Title:
MAGNETIC AUTOMATION FLOW RECORDER
Document Type and Number:
WIPO Patent Application WO/2016/124131
Kind Code:
A1
Abstract:
A magnetic automation flow recorder, comprising a plurality of coaxially arranged hard magnetic rotating wheels (1), the hard magnetic rotating wheels (1) being circular and being provided with a preset rotation ratio, each hard magnetic rotating wheel (1) corresponding to at least one biaxial magnetoresistance angle sensor (2; 2(1)), the biaxial magnetoresistance angle sensor (2; 2(1)) measuring the angular position of the hard magnetic rotating wheel (1) within the range of 0-360 degrees, the biaxial magnetoresistance angle sensor (2; 2(1)) including at least two uniaxial linear magnetoresistance sensors, the uniaxial linear magnetoresistance sensors being X-axis magnetoresistance sensors or Z-axis magnetoresistance sensors, the X-axis magnetoresistance sensors measuring a magnetic field component along the tangential direction of the circumference of the hard magnetic rotating wheel (1) at the position where the hard magnetic rotating wheel (1) is located, the Z-axis magnetoresistance sensors measuring a magnetic field component along the radial direction of the hard magnetic rotating wheel (1) at the position where the hard magnetic rotating wheel (1) is located. With respect to electronic water meters having X and Y biaxial angle sensors, the present flow recorder has the advantages that the mounting position is flexible, the influence of neighbouring hard magnetic rotating wheels (1) is slight, and power consumption is low.
