FIGURE 6-8 Definition of [Offset to roof]
☛ To get the radar gauge level without any compensations enabled (but
with averaging filter and maximum Safe fill warnings enabled),
program the entities listed in the tables below.
☛ For a Free space application, program following entities:
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.
[Offset to roof] The distance between radar reference and the
tank roof. The gauge uses this information to
determine the position of the echoes caused
by the product and the roof. A positive value
means the roof is below radar reference (see
also FIGURE 6-8).
