Patent number: 7221156
Abstract: The invention relates to a magnetic flow sensor (1, 21, 51) comprising a) a loop-shaped magnetic field conductor comprising a point (2, 22, 32, 52) which expands to form a bar or a film (3, 23, 52), a loop-shaped part (3a, 23a, 53a) and at least one part (4, 24, 54?, 54?) which guides back the magnetic field lines of the probe, b) SQUID (7, 27, 57), c) and a diaphragm (5, 25, 35, 55) comprising a hole (6, 26, 36, 56), whereby the part (4, 24, 54?, 54?) which guides the magnetic field lines of the probe back to the loop-shaped magnetic field conductor is connected to the diaphragm (5, 25, 35, 55).
