[54] IDENTIFYING UNDESIRED CONDITIONS IN THE FUNCTION OF A FLOATING ROOF OF A TANK
[57] Abstract: A method for identifying an undesired condition in the function of a floating roof of a tank, the method comprising determining a filling level of a product in the tank, detecting a reference distance between a reference position on the roof and the surface using a level gauge mounted on the roof, forming a reference distance deviation as a difference between the reference distance and an expected value, and comparing the reference distance deviation with a specified range. If the reference distance deviation is outside the specified range, a data set including the reference distance deviation and the filling level is stored. These steps are repeated for a plurality of points in time, and the undesired condition is then identified based on stored data sets of reference distance deviations and filling levels.
