Abstract: A method operates a supply system having a measuring unit and a central unit. Information is transferred repeatedly at specific time intervals via a communication network by radio between the central unit and the measuring unit. The measuring unit or the central unit receives the information and then generates a receipt confirmation, which it transmits to the central unit or the measuring unit respectively.

Abstract: A method collects data during operation of a local sensor as a component of a supply network for distributing a consumable. The supply network contains a master in communication with the local sensor via a primary communication path. The sensor contains a measuring element which supplies, as raw measurement data, elementary measurement units. A wired primary communication path is provided between the sensor and the master.
