Document Type and Number:
Japanese Patent JP2923854
Kind Code:
B2
Abstract:
A magnetoinductive flow meter with a measuring tube, an electromagnet device with at least one electric conductor loop arrangement for generating a magnetic field penetrating the measuring tube at right angles to the longitudinal axis thereof, and at least two measuring electrodes, which are arranged opposite one another at right angles to the longitudinal axis of the measuring tube in such a way that they can be used to tap a measuring voltage induced owing to the flow, proceeding at right angles to the magnetic field, of a liquid flowing through the measuring tube. The electric conductor loop arrangement has an electrically conductive sheet-metal part which is fitted on the inner side or on the outer side of the body of the measuring tube and is provided with at least one cutout as inner boundary of the conductor loop current path running around the cutout in the sheet-metal material. The flow meter has a simpler design of the electromagnet device and permits square-wave magnetic field excitation by means of a comparatively high frequency even in the case of measuring tubes having large nominal diameters (for example DN>300) since the conductor loop arrangement has a low inductance.
