Tanks with inner shell
For tanks with an inner shell (e.g. cylindrical horizontal or tanks welded together in the
basement) the data in steps "4.Tank volume" and "5.Internal tank height" must be corrected.
Example: Wall thickness of the inner shell approx. 0.5 to 1.0 cm
Reduce the entry for "5.Internal tank height"
by approx. 20 %
Entry "4.Tank volume"
tank to 10 m³: Reduce vol. by 3.0 %
Tank to 20 m³: Reduce vol. by 2.5 %
Tank to 50 m³: Reduce vol. by 2.0 %
Tank to 100 m³: Reduce vol. by 1.5 %
