摘要： A magnetoinductive flowmeter incorporates an electromagnetic circuit with at least one coil and a minimum of two detachably interconnected components of a magnetic material. One of the components features a resiliently deformable spring section that presses against the other component. The result is an easy-to-assemble magnetoinductive flowmeter that can be manufactured with substantial production tolerances.

摘要： A magnetoinductive flowmeter and a method for operating same utilizing a measuring tube through which flows an electrically conductive medium, as well as two measuring electrodes and a magnet with two field coils positioned parallel to each other on mutually opposite sides of the measuring tube. The measuring electrodes are so positioned that their connecting line extends along an essentially perpendicular vector relative to the direction of flow and to the magnetic field as well as through the cross-sectional center of the measuring tube. For normal flow-measuring operation, the two field coils are so energized that an essentially homogeneous magnetic field is generated, permeating the medium flowing through the measuring tube, while for determining the flow rate the voltage present between the two measuring electrodes is collected at one or both measuring electrodes and measured against a reference potential. The normal flow-measuring operation is intermittently interrupted and the two field coils are energized in a manner as to generate an inhomogeneous magnetic field that permeates the medium flowing through the measuring tube, and the voltage present between the two measuring electrodes is collected. This permits a diagnosis of the flowmeter.
