Abstract

A flow meter monitoring system (100) is provided according to an embodiment of the invention. The flow meter monitoring system (100) includes a communication interface (101) configured to communicate with one or more flow meters and receive meter calibration values for a flow meter of the one or more flow meters. The flow meter monitoring system (100) further includes a processing system (102) in communication with the communication interface (101) and configured to receive the meter calibration values from the communication interface and correlate the meter calibration values to known meter calibration values (114) in order to determine the flow meter type.

Claims
