Abstract: The present disclosure relates to a method for measuring flow velocity or volume flow of a medium using a magneto inductive flow measuring device and to an arrangement having a magneto inductive flow measuring device, as well as to a filling plant with an arrangement, wherein the medium has a low conductivity. A high accuracy of measurement is achieved by provision of a first narrowing of a medium-containing pipeline and/or a second narrowing of a medium-containing measuring tube, wherein the pipeline leads the medium to a measuring tube of the flow measuring device.

Abstract: A magneto-inductive flow measuring device for ascertaining flow of a measured medium through a measuring tube having a measuring tube axis, comprising: at least a first coil component having a coil body for accommodating a coil core of a coil. The coil is wound on the coil body and the coil core is arranged in a first passageway of the coil body with a longitudinal axis of the coil core coaxial with the coil. At least two cable strands are arranged between the coil core and the coil body, wherein the cable strands serve for tapping the signal of two or more measuring electrodes arranged on the measuring tube. The cable strands extend within the coil component essentially along a cutting plane, which extends perpendicular to the measuring tube axis.

Abstract: An automation field device includes a measuring tube for conducting a flowable medium; a measuring assembly for ascertaining a measurement variable of the medium, said measuring assembly at least partly arranged on the measuring tube; and a housing for accommodating at least one electronic component for operating the measuring assembly and arranged on an outer lateral surface of the measuring tube and at least partly covering the measuring assembly. The housing includes a housing wall which, together with the outer lateral surface of the measuring tube, delimits a housing interior and includes a first edge section, which is at least partly in direct contact with the outer lateral surface and is at least partly curved away from the housing interior. At least the first edge section is braced together with the measuring tube in a force-fitting manner.

Abstract: The present disclosure relates to a high-frequency plug connection for high-frequency-based field devices, consisting of plugs and corresponding sockets. The high-frequency plug connection is characterized in that the at least one plug is resiliently enclosed by an enclosure such that this/these plug(s) is/are moveable radially with respect to its/their plugging axis. This has the advantage of reducing the risk of jamming against the enclosure when the plugs are inserted in the corresponding sockets, during fastening of the circuit board substrate on which the sockets are arranged. A modular design of the high-frequency-based field device, and the manufacturability thereof, are simplified as a result.
