Abstract: A measuring transducer serves for producing vibration signals corresponding to parameters of a flowing medium comprises a measuring transducer housing having housing ends and, extending within the measuring transducer housing between its housing ends, a tube arrangement formed by means of at least two tubes. Of the two tubes, at least one tube serves as a measuring tube conveying flowing medium and the other tube is mechanically connected with the tube by means of a first coupling element to form an inlet-side coupling zone and by means of a second coupling element to form an outlet-side coupling zone. At least the first coupling element has in a region extending between the tubes a slit having at least one closed end. Slit has a maximal slit width and a maximal slit length, which is greater than the maximal slit width. Placed partially within the slit is a connecting element, which contacts a slit edge enclosing said slit.

Abstract: A measuring arrangement of the invention includes: At least one measuring device, which generates, repeatedly during operation, measured values, especially digital, measured values, representing the at least one measured variable to be registered; as well as an electronic data processing system superordinated to the at least one measuring device, especially a data processing system which is spatially distributed and/or spatially remote from the measuring device. Measuring device and data processing system are connected together by means of at least two line-pairs, through each of which an electrical current flows, at least at times, during operation. According to the invention, the measuring device transmits the internally generated, measured values to the data processing system via both line-pairs. In this way, it is then possible to transmit a plurality of measured values simultaneously, when each of the two line-pairs is embodied as part of a two-conductor current-loop.

Abstract: An ultrasonic transducer for an ultrasonic flow measuring device, comprising a first housing part and a second housing part. The second housing part is axially guided in the first housing part and is so biased relative to the first housing part that, in a first state of the ultrasonic transducer, a first axial stop of the second housing part rests on a first axial stop of the first housing part, wherein, by applying, counter to the bias, a predetermined force on a second axial stop of the second housing part, the second housing part is axially shiftable, so that, in a second state of the ultrasonic transducer, the first axial stop of the second housing part is moved out of the first state.
