Linear 
Default setting 
linear tank, rectangular tanks, vertical cylinders, 
basement-welded steel tanks. 
Cylindric 
horiz. 
cylindrical tank (optionally, see Cyl. > 50 m³), 
horizontal cylinders; tubular tanks, max. 45 m³; typical 
shape for steel outdoor or buried tanks. 
Ball-shaped 
spherical tank; buried tanks with spherical 
basic shape; frequently plastic buried tank (GRP). 
Oval 
oval basement tanks; typical shape of GRP 
tanks and single-walled sheet metal tanks 
Convex 
Plastic battery tanks, convex, 
slightly convex shape, alternative to linear 
Concave 
Plastic battery tanks, concave, 
slightly concave shape, alternative to linear 
Holed 
plastic 
Plastic tank with recess 
Plastic tank with a large recess (hollow) in the center 
(without tape bindings) 
Cyl. 
> 50.000 L 
large cylindrical outdoor tank 50000 litres to 100000 
litres; a special bearing chart conversion table can be 
ordered specifically for large cylindrical tanks of 50 m³ to 
100 m³. 
Metal oil 
tanks 
Plate tank or plate tank battery 
linear side walls, with semicircular arc up and down. 
Bearing 
chart 
Enter a special tank shape from existing bearing chart. 
For this purpose, up to 16 value pairs (height in mm + 
volume in L) can be entered. 
Before the value pairs are entered, the values for the 
tank volumes must be entered in step 4 and for the tank 
height in step 5.

max. inside height of tank  the 
max. tank volume (= “5.Tank height”) 
is allocated automatically and does 
not have to be entered. 
Not all 15 intermediate value pairs (Index: 1 - 15) have to be entered. 
A linear interpolation is made between 2 interpolation values. For a linear range of the tank 
geometry it is sufficient to enter a lower and an upper value pair.
