摘要： An automatic magnetic flow recording device, comprises a multitude of coaxially disposed hard magnetic rotating wheels wherein the hard magnetic rotating wheels are circular, and rotate with respect to each other by a predetermined transmission ratio. Each hard magnetic rotating wheel has at least one corresponding biaxial magnetoresistive angle sensor. The biaxial magnetoresistive angle sensors measure the angular positions of the hard magnetic rotating wheels within the range of 0-360 degrees. The biaxial magnetoresistive angle sensors comprise two single-axis linear magnetoresistive sensors, wherein the single-axis linear magnetoresistive sensors are an X-axis magnetoresistive sensor or a Z-axis magnetoresistive sensor. The X-axis magnetoresistive sensor of the hard magnetic rotating wheel measures a magnetic field component parallel to the tangent of the circumference of the hard magnetic rotating wheel. The Z-axis magnetoresistive sensor of the hard magnetic rotating wheel measures a magnetic field component along the radial direction of the hard magnetic rotating wheel. This flow meter recording device has several advantages compared to electronic flow meters with X, Y biaxial angle sensor. These include flexibility of the mounting position, small adjacent hard magnetic rotating wheel interference, and low power consumption.

摘要： The present invention discloses a direct read metering device, comprising a digital counting wheel connected with a rotary shaft, a micro-controller—a ring magnet coaxially installed on the digital counting wheel, and a tunneling magnetoresistive angular displacement sensor installed radially displaced from the central axis of the annular magnet; the tunneling magneto-resistive angular displacement sensor and the ring magnet are separated by a certain distance in the direction parallel to the central axis of the ring magnet; the micro-controller is connected to the tunneling magnetoresistive angular displacement sensor and used to convert the output of the tunneling magnetoresistive angular displacement sensor into a readable number. The device uses the tunneling magneto-resistive angular displacement sensor to sense the angle of a rotary magnetic field generated by the rotation of the ring magnet which is installed on the digital counting wheel in order to permit the code of the digital counting wheel to be determined when the meter is read, thus realizing a direct read metering function. This direct read metering function is applied to provide a direct read water meter.
