  • Coriolis mass flow measuring device
    Patent number: 7181982
    Abstract: A Coriolis mass-flow/density meter includes at least one measuring tube through which a two, or more, phase medium during operation. A support means of the Coriolis mass-flow/density meter is fixed to an inlet end and an outlet end of the measuring tube and thus holds the tube such that it can oscillate. During operation, the measuring tube is made to oscillate with mechanical oscillations, especially bending oscillations, by means of an exciter arrangement. Additionally, the Coriolis mass-flow/density meter includes means for producing measurement signals (xs1, xs2) representing inlet end and outlet end oscillations of the measuring tube. An evaluation electronics produces an intermediate value (X?m) derived from the measurement signals (x1, xs2) and representing a provisionally determined mass flow rate.
