Abstract:
1. A method based on a communication and data network for automatic time synchronization of fill-level measuring devices, pressure measuring devices, and field control units by a central server, comprising: determining a current time value by at least one of the fill-level measuring devices, the pressure measuring devices, and the field control units; transmitting the current time value to the server; providing a desired value in the central server; comparing the current time value with the desired value by the central server, the comparing being performed at the server; wherein the server ensures that a correct conversion of the current time of day of the at least one of the fill-level measuring devices, the pressure measuring devices and the field control units is carried out, when the desired value differs from the current time value by more than a predetermined threshold value, requesting, by the server, the at least one fill-level measuring device, pressure measuring device, and field control unit to carry out the time synchronization, after which that at least one fill-level measuring device, pressure measuring device, and field control unit sets the current time value to the desired value. wherein the server takes over data from at least one of the fill-level measuring devices, the pressure measuring devices, or the field control units into a database only when the desired value differs from the current time value at most by the predetermined threshold value.
