摘要： The device for monitoring the storage level of a product contained in a tank includes a device for measuring the storage level of the product, a central processing unit for utilizing the level read off by the measurement device, a memory for holding at least one storage level threshold, a device for comparing a level value output by the central processing unit with the threshold, a device for triggering a restocking command and controlled by the comparison device, and a device for transmitting the restocking command to a restocking center. It furthermore includes a device for receiving at least one time of information which is issued by the restocking center in response to the transmission of the restocking command.

摘要： 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:the storage level of the product in the tank, together with the values of the product quantity consumed during predefined time intervals are determined,these values are placed in memory together with the associated measurement instants,at other successive instantsthe 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,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,this estimated value of the storage level is compared with a preset threshold, anda warning signal is generated if the estimated value is less than the preset threshold.
