6.1.4 Calculating the fill weight
If a fill volume is available, the device calcu-
lates the fill weight from it using the density.
The fill volume and weight are proportional
to each other.
The level zero is also the reference point for
the fill weight.
6.1.5 Summary of the parameterisation concept
1. The fill height is calculated from the measured pressure using the density and height
offset.
2. The fill volume is calculated from the height using the tank shape table.
3. The fill weight is calculated from the volume using the density.
4. A manual selection determines which of these measurands should be issued at the
current output.
5. The current output is scaled using the parameters "Value at 4 mA" and "Value at 20
mA".
