Abstract: The present disclosure relates to a method used to monitor a Coriolis mass flow meter, which has an oscillator with at least one measurement tube, the method including: exciting the oscillator so as to cause flexural vibrations of a first antisymmetric vibration mode by an excitation signal at a resonance frequency of the first antisymmetric vibration mode; sensing a vibration amplitude of the first antisymmetric vibration mode at the resonance frequency of the first antisymmetric vibration mode; sensing a time constant of the decaying free vibrations of the first antisymmetric vibration mode; and determining a modal elastic property of the oscillator with respect to the first antisymmetric vibration mode on the basis of the vibration amplitude of the first antisymmetric vibration mode, the excitation signal, and the time constant.

Abstract: Disclosed is a device for measuring fill level of a liquid comprising: a measuring tube having a tube wall extending between first and second terminal openings and which surrounds a volume for guiding the liquid, wherein a tube axis extends between the two tube openings; a first conductor extending at least sectionally around the volume and is electrically insulated from the volume; a second conductor extending at least sectionally around the volume and is electrically insulated from the first conductor and from the volume, wherein the two conductors extend essentially in parallel with one another and form a waveguide for microwaves; an HF circuit for in-coupling a microwave signal into the waveguide and for receiving reflected microwave signals out-coupled from the waveguide; an operating and evaluating circuit for determining fill level of the liquid in the measuring tube based on received microwave signals.

Abstract: An adapter includes several connecting nozzles. Free nozzle ends of the connecting nozzles are adapted to be connected to line ends of fluid lines. The adapter includes, for guiding flowing fluid in and then out, two mutually separated, tubular flow channels. Moreover, the adapter includes a projection, which extends from the nozzle end with a length to a free projection end remote therefrom. A fluid line system formed by means of the adapter comprises, furthermore, a fluid line with, enveloped by a wall, a lumen. The fluid line can be connected with its line end to the connecting nozzle of the adapter in such a manner that the projection protrudes inwardly into the lumen of the fluid line to form two tubular chambers of the fluid line mutually separated by the projection and adapted for guiding through flowing fluid.

Abstract: The measuring system includes a transducer apparatus with two tubes. Each tube is adapted to be flowed through by a fluid from an inlet end toward an outlet end and to be caused to vibrate. An electromechanical exciter mechanism excites and maintains mechanical oscillations of each of the tubes, and a sensor arrangement registers mechanical oscillations of at least one of the tubes. The transducer apparatus includes two temperature sensors each being mechanically and thermally conductively coupled with a wall of the tube, wherein each of the temperature sensors registers a measuring point temperature, and converts such into a temperature measurement signal temperature. A measuring and operating electronics (ME) generates a transducer temperature measured value representing a transducer apparatus temperature so that a magnitude of the transducer temperature measured value is greater than a magnitude of the measuring point temperature and less than a magnitude of the measuring point temperature.

Abstract: A method for monitoring flow of a medium by means of a pressure difference measuring device and a Coriolis mass flowmeter having two oscillators, which comprise, in each case, a bent measuring tube pair, which are arranged on top of one another and connected for parallel flow between the two pressure measuring points of the pressure difference measuring device, comprising steps as follows: Registering a pressure difference between the first pressure measuring point and the second pressure measuring point; registering a first density measured value based on at least a first oscillation frequency of the first oscillator; registering a second density measured value based on at least a second oscillation frequency of the second oscillator; ascertaining a flow measured value based on the pressure difference, when a difference between the first density measured value and the second density measured value is less than a density difference limit value.

Abstract: An assembly comprises
circular panel an annular body; and an elastomer.
The annular body has a panel seat surrounded by a lateral surface having a ring shaped, surrounding, outer groove bounded in a first axial direction by a first outer shoulder and bounded in an opposing, second axial direction by a second outer shoulder.
Adjoining the first outer shoulder is a guide surface having a radius monotonically increasing with separation from the first shoulder.
The circular panel has an outer lateral surface having a peripheral inner groove extending radially inwards.
The two inner shoulders have a convex contour in which the rotational axis of the circular panel extends.
The elastomer ring is clamped between both inner shoulders and both outer shoulders, whereby a shifting of the circular panel out of the annular body is prevented up to a limit loading.-

Abstract: Disclosed is a sensor arrangement on a process installation comprising at least two sensor tiles, wherein each sensor tile comprises a support and a plurality of sensors arranged on the support for determining a physical or chemical variable of a measuring medium, a process characteristic of the measuring medium, and/or a state of the process installation. A first sensor tile comprises a control unit having a transmit and receive module for data exchange with a control unit of a second sensor tile. The first control unit of the first sensor tile and/or a second control unit allocated to the sensor arrangement is designed to weight the values determined by each sensor tile. Weighting may be a function of the measured value variations of the sensor tile, the position of the sensor tile in the process installation, and/or the function of the sensor tile.
