Explanation
Determines the tank profile
stop level until where the
density measurements are
performed. The highest is
used, see next entity.
Determines the tank profile
stop level until where the
density measurements are
performed. The highest is
used, see previous entity.
Determines (at a certain level
position) if the density
measurements are done at
only one point at the drum
circumference (unbalance
compensation could help
here) or at multiple points
over the drum circumference
(would filter out drum
unbalance at the same time).
The number of points is
determined by the entity
[Number of tank profile drum
balance points]
This air density is used
during density calculations.
The pressure at the liquid
surface inside the tank.
Note: For pressurized tanks
this should be the value for
the pressure inside the tank.
This command starts a tank
profile density measurement.
The density measurement
positions are equally
distributed from the range:
Product level – [Density TP
start distance] until [Density
TP stop level] or [Default
density TP stop level] with
the number of points defined
by [Number of density
measurements (max 50)].
