LNG TANK BOTTOM VOLUME MEASUREMENT DEVICE AND METHOD THEREFOR

An LNG tank bottom volume measurement device and a method therefor, the method comprising: placing a laser level at the center of a circle at the bottom of an LNG tank, and automatically dividing the tank bottom into eight regions having eight points of intersection; and placing a measurement device at one of vertical lines thereof, such that a laser-generated vertical line is located at a center position on the measurement device. The measurement device is moved such that the height of each measurement point on the tank bottom can be measured, thus providing accurate measurement data and saving time and effort. The invention solves the problem in which conventional tank bottom volume measurement results in inaccurate readings, and requires a lot of time and effort. L'invention concerne un dispositif de mesure de volume de fond de réservoir de GNL et un procédé correspondant, le procédé consistant : à placer un niveau laser au centre d'un cercle au fond d'un réservoir de GNL, et à diviser automatiquement le f
