Abstract
The process for generating at least one warning signal relating to the level in a tank (3) for storing a product (4) comprises the following steps: PA0 the storage level of the product in the tank, together with the values of the product quantity consumed during predefined time intervals are determined, PA0 these values are placed in memory together with the associated measurement instants, PA0 at other successive instants PA1 the values placed in memory of the product quantity consumed are used to calculate a value of the estimated quantity of product which will be consumed in the future, PA1 this estimated value is subtracted from the last measurement value so as to obtain an estimated value of the storage level at a future instant, PA1 this estimated value of the storage level is compared with a preset threshold, and PA1 a warning signal is generated if the estimated value is less than the preset threshold.
