Abstract
A magnetic-inductive flowmeter includes a measuring tube for guiding an electrically conductive medium, a magnetic field device, a magnetic field guiding device, and a control and evaluation unit. The magnetic field device includes at least three coils for generating a magnetic field through the measuring tube. The magnetic field guiding device guides the magnetic field with at least three measuring electrodes for tapping a measurement voltage induced in the medium. The control and evaluation unit generates the magnetic field by energizing the coils and evaluates the measurement voltage. The coils are distributed over a circumference of the magnetic field guiding device, which acts a coil core in a region of the coils, so that the coils are arranged with their coil longitudinal axes in the circumferential direction with respect to the measuring tube. Each of the measuring electrodes is arranged between two coils in the radial direction.
