Method and apparatus for forming the calibration chart for the underground fuel tanks
First Claim
1. A method for determining calibration charts used to determine a level and amount of fuel inside underground fuel tanks (1) at gas stations comprising the steps of:
- rotating a laser distance measurement device (2) located inside an empty underground fuel tank (1) via at least one main shaft (14), said rotation being up to 360 degrees in circular direction of B and up to 270 degrees in the upward-downward direction of A,determining distances of the laser distance measurement device (2) from inner walls of said fuel tank (1) for separate points by use of a ray (3) of the laser device,determining an angle X between said fuel tank (1) and a horizontal plane via at least one inclinometer (4),transmitting the determined distances between the laser distance measurement device (2) and the inner walls of the fuel tank (1) measured at separate points and the angle X as measured by the inclinometer (4) to a computer (18) via at least one control unit (8) anddetermining by the computer (18) the calibration chart of the fuel tank (1) using 3D three dimensional) space points determined from the transmitted distances and the angle X along with 3D (three dimensional) modeling of the inside of the tank.

Abstract
The invention relates to the method and apparatus for forming the calibration chart used to measure the amount of fuel inside the fuel tanks (1) which comprises at least one laser distance measurement device (2) positioned inside said fuel tank (1) and measuring the distance between itself and the inner wall of said fuel tank (1) at separate points, at least one main shaft (14) providing said distance measurement device (2) with rotational movement circularly in the direction of B through up to 360 degrees and in the upward-downward direction of A through up to 270 degrees and at least one inclinometer (4) positioned on the surface (9) and measuring the angle X between said fuel tank (1) and the ground on which it is located.
