Magneto Inductive, Flow Measuring Device

A magneto inductive flow measuring device, comprising:

• a measuring tube;
• and
• at least one magnet system arranged on said measuring tube, wherein:
• said measuring tube has at least one planar area and an otherwise cylindrical lateral surface, which border said measuring tube from its environment, against which planar area said magnet system is prestressed;
• said magnet system is prestressed against said planar area of said measuring tube by means of a screwed connection between said measuring tube and said magnet system and/or said magnet system is prestressed against said planar area of said measuring tube by means of a mounting clip, which is secured shape-interlocked to said measuring tube.

The magneto inductive flow measuring device as claimed in claim 12, wherein:

• said magnet system includes a coil and a pole shoe;
• said coil includes a coil core;
• said pole shoe is prestressed with a predetermined force against the planar area of said measuring tube;
• and
• said coil core is prestressed with the same predetermined force against said pole shoe.

A method for manufacturing a magneto inductive, flow measuring device, comprising:

• a measuring tube;
• and at least one magnet system arranged on said measuring tube, wherein:
• said measuring tube has at least one planar area and an otherwise cylindrical lateral surface, which border said measuring tube from its environment, against which planar area said magnet system is prestressed;
• said magnet system is prestressed against said planar area of said measuring tube by means of a screwed connection between said measuring tube and said magnet system and/or said magnet system is prestressed against said planar area of said measuring tube by means of a mounting clip, which is secured shape-interlocked to said measuring tube, comprising the steps of:
• providing a measuring tube having a circularly cylindrical shaped lateral surface is provided with a planar area, against which a magnet system is prestressed;
• prestressing the magnet system against the planar area of the measuring tube by means of a screwed connection between measuring tube and magnet system;
• and/or
• prestressing the magnet system against the planar area of the measuring tube by means of a mounting clip, which is secured shape-interlocked to the measuring tube.
