System and method for measuring a mass of fuel within a variable geometry container
First Claim
1. A system for measuring a mass of fuel contained in a variable geometry container, comprising:
- 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,at least one three-axis load cell coupled with the rigid support, wherein the three-axis load cell provides a first set of three signals, each one of the three signals having a magnitude proportional to the force exerted by the container assembly in one of three perpendicular directions of the space,at least one three-axis accelerometer coupled with the rigid support, wherein the three-axis accelerometer provides a second set of three signals, each one of the three signals having a magnitude proportional to the acceleration to which the container assembly is subjected in one of the three perpendicular directions of the space, anda signal processing device configured to convert the first and the second set of signals to obtain force and acceleration data, for each one of the directions of the three perpendicular directions of the space, and also configured to calculate a measure relative to the mass of fuel contained in the variable geometry container.

Abstract
A system and method for measuring a mass of fuel contained in a variable geometry container. The container comprises a container assembly, formed by a variable geometry container disposed on a rigid support, a three-axis load cell coupled with the rigid support and providing a first set of three signals with a magnitude proportional to the force exerted by the container assembly, a three-axis accelerometer coupled with the rigid support and providing a second set of three signals with a magnitude proportional to the acceleration to which the container assembly is subjected, and a signal processing device configured to convert the first and the second set of signals into force and acceleration data, for three perpendicular directions of the space, and configured to calculate a measure relative to the mass of fuel contained in the variable geometry container.

9. 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. - View Dependent Claims (10, 11, 12, 13)
