Abstract
A fuel dispenser with a flow meter prevents fraud in the form of flow meter replacement by storing a unique identifier in the memory associated with the flow meter. The unique identifier is stored in the memory of the fuel dispenser as well. Prior to each fueling transaction, the unique identifiers in the respective memories are compared. In the event that a match is not found, an alarm may be generated. A calibration factor may likewise be stored in both memories and compared concurrently with the unique identifiers. In an alternate embodiment, each element of the flow meter has a unique identifier which is compared prior to a fueling transaction.
