摘要： A Coriolis measuring transducer comprises a pair of measuring tubes; an exciter; at least two sensors; and two manifolds. Each measuring tube has a first outer measuring tube bend and a second outer measuring tube bend. Each measuring tube pair has a first group of at least two fixing elements and a second group of at least two fixing elements. The fixing elements have, along the measuring tube centerline, a first separation from outer ends of the measuring tube bends of at most 0.7 bend length. The outer measuring tube bends have, in each case, at least one stiffening element, wherein the stiffening elements are arranged between the groups of fixing elements, wherein the stiffening elements have, in each case, a second separation from an inner end of their measuring tube bend of at least 0.2 bend length.

摘要： A measuring transducer includes a support body, a curved oscillatable measuring tube, an electrodynamic exciter, at least one sensor for registering oscillations of the measuring tube, and an operating circuit. The measuring tube has first and second bending oscillation modes, which are mirror symmetric to a measuring tube transverse plane and have first and second media density dependent eigenfrequencies f1, f3 with f3>f1. The measuring tube has a peak secant with an oscillation node in the second mirror symmetric bending oscillation mode. The operating circuit is adapted to drive the exciter conductor loop with a signal exciting the second mirror symmetric bending oscillation mode. The exciter conductor loop has an ohmic resistance RΩ and a mode dependent mutual induction reactance Rg3 which depends on the position of the exciter. The exciter is so positioned that a dimensionless power factor pc 3 = 4 · R Ω · R g 3 ( R Ω + R g 3 ) 2 has a value of not less than 0.2.

摘要： The measuring system includes a transducer apparatus with two tubes. Each tube is adapted to be flowed through by a fluid from an inlet end toward an outlet end and to be caused to vibrate. An electromechanical exciter mechanism excites and maintains mechanical oscillations of each of the tubes, and a sensor arrangement registers mechanical oscillations of at least one of the tubes. The transducer apparatus includes two temperature sensors each being mechanically and thermally conductively coupled with a wall of the tube, wherein each of the temperature sensors registers a measuring point temperature, and converts such into a temperature measurement signal temperature. A measuring and operating electronics (ME) generates a transducer temperature measured value representing a transducer apparatus temperature so that a magnitude of the transducer temperature measured value is greater than a magnitude of the measuring point temperature and less than a magnitude of the measuring point temperature.

摘要： The measuring system comprises a vibration-type measuring sensor, a sensor housing, a magnetic-field detector, and measuring-system electronics electrically coupled both to an oscillation exciter and to oscillation-sensing devices of the measuring sensor. The measuring sensor is inside the sensor housing and the magnetic-field detector is outside the sensor housing. The magnetic-field detector is designed to convert changes in the magnetic field into a magnetic-field signal having an amplitude dependent on a magnetic flux through the magnetic-field detector and/or on an area density of said magnetic flux. The measuring-system electronics are designed to determine, on the basis of oscillation measurement signals of the measuring sensor, the mass-flow-rate measurement values representing the mass flow rate and to at least qualitatively determine, on the basis of the magnetic-field signal, whether an external magnetic field is established inside the measuring sensor.

摘要： The present disclosure relates to a transducer comprising a tube, a converter unit, an electromechanical exciter arrangement for stimulating and sustaining forced mechanical vibrations of the converter unit, and a sensor arrangement for detecting mechanical vibrations of the converter unit and for generating a vibration signal representing mechanical vibrations of the converter unit. The converter unit includes two connection elements connected to a displacer element and is inserted into the tube and connected thereto. The converter unit is configured as to be contacted by a fluid flowing through the tube and enabled to vibrate such that the connection elements and the displacer elements are proportionately elastically deformed. The transducer can be a constituent of a measuring system adapted to measure and/or monitor a flow parameter of the flowing fluid and further includes an electronic measuring and operating system coupled to the exciter arrangement and the sensor arrangement of the transducer.
