Definitions

  • Flow measuring device as well as a measuring device itself.
  • the invention relates to a method for monitoring a measuring device, in particular a flow measuring device, and a measuring device itself, according to the preamble of claims 1 and 8.
  • Measuring device monitors are widely known. This applies in particular to measuring devices that are connected to a bus system, via which measurement data are transported in one direction and control data in another direction.
  • the invention relates in particular to flow measuring devices, and such a control mode can also be applied to other measuring devices, provided that these measuring devices determine measurement data from an analysis or a process.
  • measuring devices determine the flow velocity in a pipeline in a known manner based on the principle of the Karman vortex street:
  • a flow obstacle in the pipeline segment of the measuring device generates periodic vortices downstream, the frequency of which is a measure of the flow velocity.
  • tapping of the periodic vortices eg using a paddle or an ultrasonic sensor
  • Flow measuring devices strongly depend on the physical state of the fluid. For example, have
  • Installation instructions do not guarantee that reliability will not be affected by such effects. Furthermore, it is sometimes difficult for experienced professionals to recognize the presence of disruptive effects. For example, even relatively slight canting during installation leads to additional eddy formation in the fluid, which overlap with the actual, desired, measurement signal and influence the measurement accuracy.
  • the invention is therefore based on the object of demonstrating a method and a measuring device itself with which such measurement errors due to incorrect installation can be reliably avoided.
  • the essence of the method according to the method is that a characteristic quantity is calculated from a time series s (t) of the measurement signal of a measuring device, which parameter is compared with previously recorded reference values, and a message is automatically generated based on this whether the measuring device has been installed properly or incorrectly.
  • An advantageous embodiment of the invention is that the reference values are previously recorded in relation to the respective measuring device and are correspondingly assigned to the device. In this way, even with a plurality of such measuring devices in operation, the reference values associated with the respective measuring device can be reliably assigned.
  • the installed state determined by comparison is automatically created as a message and displayed on the measuring device. In this way, the operator is automatically shown a message about the correct installation or, if it occurs, about the incorrect installation.
  • the installed state determined by comparison is automatically generated as a message and sent to a higher-level system by means of information transmission and displayed there. This means that the installation errors, if they occur, can be displayed at a control center. These are then displayed so that the affected device can be located and the installation error can be remedied.
  • one or more measuring devices operating in this way are connected to the higher-level system via a bus system.
  • a suitable information technology connection of all connected measuring devices and devices takes place via this.
  • the message is generated automatically as a full text message. Thus, a safe and understandable message is transmitted to possibly inexperienced personnel and understood by them.
  • the message automatically generates a corresponding additional full-text message with troubleshooting instructions. In this way, maintenance or rectification of the installation error is particularly simple.
  • the essence of the invention is that from a time series s (t) of the measuring signal of the measuring device in a calculation unit, a parameter can be calculated in a microprocessor that is comparable to reference values previously recorded and stored in a data memory, and based on this, a message can be generated automatically as to whether the measuring device has been installed correctly or incorrectly. In this way, any and all installation errors are reliably and, above all, automatically indicated, so that measurement errors caused by incorrect installation can be reliably avoided.
  • the measuring device has a comparator which compares the time series s (t) of the measurement signal with the data from the data memory.
  • the measuring device contains a display on which said messages can be displayed.
  • the display is one of the actual ones
  • Measuring device is located remotely located display. In a further advantageous embodiment, it is indicated that the individual elements of the measuring device are housed compactly in one device.
  • the individual elements of the measuring device are at least partially spatially separated, but are connected to one another via an information system.
  • the device is advantageously implemented as a microprocessor with a memory unit (e.g. for the temporary storage of parameters).
  • the time series s (t) is digitized for processing if this has not already been done by the transmitter.
  • the reference values (4) are stored in a database.
  • the characteristic (2) is, for example, the diffusion constant D of the phase angle ⁇ of the signal s.
  • D ( ⁇ ) is chosen as a parameter
  • typical values of D ( ⁇ ) are disadvantageous as reference values (4) Installation conditions filed.
  • the reference values were determined experimentally using the described method under specific disadvantageous installation conditions (eg from the manufacturer) and are stored in a non-volatile memory. They serve as "fingerprints”: if, for example, a parameter D ( ⁇ ) determined during operation is comparable to that generated under tilted installation, this is recognized by the comparator (3) and an error message of the type "tilted installation” is output accordingly. If, on the other hand, the parameter D ( ⁇ ) is comparable to the parameter stored under "error-free installation", no error message is generated or the status message "error-free installation” is output.
  • the comparator calculates the similarity of the current parameter with the reference values using a suitable metric. Average square distance, difference or similar sizes are suitable for this.
  • the error message can be output on a display on the transmitter or transmitted to a downstream system (e.g. control system or handheld device) for further processing (e.g. via fieldbus or wireless).
  • a downstream system e.g. control system or handheld device
  • further processing e.g. via fieldbus or wireless

Abstract

L'invention concerne un procédé pour surveiller un dispositif de mesure, notamment un débitmètre, ainsi que le dispositif de mesure lui-même. L'objectif de l'invention est d'éviter de manière fiable des erreurs de mesure dues à une erreur de montage. A cet effet, une grandeur caractéristique est calculée à partir d'une série chronologique s(t) du signal mesuré par un dispositif de mesure, ladite grandeur caractéristique étant comparée à des valeurs de référence enregistrées au préalable. Sur la base de cette comparaison, un message, indiquant si le montage du dispositif de mesure est effectué de manière correcte ou non, est généré automatiquement.
