1. Measure length "l" of the wall.
2. Determine the response level "h" that corresponds to the permissible
filling degree: h = l x 0.95.
3. Measure the vertical distance between the bottom edge of the screw fit-
ting of the product and the upper edge of the tank wall (where the roof
begins) to get auxiliary dimension "c".
4. Calculate the adjustment dimension X: 
b = l + c
X = b - h
