FIELD: instrumentation.SUBSTANCE: electrodeless electromagnetic flowmeter consists of a tube, three induction coils and a magnetic circuit. The induction coils are made in the form of flat multilayer printed boards, the magnetic circuit is a flat plate, and the coils and the magnetic circuit are located on the outer surface of the tube, forming three parallel layers, of which the first layer, located directly on the tube, is occupied by two coils which come into contact with each other with the ends of the boards on the line of the central perimeter of the tube, and the second and third layers are formed, respectively, by the third coil and the magnetic circuit, which are located symmetrically relative to the central tube perimeter.EFFECT: improving the accuracy of flow measurement and simplification of manufacturing flowmeter.2 cl, 3 dwg |
