Abstract
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.
