Abstract: An automation technology field device includes operating electronics and a plurality of parameters. The operating electronics are designed to operate the field device based on the parameters and obtain and process data based on the parameters. A firmware is a software container allocated to the operating electronics. The software container is designed to execute the installed code to establish, using the code, a communication connection to a distributed ledger via at least one of the outputs is a higher-level communication network, to integrate the field device in the distributed ledger-and to process and/or combine at least one part of the obtained and processed data into result data and to transmit the result data to the distributed ledger.

Abstract: A method of determining an interface height in a container of a thickener includes measuring said interface height with a level measurement device during time periods, when conditions permit, measuring process variables related to the thickening process performed by the thickener and calculating and providing a calculated interface height, wherein a calculating unit is designed to learn said calculation based on said measured interface heights and said measured process variables.

Abstract: Measuring transducer of the vibration type for measuring a mass flow of a flowing medium. The measuring transducer includes two straight measuring tubes for conveying the medium, wherein the measuring tubes are arranged in parallel to one another and the measuring transducer is embodied with micromechanical construction. The measuring transducer of the vibration type of the invention permits reliable measurement of the smallest mass flows of a flowing medium in the form of, for example, a liquid or a gas.
