摘要： A method for operating a Coriolis mass flow rate meter and a Coriolis mass flow rate meter including an evaluation device, a measuring tube having a medium flowing therethrough and which is excited so as to perform oscillations, and at least two spaced oscillation pickups spaced apart in the longitudinal direction of the measuring tube to each generate an oscillation signal, wherein a first indicator variable based on the damping of the oscillations of the measuring tube is initially used to detect deposits in the measuring tube and if, based on the first indicator variable, increased damping is established, a second indicator variable is used, which is based on the manifestation of harmonics in the frequency spectrum of an oscillation signal such that reliable detection of deposits and therefore an indication of the state of meters and pipelines in a process engineering installation are advantageously possible.

摘要： Improved identification of a process anomaly in a technical facility includes training a self-organizing map using the historical process data as good states of the facility. The good states are used to determine a temporal sequence or a path of node hits and the tolerances of neuron hits. Threshold values are determined and stored for a Euclidean distance for the good states. The Euclidean distance of a current state vector to the neuron hit is checked as to whether the threshold value has been exceeded. The path determined is used to determine the neuron to be hit as long as the threshold value was not already exceeded in the check on the relevant neuron. A symptom vector from the current state vector and either the neuron hit or the neuron that is to be hit is determined.

摘要： A method and Coriolis mass flowmeter, wherein the Coriolis mass flowmeter includes at least one measurement tube through which a medium flows, at least one exciter system arranged in the central region of the at least one measurement tube which causes the measurement tube to oscillate, and at least two oscillation pick-ups arranged in front of and behind the at least one exciter system. The at least two measurement tubes are additionally each provided with at least one acceleration sensor arranged in front and/or behind the exciter system. An evaluation device is configured to receive acceleration signals from the acceleration sensors and evaluate the acceleration signals to diagnose an asymmetry in the measurement tubes such that fault states, such as deposits in one of the two measurement tubes, blockage of a tube in a flow divider or asymmetrical changes in the ability of the measurement tubes to oscillate, such as due to cracks or fractures, can advantageously be detected.

摘要： For supporting fault diagnosis of an industrial installation having a plurality of installation components connected via a pipeline system, provision is made for assigning each installation component to one of a plurality of abstract component types, where a weighted directed component graph is in turn assigned to each component type. A piping and instrumentation flow diagram of the industrial installation is processed component by component proceeding from a start point along a pipeline system. Here, in the case of each installation component, the component graph of the installation component assigned according to the component type is accessed. The individual component graphs are joined together to form a system of weighted directed overall graphs of the industrial installation, the nodes of which are each assigned to a plurality of individual installation components.
