1 Min. level = max. measuring distance
2 Max. level = min. measuring distance
For this adjustment, the distance is entered when the vessel is full
and nearly empty. If these values are not known, an adjustment with
other distances, for example, 10 % and 90 % is also possible. Starting
point for these distance specifications is always the seal surface of
the thread or flange.
