Abstract
A fuel flow meter assembly for detecting fraud caused by tampering. The fuel flow meter assembly includes a fuel flow meter comprising a shaft and a displacement sensor operatively connected to the fuel flow meter shaft for generating information representative of an amount of fuel delivered through the fuel flow meter. At least one transponder is coupled with one of the fuel flow meter shaft and the displacement sensor. At least one interrogator electronics is coupled with the other of the fuel flow meter shaft and the displacement sensor. The at least one interrogator electronics is configured for remote electronic communication with the at least one transponder.
