Additional information
"Many obstacles" option
This option otimizes the signal evaluation for bulk solid applications with a large
measuring range where obstacles generate many interference echos. With this selection
the last echo in the envelope curve will always be evaluated. For strongly damping media
this is always the level echo.
The
Many obstacles
option is only available for bulk solid applications (FMR56,
FMR57).
Preconditions for the application of the "Many obstacles" option
•
Medium type (→ 139)
=
Solid
• Strongly damping medium (e.g. flour, wheat, cereals, ...)
• No multiple echos if the tank is full
• Interference echo suppression only in the near field (ringing area)
• Expert → Sensor → Echo tracking → Evaluation mode = Short time history
"Weak signal" option
This option improves the detectability of small level echos in bulk solid applications with
very weak signal amplitudes.
The
Weak signal
option is only available for bulk solid measurements (FMR56,
FMR57).

Additional information
The level unit may differ from the distance unit defined in the
Distance unit

(→ 127):
• The unit defined in the
