The measuring tube is for an electromagnetic flow meter and has a tube member made of a non-magnetic material that is provided with opposite through passages that have electrodes extended therethrough. An insulating lining of an enamel priming layer coats the inner surface of the tube member and fills the gaps between the electrodes and the tube member surfaces defining the through passages, the lining also including an covering enamel layer covering the priming layer surface that is within the tube member interior. The end faces of the electrodes that are in the tube member interior have the enamel material cleared therefrom. The priming layer may be formed by filling the tube member with a priming enamel slip, pouring out the slip material, cleaning the electrode end surfaces that are within the tube member interior and then heating to melt the slip material and then cooling. The covering layer may be formed by the same steps.

Method of making a measuring tube for an electromagnetic flow meter, and

The invention relates to an electromagnetic flow meter of the type having a cylindrically shaped tube section with two magnetic poles each having a core section carrying a winding attached to the outside and on opposite sides of the tube section. Smaller dimensions and lower losses in the magnetic circuit are achieved by providing a casing or yoke unit formed of sheet metal members and having U-shaped core sections. The core sections have central webs adapted to the curvature of the pole shoes and rectangular coils are disposed respectively between the associated pole shoes and sheet metal yoke members.

Electromagnetic flow meter

The invention relates to an electromagnetic flow meter with a magnetic system having two magnetic poles which are attachable to a measuring tube from the outside, an outer yoke, and at least one separating gap. Each pole has a pole shoe and a core section carrying a winding which is connected at the radially outward end thereof without a gap to the adjoining magnetic system portion and the separating gap is disposed beyond the magnetic path for the stray flux.
