Fluid tank with integral fluid quantity gauging

摘要

A gauging system for a fluid tank includes means for determining fluid pressure data for the tank; means for determining acceleration data of the tank; and means for determining quantity of fluid in the tank as a function of the pressure and acceleration data. A method for determining quantity of fluid in a tank is also provided and includes the steps of: a. determining an orientation vector for each of a plurality of sensing areas of the tank; b. producing an output corresponding to pressure of the fluid on each of the respective sensing areas; c. determining an acceleration vector of the tank; and d. calculating quantity of fluid in the tank as a function of the pressure output signals, the orientation vectors and the acceleration vector.
