  • Publication number: 20190162702
    Abstract: 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 R? and a mode dependent mutual induction reactance Rg3 which depends on the position of the exciter.

  • Publication number: 20170356833
    Abstract: A method is provided for measuring density of a fluid by means of at least one at least sectionally curved measuring tube. The measuring tube is adapted to be flowed through by the fluid and concurrently to be caused to vibrate over a wanted oscillatory length, namely a tube length measured from a first tube end to a second tube end, a length which is greater than a minimum separation of the second tube end from the first tube end. According to the invention, among other things, also a tilt measured value representing an inclination of the at least one measuring tube in the static resting position relative to a local acceleration of gravity is ascertained, in such a manner that such represents an angle of intersection between a direction vector of an imaginary first reference axis (y-axis) and a direction vector of an imaginary second reference axis (g-axis).

  • Patent number: 8281667
    Abstract: In a method for determining mass flow with a Coriolis mass flow measuring device arranged on a rotary filler, a correction value ?{dot over (m)} is ascertained, which is proportional to the RPM n of the rotary filler. This correction value is subtracted from the conventionally ascertained value {dot over (m)} of the mass flow. The corrected measured value {dot over (m)}corr is thus {dot over (m)}corr={dot over (m)}??{dot over (m)}.
