1. A system for determining mass of liquid held in a container under a varying acceleration, comprising a plurality of force-responsive detectors disposed correspondingly at a like plurality of planar surface areas that define the container, each of said detectors sensing the total fluid force exerted across its respective surface area and producing a first electrical signal representative thereof;

  • an accelerometer for sensing said varying acceleration of the container and producing a second electrical signal corresponding thereto; and

    processing circuit means for receiving said first and second electrical signals and modifying each of said first electrical signals by both a corresponding predetermined surface area orientation signal and said second electrical signal;

    said processing means combining the modified first electrical signals to produce a signal representative of the mass of liquid in the container.
