Abstract
A method of manufacturing an electromagnetic flow sensor having a measuring tube with an insulating liner having a reinforcing body embedded therein includes the steps of producing the liner in situ in a support tube, and forming a sintering space in the support tube by inserting a sintering mandrel therein. The support tube is closed, leaving one filling aperture for a granular material to be sintered. The reinforcing body is formed in the support tube such that it fits its lumen, by introducing the material to be sintered into the sintering space, sintering, and removing the mandrel. A casting space is formed in the support tube by fixing a casting mandrel therein, and leaving one casting aperture for a liquefied insulting material. The liner is formed by introducing the insulating material into the casting space, allowing to penetrate into the reinforcing body, and solidify in the support tube lumen.
