  • Patent number: 11085802
    Abstract: The present disclosure relates to a method for operating a magnetic-inductive flow meter for measuring the flow rate or the volumetric flow of a medium in a measuring tube and to such a flow meter, wherein the medium is acted upon by magnetic fields of different polarity and field strength, wherein the alternation between magnetic fields causes a voltage pulse in the medium, wherein a voltage pulse during a phase without a magnetic field is used for calculation of a correction of an electrode voltage characteristic.

  • Patent number: 11047719
    Abstract: A magnetic-inductive flow meter and a method for operating such a magnetic-inductive flow meter for measuring the flow velocity or the volumetric flow rate of a medium in a measuring tube include subjecting the medium to magnetic fields of different polarity and field strength such that the changing between magnetic fields causes a voltage pulse in the medium and analyzing the voltage pulse to calculate a correction of an electrode voltage profile of a measuring electrode pair of the flow meter.

  • Patent number: 11029182
    Abstract: The present disclosure relates to a method for measuring flow velocity or volume flow of a medium using a magneto inductive flow measuring device and to an arrangement having a magneto inductive flow measuring device, as well as to a filling plant with an arrangement, wherein the medium has a low conductivity. A high accuracy of measurement is achieved by provision of a first narrowing of a medium-containing pipeline and/or a second narrowing of a medium-containing measuring tube, wherein the pipeline leads the medium to a measuring tube of the flow measuring device.

  • Patent number: 10473497
    Abstract: A magneto-inductive flow measuring device for ascertaining flow of a measured medium through a measuring tube having a measuring tube axis, comprising: at least a first coil component having a coil body for accommodating a coil core of a coil. The coil is wound on the coil body and the coil core is arranged in a first passageway of the coil body with a longitudinal axis of the coil core coaxial with the coil. At least two cable strands are arranged between the coil core and the coil body, wherein the cable strands serve for tapping the signal of two or more measuring electrodes arranged on the measuring tube. The cable strands extend within the coil component essentially along a cutting plane, which extends perpendicular to the measuring tube axis.

  • Publication number: 20140202257
    Abstract: An L-shaped sealing ring comprising two legs connected with one another to form an L-shape in cross section. A length of a first leg is part of a lateral surface of revolution about an axis of the L-shaped sealing ring. The first leg lies between the first length and the axis of revolution. A second leg is bounded toward the environment by a second length, wherein the first and second lengths are connected with one another via a connection contour. An intersection of first and second lines, forms a corner of a triangle, wherein the respective end points of the first and second lengths form other vertices of the triangle. The L-shaped sealing ring is so embodied that the surface area of the cross sectional area of the body of the L-shaped sealing ring in the triangle amounts to, at most, 60% of the areal content of the triangle, wherein the area of the L-shaped sealing ring in the triangle is non-concave.

  • Patent number: 8051722
    Abstract: An apparatus for measuring volume- or mass-flow of a medium in a pipeline. Included is a measuring tube, through which the medium flows in the direction of the longitudinal axis of the measuring tube; a magnet system, which is embodied in such a manner, that it produces a magnetic field passing through the measuring tube essentially transversely to the longitudinal axis of the measuring tube; at least one measuring electrode coupled with the medium, which is arranged in a bore in the wall of the measuring tube in a region lying essentially perpendicular to the magnetic field.

  • Patent number: 7650796
    Abstract: An apparatus for measuring and/or monitoring the flow of a medium to be measured, which is flowing through a measuring tube in the direction of the longitudinal axis of the measuring tube. The apparatus includes: A magnet arrangement which produces a magnetic field passing through the measuring tube and running essentially transversely to the longitudinal axis of the measuring tube; two measuring electrodes which are galvanically or capacitively coupled with the medium to be measured and which are arranged in such a manner that a measurement voltage is induced in them, evoked by the medium to be measured; an evaluation control unit, which, on the basis of the measurement voltage induced in the measurement electrodes, provides information concerning the volume flow of the medium to be measured in the measuring tube; wherein connecting lines, or signal lines, as the case may be, are provided, by way of which the measurement signals are led between the measurement electrodes and the control/evaluation unit.
