Not available. For liquid applications
only.

C.1.6 Antenna
Extension
Optional antenna extension. These are
attached between the flange and the
antenna. Each part is 105 mm / 4.1 ¨
long.
min-max:
0 … 5000.00 mm / 0 … 196.85 ¨
0 mm / 0 ¨
C.1.7 Distance Piece Optional distance piece between the
converter and the process connection.
min-max:
0 … 5000.00 mm / 0 … 196.85 ¨
0 mm / 0 ¨
C.1.8 Overfill
Detection
If this function is switched on, the
device will monitor the level even if it is
in the blocking distance. The displayed
output stays fixed at the blocking
distance, but an error message will
warn the user that the silo is
overfilling.
Yes, No No
C.1.9 Blocking
Distance
The distance from the flange to the top
limit of the measuring range (a zone
given by the user where it is not
possible to measure). We recommend
a minimum blocking distance of
300 mm / 12
¨
below the antenna. If the
distance is less than the blocking
distance, the device continues to
display the blocking distance.
min-max:
antenna extension (C.1.6) +
50 mm / 2 ¨… tank height (C.1.2)
0.5 m / 1.6 ft
C.1.10 Reference
Offset
Offset relating to a reference location
(distance). This value is positive when
the reference location is above the
device flange face and negative if
below. For more data, refer to
Distance
measurement
on page 64.
min-max:
-tank height … 50 m /
-tank height...164.05 ft
0 m / 0 ft
C.1.11 Tank Bottom
Offset
Offset relating to a reference location
(level). The device reference point for
this parameter is the bottom of the silo
(set in menu item C.1.2.0). This value is
positive when the reference location is
below the silo bottom and negative if
above. For more data, refer to
Level
measurement on page 65.
min-max:
-tank height...3000 m /
-tank height...9843 ft
0 m / 0 ft
C.1.12 Time Constant Using this function, the device
processes several measurement
readings to filter out disturbances.
Increasing the time constant will
smoothen the integrated readings,
decreasing will roughen the readings.
min-max:
1...100 sec (seconds)
3 sec
C.1.13 Measuring
Mode
This menu item is set by default to
"Direct Measuring" to measure the
level of most tank contents. The device
uses the largest radar signal to
monitor level. If it is possible there will
be an interference signal in the
measurement zone that is larger than
the level signal, select "Direct Plus"
mode. If you select "Direct Plus" mode,
the device locks on the level signal and
monitors changes in level. If the device
then finds larger reflections in the silo,
it will only monitor the largest signal in
a small search zone around the first
reflection found and ignore all other
reflections. The interference signal
must not be near to the level signal.
