Abstract
A flow meter includes a rotating structure, a sensing element and a processing circuit. The rotating structure has a shaft, a rotating element, and a magnetic element. The rotating element can be driven by a fluid in a pipeline to rotate around the shaft. The magnetic element is arranged on the rotating element with two magnetic poles parallel to a tangent line of rotating circle of the rotating element. The sensing element is separated from the rotating structure by a distance, and includes a first sensing unit and a second sensing unit, respectively sensing a magnetic field of the magnetic element in different directions to generate a first component signal and a second magnetic field component signal. The processing circuit is connected to the sensing element, and generates an angle of the rotating structure according to the first magnetic field component signal and the second magnetic field component signal.
