摘要： This method of fixing the ends of measuring tubes in associated transition pieces of a Coriolis-type mass flow sensor eliminates the risk of stress-corrosion cracking in these areas as completely as possible. The ends of the measuring tubes are inserted into associated bores of the respective transition pieces and are press-bonded to the walls of the respective bores without heat supply using a rolling tool which is inserted into the respective ends.

摘要： The present Coriolis mass/flow density meter and method for measuring a mass flow rate of a medium flowing through a flow tube of a Coriolis mass flow meter provide measurement results which are independent of the current velocity field of the medium to be measured. At least one measuring tube is provided, through which the medium flows, which oscillates during operation. A means for measuring the oscillations is arranged at an inlet end of the measuring tube and provides a measurement signal. A second means for measuring the oscillations is arranged at the outlet of the measuring tube and provides a second measurement signal. A third measuring means provides a third measurement signal which represents the current Reynolds number of the flowing medium, Evaluation electronics generate a measurement value representing the mass through-flow. The evaluation electronics also generate a measurement value representing the current density of the medium.

摘要： The measurement transducer includes at least two oscillatably held transducer tubes vibrating, at least at times, during operation, of which at least one transducer tube serving to convey at least a volume portion of a medium to be measured, communicates with a pipeline; as well as at least one transducer element for converting electrical energy into mechanical and/or vice versa. The two transducer tubes are mechanically coupled together by means of at least one, inlet-side, coupling element and by means of at least one, outlet-side, coupling element in such a manner that both the inlet-side coupling element, as well as also the outlet-side coupling element, are subjected during operation repeatedly to deformations which correspond to vibrations of at least one of the two transducer tubes for converting electrical energy into mechanical, oscillatory energy and/or vice versa. The transducer element, especially a transducer element formed by means of a piezoelectric, deformation body, and at least one of the coupling elements, are, at least mediately, mechanically coupled together in such a manner that the transducer element executes, at least in part, oscillatory movements, which correspond with the repeated deformations at least of this coupling element.
