In an electromagnetic flow meter having a ceramic measuring tube, a housing arrangement is provided which forms a fluid tight capsule surrounding the measuring tube to prevent the escape of fluid if the tube should happen to crack or break in the use thereof.

Electromagnetic flow meter

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.

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.

An electromagnetic flow meter having a magnet system with pole shoes on opposite sides of a measuring tube, a magnetic coil arrangement with a yoke for the magnetic return circuit, and two measuring electrodes between the respective pole shoes. The magnetic coil is coaxial with the measuring tube and surrounds the pole shoes and the pole shoes are connected to the yoke by radially extending webs at opposite ends of the magnetic coil.
