Method for collecting data in connection with a consumption, a physical or physico-chemical parameter and/or an operating state during operation of a local sensor, preferably a sensor for a consumption meter, as part of a supply network which comprises at least one local sensor, preferably a plurality of local sensors, and is intended to distribute a consumable, wherein the sensor contains a measuring element, the measuring element of the respective sensor provides elementary measuring units, which correspond to at least one physical or physico-chemical variable or at least one physical or physico-chemical parameter, as raw measurement data, and the sensor comprises radio communication means and storage means, wherein in order to determine the measurement resolution of the sensor, the conditions for generating time stamps are stipulated in advance using a correlation model, time stamps of successive raw measurement data are generated in the sensor on the basis of the correlation model, the time stamps are transmitted via a wired connection and/or via a radio path, with the result that the raw measurement data acquired by the measuring element are reconstructed and evaluated on the basis of the time stamps using the correlation model, and wherein the sensor is connected to a data collector via a primary communication path, a tertiary communication path is provided between the data collector and a head end, and the time stamps transmitted by the sensor are collected, stored and/or evaluated in the data collector and/or in the head end, characterized in that the conditions for generating time stamps can be changed dynamically in terms of time within the framework of the correlation model, wherein the data collector and/or the head end change (s) the conditions for generating time stamps by virtue of the data collector and/or the head end determining or dynamically changing the conditions for generating time stamps and transmitting said conditions to the sensor, a plurality of time stamps are each transmitted as a data packet (17 i, 17 i+n) along the primary communication path, wherein a data packet respectively contains a plurality of time stamps (TS1-TSn), and the determination of when a data transmission should be carried out by the sensor depends on whether a predefined quantity of in particular compressed collected time stamps has been reached since the previous data transmission. the sensor contains a measuring element, the measuring element of the respective sensor provides elementary measuring units, which correspond to at least one physical or physico-chemical variable or at least one physical or physico-chemical parameter, as raw measurement data, and the sensor comprises radio communication means and storage means, wherein in order to determine the measurement resolution of the sensor, the conditions for generating time stamps are stipulated in advance using a correlation model, time stamps of successive raw measurement data are generated in the sensor on the basis of the correlation model, the time stamps are transmitted via a wired connection and/or via a radio path, with the result that the raw measurement data acquired by the measuring element are reconstructed and evaluated on the basis of the time stamps using the correlation model, and wherein the sensor is connected to a data collector via a primary communication path, a tertiary communication path is provided between the data collector and a head end, and the time stamps transmitted by the sensor are collected, stored and/or evaluated in the data collector and/or in the head end, a tertiary communication path is provided between the data collector and a head end, and the time stamps transmitted by the sensor are collected, stored and/or evaluated in the data collector and/or in the head end, characterized in that the conditions for generating time stamps can be changed dynamically in terms of time within the framework of the correlation model, wherein the data collector and/or the head end change (s) the conditions for generating time stamps by virtue of the data collector and/or the head end determining or dynamically changing the conditions for generating time stamps and transmitting said conditions to the sensor, a plurality of time stamps are each transmitted as a data packet (17 i, 17 i+n) along the primary communication path, wherein a data packet respectively contains a plurality of time stamps (TS1-TSn), and the determination of when a data transmission should be carried out by the sensor depends on whether a predefined quantity of in particular compressed collected time stamps has been reached since the previous data transmission.
