An encoder to be mounted to a shaft extending from a piston meter configured to compute a volume of distributed fluid includes a magnet affixed to the shaft via a floating magnet holder, a magnetic sensor configured to sense the flux density and direction of a magnetic field created by the magnet and to output a signal indicating the flux density and direction of the magnetic field to a printed circuit board, and the printed circuit board configured to output a signal indicating the volume of distributed fluid if the encoder has not been tampered with and configured to output an error signal if the encoder has been tampered with.

Encoder using magnet drop out feature for theft detection

An axial flow meter includes a housing including a generally elongated body with a continuous internal bore. Two spindles are mounted parallel to one another in the housing. Each spindle has a blade on the exterior surface of the spindle. Blades on each of the two spindles engage with each other. Bearings at each end of both spindles engage the spindles. At least one of the bearings engaging each one of the spindles is fixed in a position relative to the elongated body thereby preventing axial movement of the two spindles while allowing rotational movement of the two spindles.
