The meter reader comprises a data logger, an isolation barrier, a regeneration unit a communication controller. The isolation barrier can be an optical isolator, providing electrical isolation greater than 10kV (rms). The invention removes the requirement for a separate isolation component, such as a chatterbox, to be placed between the data logger and the utility meter and provides a reader that is efficient and cost effective to install and maintain. |
