Service Manual 6 - 69
☛ For a Stilling well application, program following entities:
6.5.2.3 Level Check
With the
[Accept reference] command, the gauge’s innage or ullage value
is initialized in accordance with the before programmed reference data.
From here the gauge will follow all relative level changes.
This command will only be accepted if the product level is
<GOOD>.
This command also puts the SmartRadar FlexLine in accurate level
measurement mode, so this command MUST be given!
The
[Accept reference] command can handle either a reference innage or a
reference ullage level. To adjust to an innage level fill in entity
[Reference
innage]
, to adjust to an ullage level fill in entity [Reference ullage]. This level
value is mostly obtained by a manual level measurement (hand dip);
see FIGURE 6-9.
When all values are sent to the SmartRadar FlexLine, the
[Accept
reference]
command can be given.
When an innage or ullage reference value is not available, the
[Accept
reference]
command must be given without filling any of these entities.
The SmartRadar FlexLine will now be put into accurate level
measurement mode.
[Nozzle length] Needs only to be set if the antenna is installed
inside the nozzle.
Entity Name Explanation
[Tank bottom position] The gauge uses this information to calculate
the level (innage), and to determine the
position of the bottom reflection (part of peak
selection).
[Maximum Safe fill] With this entity the gauge checks if the
programmed upper measuring range is valid
(
[Minimum measurable distance] at least 
<0.5 m> from the antenna).
[Upper reference position] This entity is only used if “ullage” is to be read
from the SmartRadar FlexLine. The ullage is
then calculated from the measured level
(innage) as
[Upper reference position]-measured
level.
[Stilling well diameter] The inner diameter of the stilling well
