Abstract
An electromagnetic flow sensor for a fluid flowing through a pipe comprises a measuring tube which can be inserted into a pipe. The measuring tube comprises a support tube as an outer covering of the measuring tube, a tubular liner of insulating material, located in a lumen of the support tube, for conducting the flowing fluid isolated from the support tube, and an open-pore reinforcing body for stabilizing the liner. The reinforcing body is sintered directly in said support tube. A magnetic-circuit arrangement is disposed on the measuring tube for producing and guiding a magnetic field which induces an electric field in the flowing fluid. Electrodes pick up voltages from the electric field. Furthermore, the reinforcing body has coil-core seats for coil cores of the magnetic-circuit arrangement.
