Note: The measured displacer weight should not differ more than 0.1
grams from the engraved displacer weight (0.1 gram measuring error by
the displacer weight results in a density error of 0.5 kg/m
If it is more than 0.1 grams, re-calibrate the force transducer and/or
check the drum unbalance.
The items mentioned in this section are common for the Tank Profile
and Interface Profile measurement.

Description
Units: [gram]. Enter the weight of the displacer.
This is engraved on the displacer.
Units: [cm 3 ]. Enter the volume of the displacer.
This is engraved on the displacer.
Number of levels where a density measurement is
performed (1-50). The default value is 10.
Units: [m 2 ]. Wire cross sectional area (0.25 * π *
diameter 2 ). The default value is 3.1416x10
Note: This parameter is automatically set correctly
when the correct [Measuring range and wire type]
is chosen (refer to section 7.4.
Enables or disables compensations on the density
calculations:
•
Tilt: compensates for dynamic tilting of the
gauge by measuring the displacer weight
in vapour before the actual density
measurements.
Note the compensation will only be
performed if the displacer weight can be
measured in vapour, so there must be
enough space. TP requires at least a full
drum rotation +0.25m. IP requires 0.25m.
•
Unbalance: compensates for the
unbalance of the drum. This compensation
requires a valid unbalance table (refer to
section 9.1.3)
•
Displacer volume: compensates for
hydrostatic pressure on the displacer and
thermal expansion of the displacer.
In high pressure applications (spheres or bullets)
this entity should reflect the pressure in the storage
tank. The default value is atmospheric pressure
(101325 Pa).
