摘要:
An inline measuring device includes a vibration-type measurement pickup having at least one measuring tube, which has a medium to be measured flowing through it during operation. The measuring tube is made by means of an exciter arrangement to execute, at least at times and/or at least in part, lateral oscillations and, at least at times and/or at least in part, torsional oscillations about an imaginary measuring tube longitudinal axis. The torsional oscillations alternate with the lateral oscillations or are, at times, superimposed thereon. Also included is a sensor arrangement for producing oscillation measurement signals correspondingly representing oscillations of the measuring tube. Measuring device electronics controlling the exciter arrangement generates, by means of at least one of the oscillation measurement signals and/or by means of the exciter current, at least at times, at least one measured value, which represents the at least one physical quantity to be measured. Additionally, the measuring device electronics also determines a first intermediate value, which corresponds to the lateral current component of the exciter current serving to maintain the lateral oscillations of the measuring tube and/or to a damping of the lateral oscillations of the measuring tube, as well as a second intermediate value, which corresponds to a torsional current component of the exciter current serving to maintain the torsional oscillations of the measuring tube and/or to a damping of the torsional oscillations of the measuring tube. With the goal of producing the measured value at high accuracy, such value is determined also taking into consideration these two intermediate values. The measured value obtained in this way is distinguished especially by high accuracy also in the case of media of two, or more, phases.

An inline measuring device which serves for measuring at least one physical, measured variable of a medium conveyed in a pipeline, includes a measurement pickup of vibration-type, as well as a measuring device electronics electrically coupled with the measurement pickup. The measurement pickup includes at least one, essentially straight measuring tube serving to convey the medium to be measured and communicating with the connected pipeline, an exciter mechanism acting on the measuring tube for causing the at least one measuring tube to vibrate, during operation, at least at times and/or at least in part, with torsional oscillations about a torsional oscillation axis imaginarily connecting an inlet end of the measuring tube and an outlet end of the measuring tube, as well as a sensor arrangement for registering 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, at least at times, an exciter signal driving the exciter mechanism and generates, by means of the at least one oscillation measurement signal and/or by means of the exciter signal, at least at times, at least one measured value, which represents at least one physical, measured variable of the medium to be measured. Moreover, the measuring device electronics determines, on the basis of the at least one oscillation measurement signal and/or on the basis of the exciter signal, repetitively, an oscillation frequency of the torsional oscillations of the measuring tube and the measuring device electronics monitors, based on the oscillation frequency of the torsional oscillations, at least one operating condition of the at least one measuring tube. Additionally provided is an inline measuring device of the described kind used for monitoring an operating condition of a tube wall, especially also a section of the attached pipeline.

A vibration meter and a method of measuring a viscosity of a fluid flowing through a pipe are disclosed. The vibration meter comprises meter electronics and a transducer assembly with an electromechanical excitation arrangement and with a flow tube which oscillates in operation. A sensor arrangement produces sensor signals representative of inlet-side and outlet-side deflections of the flow tube. An evaluation circuit derives from said sensor signals and from an excitation current generated by an excitation circuit for the excitation arrangement a viscosity value representative of the viscosity of the fluid.

The measuring transducer includes: a measuring tube vibrating, at least at times, during operation and serving for conveying a medium, wherein the measuring tube communicates with a pipeline via an inlet tube piece at an inlet end and an outlet tube piece at an outlet end; a counteroscillator, which is affixed to the measuring tube on the inlet end to form a first coupling zone and affixed to the measuring tube on the outlet end to form a second coupling zone; a sensor arrangement secured, at least in part, to the counteroscillator for registering oscillations at least of the measuring tube; an exciter mechanism secured, at least in part, to the counteroscillator for driving at least the measuring tube; a transducer housing affixed to the inlet tube piece and the outlet tube piece; and connection lines, especially connection lines for the exciter mechanism and/or for the sensor arrangement, of which connection lines at least one is secured at least sectionally along the counteroscillator and secured at least pointwise thereto, as well as to the transducer housing. The connection lines are routed essentially symmetrically with respect to a principal axis of inertia of the inner part formed by means of measuring tube and counteroscillator, especially mirror-symmetrically with respect to at least one principal axis of inertia of the counteroscillator, whereby an essentially symmetrical damping force per unit length can be assured in the measuring transducer.

A sealable folding box in the shape of a parallelepiped or cube with attached bottom and cover flaps and an attachment flap—is provided with an attachment recess—is that is arranged on an edge of the folding box body that extends between these flaps. To this end, the folding-box body—seen in the lengthwise direction of the matrix—has a sealing flap on one end and a combination section on the other end. The combination section consists of an inside area and at least one outside area, whereby the inside area is an attachment flap—provided with an attachment recess—while the outside area is used to attach the combination section to the side wall with which it is in contact. With the invention, a folding box is provided that can be handled simply and reliably in production, storage and filling, that encloses the contents largely dust-tight and that can be marketed stacked or suspended.
