C.1.5 Stillwell
Diameter
Not available. For liquid applications
only.
n/a n/a
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 blocking distance at least 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 58.
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 59.
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.
