摘要： A method for manufacturing an apparatus for measuring flow of a fluid flowing through a measuring tube of metal using the magneto-inductive principle, comprising the method steps as follows: securing first and second collars of metal externally on the measuring tube with an orientation perpendicular to the tube axis of the measuring tube; lining the measuring tube internally with an electrically non-conductive, elastic liner; and altering a measuring section of the measuring tube located at least partially between the first collar and the second collar by means of cold deformation in such a manner that the cross sectional area of the measuring section is reduced compared with the cross sectional area of an inflow section of the measuring tube located upstream from the measuring section and an outflow section of the measuring tube located downstream from the measuring section.

摘要： 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.
