The same procedure must be followed for all different levels, with for
instance an interval of 1 meter. Then the following table is obtained:

Example of hydrostatic deformation correction

Calculate a regression line from the level where the tank shell
deviation is approximately 0.5 mm. In this example, the regression line
is calculated from 8 meters level till the maximum level.
Then, the [Hydrostatic deformation factor] becomes: 0.3869 mm/m.
The [Hydrostatic deformation level] is the point where the regression
line crosses the X-axis; in this example at 8.1435 m.
For proper functioning the servo gauge has several protection
mechanisms implemented. For normal operation these protection
