摘要： 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.

摘要： An arrangement includes a pipeline and a Coriolis volumetric flow meter for measuring a mass flow rate of a medium flowing through the pipeline. A first pressure sensor is attached at an inlet-side of the pipeline and a second pressure sensor is attached at an outlet-side of the pipeline, or wherein a differential pressure sensor is configured to detect a difference between an inlet-side and an outlet-side. The pressure sensors and/or the differential pressure sensor are configured to measure a media pressure and to determine, for each differential pressure, a volumetric flow velocity of the medium through the pipeline. A first monitoring sensor is attached at an inlet-side portion of the pipeline and a second monitoring sensor is attached at an outlet-side portion of the pipeline, wherein the monitoring sensors are configured to monitor a measurement variable different from the media pressure to identify a static media state.

摘要： The flow measuring system comprises a measuring transducer having a tube arrangement to convey a flowing fluid, an exciter arrangement for forced mechanical oscillations of the tube arrangement, and a sensor arrangement for registering mechanical oscillations of the tube arrangement. The measuring system further comprises a measuring and operating electronics electrically coupled with the exciter arrangement and the sensor arrangement. The measuring system has two driver circuits and two measurement transmitter circuits. The tube arrangement includes two flow dividers and four connected tubes adapted to be flowed through by the measured substance. The exciter arrangement includes two oscillation exciters, and the sensor arrangement includes four oscillation sensors. The first measurement transmitter circuit processes measurement signals from two oscillation sensors and outputs such to the second measurement transmitter circuit The second measurement transmitter circuit processes oscillation measurement signals of the other two oscillation sensors and ascertains total flow measured values.

摘要： 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.

摘要： A method for determining a flowed amount of a medium includes using a first flow measuring transducer according to a first measuring principle and a second flow measuring transducer according to a second measuring principle. The measured values of the first transducer are more reliable in first states of the medium than measured values of the second transducer, and the second measured values are more reliable in second states than the first measured values. A contribution to the flowed amount is ascertained based on the more reliable measured values. The contribution to the flowed amount based on the second measured values is ascertained via a transfer function. An updated version of the transfer function is ascertained when the first measured values are more reliable, and the flowed amount earlier ascertained based on the second measured values is corrected as a function of the updated transfer function.
