An assembly procedure for an electrode anchor, and a magnetic-induction flow meter, particularly for high pressure applications with medium pressures above 5.1 MPa (51 bar), having a measuring tube on which a multi-part electrode anchor for securing a measuring electrode is arranged. Included are: a) a coupling fitting, which is materially bonded to the measuring tube wherein the coupling fitting comprises a groove, or forms a groove together with the measuring tube; and b) a coupling insert for guiding and/or securing the measuring electrode the coupling insert being connected to the coupling fitting by way of a coupling. The coupling insert comprises anchoring wings which engage in the groove by a partial rotation and thereby effect the coupling.

1. A magnetic-induction flow meter especially for high pressure applications with medium pressures of more than 5.1 MPa (51 bar) with a measuring tube onto which an electrode anchor consisting of several parts for the purpose of fastening a measuring electrode is arranged, comprising the following components: a coupling fitting that is connected in same-substance manner with said measuring tube, with said coupling fitting having a groove or forming a groove together with said measuring tube; anda coupling insert to guide and/or fix said measuring electrode that is connected to said coupling fitting via a coupling, wherein:said coupling insert has anchoring wings that engage in said groove by means of a partial rotation and thus effect said coupling. 2. The magnetic-induction flow meter according to claim 1, wherein: said coupling insert has a recess running parallel to a measuring electrode axis, in which said measuring electrode and/or a measuring electrode attachment connected to it is arranged. 3. The magnetic-induction flow meter according to claim 1, wherein: one of: said measuring electrode and said measuring electrode attachment connected with said measuring electrode is connected by an insert against said coupling insert and is kept form-fitted as well as in a frictional connection in the process. 4. The magnetic-induction flow meter according to claim 1, wherein: the external diameter of said measuring tube has a flat surface in the area of said electrode anchor. 5. The magnetic-induction flow meter according to claim 3, wherein: said anchoring wings and said coupling fitting have surfaces placed on top of each other that have an inclination angle with regard to the flat surface of the external diameter of said measuring tube which is intended to determine the rotation direction of said coupling insert and said coupling fitting. 6. The magnetic-induction flow meter according to claim 1, wherein: said coupling fitting is welded to said measuring tube and preferably fastened with circumferential welding seams. 7. The magnetic-induction flow meter according to claim 1, wherein: said partial rotation of said coupling insert may be detached from said coupling fitting by partial rotation at an angle of 45-135°, preferably 60-120°, especially 80-100°. 8. The magnetic-induction flow meter according to claim 1, wherein: said coupling is marked by a form-fitted connection between said coupling insert and said coupling fitting. 9. The magnetic-induction flow meter according to claim 1, wherein: said coupling fitting is executed in the form of two L-shaped retaining brackets that reach behind said anchoring wings of said coupling insert. 10. The magnetic-induction flow meter according to claim 2, wherein: said recess of said coupling insert running parallel to said measuring electrode axis has a damping sleeve to limit the free movement of said measuring electrode and/or the measuring electrode attachment inside said recess and/or to electrically insulate said measuring electrode with regard to said coupling insert. 11. The magnetic-induction flow meter according to claim 3, wherein: said measuring electrode may in some sections be surrounded by saud insert made of a pressure-tight material arranged in a borehole in said measuring tube along the entire length of the borehole and having a sealing surface at the end, preferably as a projection on which said measuring electrode attachment is placed. 12. The magnetic-induction flow meter according to claim 11, wherein: said sealing surface has a material curvature pointing radially outwards. 13. The magnetic-induction flow meter according to claim 1, wherein: said measuring tube is at least partly covered inside with an electrically insulating material layer, with said measuring electrode punctuating this material layer and with the material layer having a material curvature in the direction of said measuring tube axis in the area of said measuring electrode. 14. An assembly process for an electrode anchor for a measuring electrode on a measuring tube of a magnetic-induction flow meter, comprising: a magnetic-induction flow meter especially for high pressure applications with medium pressures of more than 5.1 MPa (51 bar) with a measuring tube onto which an electrode anchor consisting of several parts for the purpose of fastening a measuring electrode is arranged, comprising the following components: a coupling fitting that is connected in same-substance manner with said measuring tube, with said coupling fitting having a groove or forming a groove together with said measuring tube; and a coupling insert to guide and/or fix said measuring electrode that is connected to said coupling fitting via a coupling, wherein: said coupling insert has anchoring wings that engage in said groove by means of a partial rotation and thus effect said coupling, the method comprising the following steps: a) if necessary, attachment of flat surfaces on the external diameter on the measuring tube of the magnetic-induction flow meter;b) fixing of a coupling fitting on the external diameter of the measuring tube, preferably while forming a groove together with the measuring tube;c) insertion of a coupling insert into the coupling fitting orthogonally to the measuring tube; andd) rotating movement of the coupling insert, with the anchoring wings arranged on the coupling insert engaging in the groove or a groove arranged in the coupling fitting, wherein:during the rotating movement a measuring electrode attachment partly arranged in the coupling insert, or a measuring electrode, is pressed against the coupling insert in a tight fit.
