  • Method of making a sensor for a magnetic inductive flowmeter
    Patent number: 4716649
    Abstract: A measured-value sensor for an inductive flowmeter comprises a fluid impermeable sintered ceramic measuring tube adapted to be positioned in a conductive-liquid flow path. Magnetic coils surround the tube and are adapted to apply a magnetic field to a conductive liquid traversing the path. A pair of diametrically opposite measuring electrodes contact the liquid traversing the path for tapping an induced voltage across the electrodes representing the flow of the liquid along the path, each of the electrodes having a metallic shaft traversing the tube substantially radially and sealingly sintered to the material of the tube. The ends of the ceramic measuring tube are provided with a flange, ground at its peripheral wall surface and fastened by shrinkage stress in a bore of a steel casing.
    Type: Grant
    Filed: March 19, 1984
    Date of Patent: January 5, 1988
    Assignee: Rheometron AG
    Inventors: Franz Bittner, Boudewijn J. Poortman, Kristian Rademacher-Dubbick, Abram K. Roskam, Udo Stevens, Wouter T. Tromp, Walter Beisler, Siegfried Bock, Hermann Bertsch
