    Abstract

    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. More 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.
