SYSTEM AND DEVICE FOR DETERMINING THE VALUE OF A LOCAL DEFORMATION PARAMETER OF A LIQUID STORAGE TANK AND USE OF SAID DEVICE

摘要

The system (100) for determining the value of at least one parameter of a liquid storage tank, such as a local deformation of the tank, for example, is characterised in that it comprises: - a liquid storage tank (115); and - a removable device (120) for determining the value of at least one parameter of a liquid tank, which device comprises: - an attachment means (125) to the inside of the tank, for example to a mast positioned inside the tank and in the vicinity of an upper wall (130) of said tank, said attachment means supporting: - a multi-directional laser emitter (110); - a receiver (135) of the light emitted by the laser; - a photodetector (140) converting the received light into an electric signal; and - a means (145) for detecting a relief inside the tank as a function of signals converted by the photodetector; - a means (146) for determining a topography of at least one wall of the tank as a function of at least one detected relief; and - a means (150) for determining the value of each local deformation parameter as a function of the determined topography.
