You as owner/operator/operating company can do the regular in-
spections yourself.

1. Check whether a malfunction is shown in the display.
2. Visually check the connection point of the level probe for
leaks.
3. Check the display value of the filling level, if possible:
a Fill the volume in the tank up to level a with known flow

level.

the technical service.
