摘要： The inventive in-line-measuring device comprises a vibratory-type measuring sensor provided with at least one measuring tube through which a measurable medium passes during the device operation. Said measuring tube is displaceable by means of an exciter arrangement at least temporarily and/or at least in a parallel direction according to lateral oscillations and at least temporarily and/or at least in a parallel direction according to torsion oscillations around the longitudinal imaginary axis of the measuring tube alternating with lateral oscillations or temporary superimposed therewith. In addition, the in-line-measuring device comprises a sensor arrangement for producing the measuring tube oscillations corresponding to representative oscillation measurements. An electronic unit of the measuring device, which controls the exciter arrangement, generates, by means of the oscillation measuring signal an/or an excitation current at least temporary at least one measuring value representing at least one measurable physical measuring quantity, par example mass flow rate-mass flow rate, a medium density or viscosity. Said electronic unit of the measuring device also makes it possible to determine a first intermediate value which corresponds to the lateral current fraction of the excitation current for maintaining the lateral oscillations of the measuring tube and a second intermediate value corresponding to the torsion current value of the excitation current for maintaining the torsion oscillations of the measuring tube and/or to a torsion oscillation damping of the measuring tube. A high-accuracy value is determined taking into account said two intermediate values and is valid event for two- or more-phased media.

摘要： The invention relates to a Coriolis mass flowmeter comprising a vibration-type measuring sensor (1) comprising at least one measuring tube (10) through which a medium can flow during operation. During operation, the measuring tube moves by mechanical vibrations, especially bending vibrations, by means of an exciter arrangement (40). The Coriolis mass flowmeter also comprises a sensor arrangement (50) for generating vibration measuring signals (sl, s2) representing inlet-side and outlet-side vibrations of the measuring tube (10). Flowmeter electronics (2) controlling the exciter arrangement generate an intermediate value (X'm) which is derived from the vibration measuring signals (s1, s2) and represents an uncorrected mass flow, and an exciter current (iexc) driving the exciter arrangement. An intermediate value (X2) is derived from the exciter current and/or from part of the exciter current (iexc), said value corresponding to a dampening of the vibrations of the measuring tube (11), dependent on an apparent viscosity and/or a viscosity-density product of the medium guided in the measuring tube (11). Furthermore, a correction value (XK) for the intermediate value (X'm) is generated using the intermediate value (X2) and a viscosity measuring value (Xeta) that is determined previously or during operation and corresponds to a viscosity of the medium guided in the measuring tube and/or a pre-determined reference viscosity. On the basis of the intermediate value (X'm) and the correction value (XK), the flowmeter electronics can then generate an accurate mass flow measuring value (Xm).

摘要： The inline measuring device comprises a vibratory-type transducer and a measuring device electronics electrically coupled with the vibratory-type transducer. The vibratory-type transducer includes at least one measuring tube being inserted into the course of a pipeline and serving for conducting a mixture to be measured. An exciter arrangement acting on the measuring tube for causing the at least one measuring tube to vibrate and a sensor arrangement sensing vibrations of the at least one measuring tube and delivering at least one oscillation measurement signal representing oscillations of the measuring tube. The measuring device electronics delivers an excitation current driving the exciter arrangement. Further, the inline measuring device electronics is adapted to produce a measured value representing the physical, measured quantity of the mixture to be measured. Therefor, the measuring device electronics estimates from the excitation current and from said at least one oscillation measurement signal a Coriolis coupling coefficient. This Coriolis coupling coefficient corresponds with an instantaneous coupling between a first natural eigenmode of the measuring tube currently driven by the exciter arrangement and a second natural eigenmode of said measurement tube. In this second eigenmode the measurement tube has an eigenform corresponding with a mode of vibration caused by Coriolis forces induced in the flowing mixture. Due to a variation of a concentration of at least one of a component of the mixture the Coriolis coupling coefficient varies in time.

摘要： The invention relates to a method for the anticipatory maintenance of a magnetic-inductive flow meter and/or to a method for determining the electric conductivity of a medium flowing through a magnetic-inductive flow meter, the magnetic-inductive flow meter comprising the following components: a magnet system, which produces a magnetic field permeating the measuring tube and extending substantially transversely to the measuring tube axis, at least two measuring electrodes coupled to the medium, the electrodes having a defined resting potential and being disposed in a region of the measuring tube that is located substantially perpendicular to the magnetic field, and a control/evaluation unit, which supplies information about the volume or mass flow of the medium in the measuring tube based on the measuring voltage induced in the measuring electrodes. For example, a first excitation signal having a first frequency (f 1 )
