摘要： A Coriolis flow sensor with at least one vibrating flow tube through which a medium flows, includes elements for exciting the tube, and optical detection element for determining the movements of one or several points of the tube based on the principle of reflection of a light beam against the photosensitive surface of a light sensor. The light beam is directed at the tube wall, at a layer provided on this wall, or at an element fastened against this wall, wherein elements for shaping the beam are arranged for making the convergence of the beam in the direction of movement of the tube associated with the Coriolis forces smaller than the convergence in the direction of movement of the tube associated with the excitation forces. The sensitivity in the detection of the small movements of the tube caused by the Coriolis forces is enhanced.

摘要： A flow measuring system of the Coriolis type for measuring a mass flow, with a flow tube and with excitation means for causing the flow tube to rotate about an axis of rotation, with at least three sensors arranged free of the flow tube for generating analog signals that correspond to the movement of the tube, and with means for digitizing the analog signals and for computing the mass flow from the digitized sensor signals. The computation means are arranged for using exclusively the time information from the sensor signals. The accurate time information of the sensors is used by algorithms in digital electronic circuits for accurately determining the ratio between amplitudes due to excitation and those due to Coriolis forces. The mass flow is derived from this ratio.

摘要： A mass flowmeter of the Coriolis type with a tube through which a medium flows during operation and with excitation elements for causing the entire tube or part thereof to perform a rotational vibration about a primary axis of rotation during operation. The excitation elements are electromagnetic and do not make contact with the tube during operation and have no components that are fastened to the tube. The tube is made of an electrically conducting material, and the excitation elements include first members for causing an electric current to flow through the tube during operation and second elements for generating a magnetic field at the area of a portion of the tube. The magnetic field is perpendicular to the direction of the current and in operation either the current or the magnetic field changes its sign periodically.
