20100089171 | APPARATUS FOR MEASURING VOLUME-OR MASS-FLOW OF A MEDUIM IN A PIPELINE - 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. The measuring electrode has an elongated electrode shaft having a first widened end region, which is so dimensioned, that its diameter larger is than the diameter of the bore in the wall of the measuring tube, in which the measuring electrode is placed; and a control/evaluation unit, which, on the basis of a measurement voltage induced in the at least one measuring electrode, delivers information concerning volume- or mass-flow of the medium in the measuring tube. In the opposing, second, end region of the electrode shaft of the measuring electrode, at least one radial recess or at least one radial protrusion is arranged. Furthermore, a binding-element is provided, which is so embodied, that it fixes the measuring electrode in the bore of the measuring tube in the axial direction by engaging with the at least one radial recess or protrusion. | 04-15-2010 |
20100147085 | Pipeline or Measuring Tube Having at Least One Layer Which Insulates at Least in Certain Regions, and Process for the Production Thereof - A pipeline or measuring tube having at least one insulating layer, at least in certain regions, and comprising, manufactured in a primary shaping method, a tubular element, which has an otherwise closed structure and which has at least one region with an open-pored, cellular structure, wherein the material of the insulating layer, in the applying of the insulating layer, can penetrate into the pores of the open-pored, cellular structure of the tubular element and the insulating layer has on the side to be insulated a closed, homogeneous structure. | 06-17-2010 |
20120096937 | Flow measuring device and method for manufacture of a measuring tube of a flow measuring device - A method for the manufacture of a measuring tube of a flow measuring device, and to a flow measuring device. The measuring tube has a lumen for accommodating a flowing, measured material. The method comprises: introducing at least one, essentially cylindrical, hollow body into a support tube; joining the essentially cylindrical, hollow body to the support tube by mechanically deforming at least one portion of the essentially cylindrical, hollow body; and embedding the hollow body joined to the support tube in an electrically and/or chemically insulating, isolating material; wherein the lumen of the measuring tube is formed by the electrically and/or chemically insulating, isolating material. | 04-26-2012 |
20120297891 | MAGNETO-INDUCTIVE, FLOW MEASURING DEVICE - A magneto-inductive, flow measuring device for measuring flow of a measured medium through a measuring tube, comprising: at least a first coil assembly for accommodating a coil core is arranged in a first passageway. The coil core has a broadened part and a first stop, which is arranged between the measuring tube and the coil. The broadened part of the coil core in the assembled state of the first coil assembly lies against the first stop of the coil body and prevents shifting of the coil core relative to the coil body along the longitudinal axis of the coil core in a first direction facing away from the measuring tube. The coil body has a second stop, wherein the coil core is secured to the coil body with a securement element (which, in the assembled state, lies against the second stop of the coil body under a prestress along the longitudinal axis of the coil core between the first stop and the second stop of the coil body. | 11-29-2012 |
20140150567 | Magneto Inductive, Flow Measuring Device - A magneto inductive flow measuring device having a measuring tube and at least one magnet system arranged on the measuring tube, wherein the measuring tube has at least one planar area and an otherwise cylindrical lateral surface, which border the measuring tube from its environment, against which planar area the magnet system is prestressed The magnet system is prestressed against the planar area of the measuring tube by means of a screwed connection between measuring tube and magnet system and/or the magnet system is prestressed against the planar area of the measuring tube by means of a mounting clip, which is secured shape-interlocked to the measuring tube. A method for manufacturing the magneto inductive, flow measuring device is also discussed. | 06-05-2014 |
20140157910 | Magneto Inductive, Flow Measuring Device - A magneto inductive, flow measuring device including a measuring tube and, arranged on the measuring tube, at least one magnet system, which includes a pole shoe. The measuring tube has at least one planar area and an otherwise cylindrical lateral surface, which border the measuring tube from its environment. The pole shoe is so formed relative to the measuring tube that it contacts the planar area of the measuring tube and has a predetermined minimum separation for the otherwise cylindrical lateral surface of the measuring tube. The pole shoe surrounds the measuring tube with a circular arc angle of at least 10°. | 06-12-2014 |
20140202257 | L-Shaped Sealing Ring - 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. | 07-24-2014 |
