A method for distinguishing between the presence of a foreign body and a gas bubble in a flowable medium in a pipeline or a container includes evaluating received microwave signals, wherein mechanical vibrations are introduced into the medium by means of which a gas bubble present in the medium is set into vibration. A gas bubble is detected only in the event that when mechanical vibrations are introduced and the received microwave signals or the value derived therefrom is/are modulated; otherwise, a foreign body is detected. Also disclosed is a system which is suitable for carrying out the method according to the present disclosure.

A system for managing data of an automation field device in a secure manner includes a decentralized distributed ledger-type database, or blockchain, comprising a plurality of subscriber nodes, comprising validation-capable subscriber nodes and an automation field device with an electronic unit. The electronic unit is designed to run a distributed ledger software stack. The field device generates data, comprising measurement values and/or calibration certificates requiring verification, and the field device operates as a light node of the decentralized database after running the distributed ledger software stack and is designed to transmit the data to the decentralized database via the communication network and write said data in encrypted form into the decentralized database. The validation-capable subscriber nodes validate the transmitted data, and the decentralized database is designed to store the data if at least a specified proportion of the validation-capable subscriber nodes successfully validate the data.

A flange for a corrosion resistant and nevertheless low cost flange for pressure measurement cells, or pressure transfer means, is composed essentially of a metal foundation of a standard material and is protected on the side facing a process medium by a there applied layer of a highly alloyed, special material.
