Patent ID: 6922150

Claim:
A level gauging system for calculating the level of the surface of a product in a storage room, the system comprising: a first gauging device for calculating a first value of said level and functionally separated from said first gauging device of second gauging device for calculating a second value of said level, characterized in that the first gauging device is adapted to produce a first signal in dependence of a preset first threshold value of said level and to output a first current level value signal, the second gauging device is adapted to produce a second signal in dependence of a preset second threshold value of said level and to output a second current level value signal, and that the system includes an indicating unit adapted to receive at least one of said first value signal and said second level value signal for presenting the value of the current level of said surface, wherein said indicating unit is adapted to receive both the first and second current level value signals and to determine an appropriate value of the presented current level value based on said first and second current level values.
