  • Publication number: 20220381593
    Abstract: A measuring tube includes a support tube having a metal wall surrounding a lumen, a thermoplastic liner lining the support tube and a sensor element. The liner tube has an outer diameter less than an inner diameter of the support tube, and the wall of the liner tube has a fold, such that both the lumen and a lateral surface of the liner tube have a form deviating from that of a circular cylinder. The lateral surface is curved concavely. The liner tube is positioned in the lumen and heated into a viscoelastic state and deformed such that the wall of the liner tube unfolds and presses against the wall of the support tube, such that the lateral surface is curved convexly. The liner tube is cooled and a shape is formed between the liner tube and support tube for durably securing the liner tube in the support tube.

  • Publication number: 20190277679
    Abstract: The present disclosure relates to a method for operating a magnetic-inductive flow meter. The method includes steps of generating a magnetic field in a medium during a feeding phase, wherein the feeding phase has a shot phase and a measuring phase, and measuring a coil current. The method also includes switching over from the shot phase to the measuring phase as soon as the coil current reaches a limit value, recording a time period from the beginning of the feeding phase to reaching the limit value, and determining a deviation of the time period from a target time period. The method further includes generating the magnetic field during a subsequent feeding phase, where a shot voltage of the subsequent feeding phase is adapted in dependence on the deviation in order to reduce the deviation of the time period from the target time period of the next feeding phase.
