PURPOSE:To shorten the length of a measuring tube by making the length in the tubular axis direction of the tip face of a magnetic pole shorter than the length in the tubular axis direction of the magnetic pole in an exciting coil part. CONSTITUTION:The titled detector consists of a measuring tube 1 in which insulating lining is applied to the inside surface, a magnetic field generating part having exciting coils 5a, 5b and magnetic poles 4a, 4b for generating a magnetic field in the diameter direction of the measuring tube 1, electrodes 3a, 3b which are positioned on one straight line being orthogonal to the magnetic field direction and the flow velocity direction, respectively, and an external cylinder 7 for fixing the whole. Also, the length in the tubular axis direction of the tip face of the magnetic poles 4a, 4b is made shorter than the length in the tubular axis direction of the magnetic poles 4a, 4b in the exciting coil part, and the range in the tubular axis direction centering around the electrode position of the generated magnetic field is narrowed.
