Magnetically inductive flowmeter

A magnetically inductive flowmeter for measuring flow velocity, or volume flow, of a medium flowing through a measuring tube, the magnetically inductive flowmeter comprising:

• a measuring tube having a measuring tube axis;
• a magnet system including a first coil system including a first coil and a first coil core arranged within the first coil, wherein the magnet system is adapted to produce a magnetic field perpendicular to the measuring tube axis;
• at least two measuring electrodes for sensing a flow dependent electrical voltage induced in the medium by the magnetic field, wherein the at least two measuring electrodes are arranged in or on the measuring tube and are adapted to sense the voltage capacitively or galvanically;
• an electronic measuring/operating circuit for operating the magnet system and the at least two measuring electrodes;
• and
• a field guide adapted to guide the magnetic field between a side of the first coil far from the measuring tube and a side of the measuring tube far from the first coil,
• wherein the magnet system further includes a first pole shoe adapted to lead the magnetic field between the measuring tube and the field guide,
• wherein the first pole shoe includes a first folded sheet metal piece and the field guide includes a first folded sheet metal piece,
• wherein the first pole shoe and the field guide are magnetically and mechanically in contact at least in an interior of the first coil, and
• wherein the first pole shoe and the field guide at least partially form the first coil core in the interior of the first coil.
