System and method for measuring a mass of fuel within a variable geometry container

A method for measuring a mass of fuel contained in a variable geometry container, comprising the steps:

• providing a container assembly formed by a variable geometry container disposed on a rigid support so that a weight of the container rests on the rigid support,
• generating at least a first set of three signals, by means of a three-axis load cell coupled with the rigid support, wherein each one of the three signals has a magnitude proportional to a force exerted by the container assembly in one of three perpendicular directions of a space enclosed by the container,
• generating at least a second set of three signals, by means of a three-axis accelerometer coupled with the rigid support, wherein each one of the three signals has a magnitude proportional to the acceleration to which the container assembly is subjected in one of the directions of the three directions of the space,
• converting the first and the second set of signals into digital data, representative of measured forces and acceleration subjected by the container assembly, for each one of the three directions of the space,
• calculating, for each one of the three directions of the space, a value relative to the mass of fuel contained in the variable geometry container, from the digital data relative to the measured forces and acceleration,
• calculating, a total value relative to the mass of fuel contained in the variable geometry container.
