Abstract: The invention relates to a mass flow meter operable on the Coriolis principle having two rectilinear juxtaposed parallel arranged measuring tubes mechanically interconnected at their ends. An oscillator between the tubes produces opposite oscillatory movement of the tubes with a harmonic oscillation superimposed on the fundamental oscillation. Sensors between the tubes on opposite sides of the oscillator sense relative movement between the tubes and generate signals corresponding thereto. A circuit responsive to these signals determines resonant frequencies of the fundamental and harmonic oscillations and derives therefrom a correcting value which gives effect to axial stresses in the measuring tubes to determine a corrected mass flow.

Abstract: A mass flow meter based on the Coriolis principle. The meter has two rectilinear measuring tubes juxtaposed in parallel and mechanically connected at adjacent ends thereof. An oscillation generator is connected to the tubes between the ends thereof for driving the tubes in opposite directions. A sensor connected to the tubes on opposite sides of the oscillation generator sense and signal relative oscillations of the tubes which is indicative of the flow through the tubes. The measuring tubes have different bending strengths in two perpendicular axial planes thereof to reduce the amplitudes of vibration in the plane normal to the plane of interest. Individual masses applied to the measuring tubes cause the natural frequency of at least the first mechanical harmonic of the measuring tubes to differ from the natural frequency of the mechanical fundamental counter-oscillation by a factor x which differs from a whole number by at least 0.1.

Abstract: The invention relates to an apparatus for measuring a force wherein the force to be measured is applied to a beam in an axial direction. Oscillating forces applied transversely to the beam sets the beam in its resonant state and the resulting resonant frequency is an indication of the magnitude of the force.

Abstract: The invention relates to a mass flow meter which operates on the coriolis principle. The meter has two straight and parallel measuring tubes with two axially aligned compensating supply and discharge tubes arranged in parallel to the measuring tubes. The compensating tubes have approximately the same coefficient of expansion as said measuring tubes. A mounting member having supply and discharge passage has the juxtaposed ends of the compensating tubes connected thereto. The opposite ends of the compensating tubes connect to the respective juxtaposed ends of the measuring tube. An oscillator drives the measuring tubes in opposite directions and sensors are provided for detecting movements of the measuring tubes from which mass flow can be determined.
