1. An apparatus for measuring the mass flow rate of a fluid having two flow conduits, each mounted for oscillation about an axis, of a length of each of said flow conduits through which the fluid to be measured is flowed, comprising:

  • (A) a first sensor means for detecting Coriolis force induced distortions of said flow conduits, said first sensor means having at least two sensor means components, said first sensor means components having essentially equal masses;

    (B) a second sensor means for detecting Coriolis force induced distortions of said flow conduits, said second sensor means having at least two sensor means components, said second sensor means components having essentially equal masses;

    (C) a first beam to which are attached at opposite ends a first sensor means component and a second sensor means component;

    (D) a second beam, said beam having a mass essentially equal to that of said first beam, to which are attached at opposite ends of said second beam a first sensor means component and a second sensor means component;

    (E) means for attaching said first beam to a first flow conduit so that the locations where said first beam is attached to said first flow conduit are at essentially equal first distances from the axis about which said first flow conduit is oscillated, and for attaching said first beam to said first flow conduit so that the center of gravity of said first beam in combination with said first and second sensor means components is essentially positioned on the axis about which generated Coriolis forces act; and

    (F) means for attaching said second beam to a second flow conduit so that the locations where said second beam is attached to said second flow conduit are at essentially equal second distances from the axis about which said second flow conduit is oscillated, said first distances and said second distances being essentially equal, and for attaching said second beam to said second flow conduit so that the center of gravity of said second beam in combination with said first and second sensor means components is essentially positioned on the axis about which generated Coriolis forces act.
