Abstract
The method and devices for remote metering the consumption, of utilities according to the present invention provide the possibility to retrieve a specific amount of data, i.e. consumption data and/or additional data, from remote meters of a remote metering system. The retrieved data provide a data profile in a given time interval than the entire buffer, for example indicative of the consumption characteristics over time at the location of a remote meter or, in the case of a distribution network for electric energy, indicative of a ratio of active and reactive energy consumption at the location of a remote meter over time.
