DEVICE FOR MEASURING TANK WALL THICKNESS Russian patent published in 2018 - IPC G01B11/06 

FIELD: measuring equipment.

SUBSTANCE: system for measuring the thickness of the walls of tanks contains an optical system serving to capture light beams reflected from the outer and the inner surfaces of the wall and to focus them on the registration plane of a light sensor. Wherein the optical capturing and focusing system comprises a first lens, the object plane of which is located next to the point of the light beam incident on the wall. In addition, it comprises at least a translucent diffusing screen disposed in the image plane of the first lens, so as to physically represent the light beams collected by the first lens in the form of hot spots (Ti). In addition, the device comprises a second lens, in the object plane of which a scattering screen is mounted, and in the image plane of which a light sensor is mounted.

EFFECT: increasing the high performance for measuring the wall thickness of transparent or translucent tanks for a wide range of tank types.
