Abstract

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.

Description

[0001] related application [0002] This application claims priority to Provisional Patent Application Serial No. 61 / 289,756, entitled "Encoder Using Magnet Dropout Feature to Detect Theft," filed December 23, 2009, and Provisional Patent Application Serial No. 61 / 291,506, entitled "Encoder Using Magnet Dropout Feature to Detect Theft," and U.S. Patent Application Serial No. 12 / 952,496, filed November 23, 2010, entitled "Using Magnet Encoders that Drop Out Feature Detect Theft", the subject matter of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to fluid dispensing systems and, in particular, to encoders for measuring the output of fluid dispensing systems. Background technique [0004] Fluid dispensing systems typically utilize encoders to measure the amount of fluid dispensed. These encoders are often paired with a fluid metering device, for example, the shaft of a piston flow meter, and are us...
