Abstract: A measuring transducer includes: a transducer module including a housing and a coil within and connected with the housing; and, set in the transducer module, a transducer module including a tube and a magnet secured on a middle segment of the tube. The tube wall is so formed that a directrix of a channel surface of the middle segment extends outside a first reference plane of the measuring transducer defined by first and fourth reference axes, and the magnet is secured on the middle segment such that a second reference plane of the measuring transducer defined by second and fourth reference axes is parallel to a third reference plane defined by third and fifth reference axes or that the second and third reference planes intersect one another to form an angle of intersection of no more than 1°.

Abstract: A measuring system includes a measuring and operation electronic unit (ME) and a transducer device electrically coupled thereto. The transducer device (MW) has at least one tube, through which fluid flows during operation and which is caused to vibrate meanwhile, a vibration exciter, two vibration sensors for generating vibration signals, and two temperature sensors for generating temperature measurement signals (θ1, θ2). The temperature sensors are coupled to a wall of the tube in a thermally conductive manner. The ME is designed to feed electrical power into the at least one vibration exciter to cause mechanical vibrations of the tube by an electrical excitation signal. The ME generates a mass flow sequence representing the instantaneous mass flow rate (m) of the fluid, so that, at least for a reference mass flow rate, the mass flow measurement values are independent of the temperature difference.

Abstract: A Coriolis mass flow measuring device and/or density measuring device includes two bent measuring tubes, which extend mirror symmetrically to a first mirror plane between the measuring tubes, an actuator arrangement and at least one sensor arrangement. At the inlet end and at the outlet end, a collector, with which the measuring tubes are joined, wherein the collectors each fulfill the functionality of a node plate. A support body, which connects the collectors rigidly with one another; and inlet end and outlet end, in each case, at least one plate-shaped coupler, which connect the measuring tubes pairwise with one another, in order to form an oscillator. The couplers have tube openings for measuring tubes, wherein the measuring tubes are connected at least sectionally with the couplers, wherein inlet end and outlet end, in each case, at least one coupler has, between the measuring tubes, a tuning opening for influencing the oscillation characteristics of the oscillator.

Abstract: The Coriolis mass flowmeter comprises a measuring transducer having a vibration element, an exciter arrangement, and a sensor arrangement The flowmeter further includes an electronic transmitter circuit coupled with the exciter arrangement and the sensor arrangement. The transmitter circuit supplies power to the exciter arrangement to force mechanical oscillations having a wanted frequency. The sensor arrangement includes two electrodynamic oscillation sensors to convert oscillatory movements of the vibration element into an electrical signal having an alternating voltage having an amplitude dependent on the wanted frequency and on a magnetic flux of its oscillation sensor. The sensor arrangement includes a magnetic field detector adapted to convert changes of the magnetic field into a magnetic field signal having an amplitude dependent on a magnetic flux and/or an areal density of the magnetic flux. The transmitter circuit ascertains mass flow measured values and ascertains whether an external magnetic field is present.
