MAGNETIC-INDUCTIVE FLOW RATE MEASURING DEVICE, MAGNETIC CIRCUIT DEVICE AND METHOD FOR PRODUCING SAME

A magnetically-inductive flow-measuring device, with a measuring tube for guiding an electrically-conductive medium, with a coil for generating a magnetic field that at least partially runs through the measuring tube and with a magnetic circuit device for guiding the magnetic field outside of the measuring tube, the magnetic circuit device has at least one coil core, a first yoke element, a second yoke element, a first pole piece and a second pole piece, the coil core is arranged inside the coil and the measuring tube is arranged between the first pole piece and the second pole piece. To provide a magnetically-inductive flow-measuring device with a magnetic circuit device, the magnetic circuit device is made from an at least partially bent sheet element or from multiple at least partially bent sheet elements.
