Method for operating a consumption measuring device, in particular heating cost distributor

摘要

The method involves storing data of different data types over time by an electrical energy source (6) e.g. battery. The stored data is transferred occasionally and periodically to a mobile data collector (7) from time to time by the source. Data type of the transmitted data is determined. Transmission frequency is computed based on a limited time period and the electricity of the energy source in the period. The data of the selected data types are transmitted according to the time period to maximally use the available electricity of the energy source.
