Embodiments for rotation sensing are provided. The device may include a magnet apparatus comprising a magnet, the magnet apparatus configured to be coupled to a dial apparatus of a meter. Also included may be a magnetic field sensor configured to be coupled to a dial cover. When the magnet apparatus is coupled to the dial apparatus and the magnetic field sensor is coupled to the dial cover, the distance between the magnet and the magnetic field sensor may be a function of the strength of the magnet and the sensitivity of the magnetic field sensor. Also, the magnetic field sensor may be configured to generate an analog signal. The device may also include a memory component storing logic configured to detect an abnormal condition based on a data value of the analog signal. The detected condition may be magnetic tampering, a missing dial cover, and/or a missing dial hand.
A rotation sensing device, comprising:
A method for sensing the rotation of a dial apparatus of a metering device, comprising:
A system for rotation sensing, comprising:
