Abstract

An industrial meter has wireless communication circuitry for communicating with a remote communication device. A repeater device allows the wireless communication circuitry of the industrial meter to continue to communicate with the remote communication device when the meter device is positioned in a location where direct communication between the wireless communication circuitry and the remote communication device is not possible (such as for example when the industrial meter is located underground).
