The device has a magnetic field generating device for generation of a magnetic field that is partially interfused at a measuring line (1). The measuring line has a variable cross section over the length, where the cross section in the middle area of the measuring line is smaller than at the ends of the measuring line. The measuring line has a rectangular or quadratic cross section at the middle area. Supports (5, 6) are connected with a housing (2) that has a circular cross section and holds the measuring line, where the supports are arranged within the middle area of the measuring line. |
