Claim Text:
1. A level measuring system, comprising: a level measuring device; and a control unit connected to the level measuring device via a communication interface; wherein the level measuring device is configured to determine one of (a) whether a current measured value, recorded by the level measuring device in a measurement, differs from a measured value recorded in the measurement preceding this measurement; (b) whether a current item of diagnostic information, generated by the level measuring device, differs from an item of diagnostic information preceding this item of diagnostic information; and (c) whether a current device parameter has changed due to another device parameter changing; wherein the control unit is configured to retrieve one of (a) the current measured value, (b) the current item of diagnostic information and (c) the current device parameter from the level measuring device only when the level measuring device has established one of (A) a difference between one of (1) the measured values and (2) the items of diagnostic information and (B) the device parameter has changed; wherein upon determining that one of the current measured value, the current item of diagnostic information and the current device parameter has changed, the level measuring device records this fact in a flag; and wherein the control unit retrieves the flag and, after checking the flag, decides whether or not one of the current measured value, the current item of diagnostic information and the current device parameter is to be retrieved from the level measuring device.
