in MODEFIELD
• program 14.00 m in PARAMETER FIELD
• then store with STO-button
0 m
