DEVICE FROM MEASUREMENT AND/OR MONITORING OF THE THROUGHFLOW OF A MEDIUM FOR MEASUREMENT

摘要

According to the invention, the measuring accuracy of a magnetic inductive throughflow measuring device may be increased, whereby the electrode cables (5, 6) or the electrode lines are run essentially symmetrical to a part region of the measuring tube (2) and to both pole shoes (12). A first part region (20) is defined in which both electrode cables (5, 6) or both electrode lines run in the outer region of the measuring tube (2) and the pole shoe (12), a third part region (21) is defined, in which both electrode cables (5, 6) or electrode lines run parallel to each other and a second part region (22) is provided between the first part region (20) and the third part region (21), in which both electrode cables (5, 6) or electrode lines are arranged such that a critical surface (14) is defined between the same, running essentially perpendicular to the main direction of the magnetic field of the magnet arrangement and the electrode cables (5, 6) or electrode lines, in the region of said defined surface (14), are arranged and/or wired such that interference voltages, induced in the electrode cables (5, 6) or electrode lines, are at least approximately compensated for.
