SYSTEM FOR MEASURING QUANTITY OF LIQUID FUEL AND METHOD FOR MEASURING QUANTITY OF LIQUID FUEL

摘要

A system for measuring the quantity of liquid fuel stored in a container accurately, and a method for measuring the quantity of liquid fuel employing that system. When the pneumatic pressure in a first container (3) is lower than a specified level, air is supplied to the first container (3) through a first pipeline by a pressurizing means (6), volume of the supplied air and variation of pneumatic pressure in the first container (3) caused by air supply are detected or calculated, and volume of liquid fuel in the first container (3) is operated from the volume of air and the variation of pneumatic pressure. When the liquid fuel in a second container (4) is lower than a specified level, a specified quantity of liquid fuel is transported from the first container (3) to the second container (4) through a second pipeline (12) by a transporting means (8) and then the volume of liquid fuel in the first container (3) is operated based on the number of times of transportation of liquid fuel. The quantity of liquid fuel being supplied from the first container (3) to the second container (4) can thereby be measured accurately regardless of the shape or inclination of the first container (3).
