Abstract: The measuring system comprises a vibration-type measuring sensor, a sensor housing, a magnetic-field detector, and measuring-system electronics electrically coupled both to an oscillation exciter and to oscillation-sensing devices of the measuring sensor. The measuring sensor is inside the sensor housing and the magnetic-field detector is outside the sensor housing. The magnetic-field detector is designed to convert changes in the magnetic field into a magnetic-field signal having an amplitude dependent on a magnetic flux through the magnetic-field detector and/or on an area density of said magnetic flux. The measuring-system electronics are designed to determine, on the basis of oscillation measurement signals of the measuring sensor, the mass-flow-rate measurement values representing the mass flow rate and to at least qualitatively determine, on the basis of the magnetic-field signal, whether an external magnetic field is established inside the measuring sensor.

Abstract: A fluid line system includes a fitting having a lumen extending from first and second flow openings to a third flow opening located in a remote fitting end; first and second fluid lines, each having a lumen; and a flow-conditioner element inserted into the lumen of the fitting and non-detachably connected thereto and has first and second flow channels connected fluidically in parallel. Each of the two flow channels of the flow-conditioner element extends from a first flow opening located in a region of its element end to a second flow opening located in a region of its opposite element end, and the flow-conditioner element is positioned and oriented in the fitting such that a first flow path includes both the first flow channel and the first fluid line, and a second flow path includes both the second flow channel and the second fluid line.

Abstract: A method for detecting a foreign body in a flowable medium includes determining a first time curve of a first measured value using a first measuring device for determining a physical density of the medium. The method also includes determining a second time curve of a second measured value using a second measuring device for ascertaining a relative permittivity of the medium. A temporal correlation between the first curve and the second curve is determined, and pairs of measured values of the first measured value and the second measured value are detected. The method further includes checking whether the detected pairs of measured values within a predefined tolerance interval correspond to the correlation of at least one predefined function. If this is not the case, it is established that the foreign body is present in the medium.
