Additional information
"Advanced conditions" should only be applied in the "Level" operating mode.
For two-phase media the "Emulsion layer" option ensures that always the total level is detected
(Example: Oil/condensate application).
The "Probe near bottom" option helps to improve the empty detection, especially if the probe is
mounted close to the tank bottom.
