Abstract:
    The invention relates to an amorphous alloy flow sensor that comprises the liner and its upper cap, the sensing probe, the casing, the fore liquidguide mount, the after liquidguide mount, the rotor, the bearing. The sensing probe is sealed in the liner and its upper cap which are fixed on the upper of the casing; the casing is a circle hollow canal on which the fore liquidguide mount and the after liquidguide mount are mounted, the depression which is used to fix the bearing of the rotor is set at the fore liquidguide mount and the after liquidguide mount; said sensing probe consists of the coil, the amorphous iron core, the permanent magnet, the coil circles the outer circumference of the amorphous iron core in mode of helical, the permanent magnet is mounted above the amorphous iron core and the coil. The invention could test the weak signal sensitively, but also the signal waveform is relatively stable and simple, so it is convenient to process the signal, and the signal is displayed in digit or connected with the microcomputer with the designed circuit to control the flow measured directly.
