A meter is provided having a communication interface for receiving and interfacing with a communication device for transmitting measurement and other data to a central computer station via the communication device. The meter includes a measurement module for obtaining measurement data and a processor having a memory for storing application software for communicating the measurement and other data to the communication interface. The data are then provided to the communication device via the communication interface. The communication device is preferably a plug-and-play PCMCIA-type card or other type of memory card having a processor and a connection port for connecting to a port adaptor of the communication interface for receiving the data via the connection port-port adaptor connection. The communication device further includes communication circuitry for communicating the received data to the central computer station via one or more communications networks according to a communications protocol pre-programmed within the processor.
