Definitions
- the present invention relates to a device for continuously measuring and displaying the relative concentration, in various places, of containers containing liquids or other products.
- a mechanical device causes a sensor to move inside a container until the value of the measured concentration corresponds to a predetermined value; the position of the sensor at this location can, in this case, provide a measurement of the sludge level.
- the measurement provided by a sensor is often unreliable because it can be subject to various causes of malfunction: fouling, various drifts originating from the product to be measured and from the industrial context in which it operates. These multiple causes of disruption constitute a handicap for the validity and security of use of the measure.
- the device, object of the present invention consists of a measurement pole which comprises several sensors arranged along the length of the pole. It also provides several measurements located at various locations in the container. The measurements are collected and represented on a display terminal. By visualizing with respect to vertical and horizontal coordinates, on the one hand, the height of the container, on the other hand, the measured relative concentration values, one obtains a curve which represents in real time the various states of concentration of what is contained.
- This device presents the 3 points of interest listed below.
- the device By highlighting the concentration curve obtained, the device allows a better understanding of the state of a contained process as well as of its evolution.
- the device makes it possible to locate one or more particular concentrations such as, for example, a level of mud, a level of foam, a level of predetermined concentration.
- the device clearly and immediately shows a possible measurement defect in one or other of the sensors. If the measurement of a sensor is erroneous, its representation compared to the measurements of the other sensors, in particular those located nearby, shows that this measurement is visibly erroneous. According to the invention, a device is therefore proposed which makes it possible to continuously display the relative concentration of a content.
- Figure 1 shows the device and its application. It consists of the 3 elements defined below.
- the measurement pole (1) comprises the relative concentration sensors distributed over its entire length.

Abstract
L'invention concerne un dispositif dont la fonction est de fournir une représentation des diverses concentrations contenues, par exemple, dans un bac. Cette représentation est obtenue en visualisant par rapport à des coordonnées verticales et horizontales, d'une part, la hauteur du bac, d'autre part, les valeurs de la concentration relative mesurée en divers endroits de cette hauteur. La courbe ainsi obtenue fournit une visualisation en temps réel des diverses concentrations ainsi que de leur évolution. Le dispositif est constitué d'une perche de mesures qui comporte les capteurs (1), d'un ensemble électronique (2) qui délivre les signaux destinés à la régulation (3) et à la transmission des mesures (4) et d'un terminal de visualisation (6).The invention relates to a device whose function is to provide a representation of the various concentrations contained, for example, in a container. This representation is obtained by visualizing with respect to vertical and horizontal coordinates, on the one hand, the height of the tank, on the other hand, the values of the relative concentration measured in various places of this height. The curve thus obtained provides a real-time visualization of the various concentrations as well as their evolution. The device is made up of a measurement stick which includes the sensors (1), an electronic assembly (2) which delivers the signals intended for the regulation (3) and the transmission of the measurements (4) and of a display terminal (6).
Description
Dispositif pour mesurer et visualiser en continu la concentration relative, en divers endroits, de récipients contenant des liquides ou autres produits. La présente invention concerne un dispositif pour mesurer et visualiser en continu la concentration relative, en divers endroits, de récipients contenant des liquides ou autres produits. Device for continuously measuring and displaying the relative concentration, in various locations, of containers containing liquids or other products. The present invention relates to a device for continuously measuring and displaying the relative concentration, in various places, of containers containing liquids or other products.
Actuellement, divers types de capteurs sont utilisés pour la mesure de concentration, selon l'application à laquelle ils sont destinés. Ils fournissent un signal de mesure ponctuelle qui peut être affiché et utilisé dans les boucles de régulation. Dans certains cas, pour la mesure d'un niveau de boue décantée par exemple, un dispositif mécanique fait se déplacer un capteur à l'intérieur d'un récipient jusqu'à ce que la valeur de la concentration mesurée corresponde à une valeur ptédéterminée; la position du capteur à cet endroit peut fournir, dans ce cas, une mesure de niveau de boue. Currently, various types of sensors are used for concentration measurement, depending on the application for which they are intended. They provide a point measurement signal which can be displayed and used in the control loops. In some cases, for measuring a level of settled sludge for example, a mechanical device causes a sensor to move inside a container until the value of the measured concentration corresponds to a predetermined value; the position of the sensor at this location can, in this case, provide a measurement of the sludge level.
La mesure fournie par un capteur est souvent peu fiable car celui-ci peut être sujet à diverses causes de mauvais fonctionnement : encrassements, dérives diverses provenant du produit à mesurer et du contexte industriel dans lequel il évolue. Ces causes multiples de perturbation constituent un handicap pour la validité et la sécurité d'utilisation de la mesure. The measurement provided by a sensor is often unreliable because it can be subject to various causes of malfunction: fouling, various drifts originating from the product to be measured and from the industrial context in which it operates. These multiple causes of disruption constitute a handicap for the validity and security of use of the measure.
Le dispositif, objet de la présente invention, est constitué d'une perche de mesures qui comporte plusieurs capteurs disposés sur la longueur de la perche. Il fournit a ins i plusieurs mesures localisées en divers endroits du récipient. Les mesures sont recueillies et représentées sur un terminal de visualisation. En visualisant par rapport à des coordonnées verticales et horizontales, d'une part, la hauteur du récipient, d'autre part, les valeurs de concentration relative mesurées, on obtient une courbe qui représente en temps réel les divers états de concentration de ce qui est contenu. The device, object of the present invention, consists of a measurement pole which comprises several sensors arranged along the length of the pole. It also provides several measurements located at various locations in the container. The measurements are collected and represented on a display terminal. By visualizing with respect to vertical and horizontal coordinates, on the one hand, the height of the container, on the other hand, the measured relative concentration values, one obtains a curve which represents in real time the various states of concentration of what is contained.
Ce dispositif présente les 3 points d ' i ntérêt
énumérés ci-dessous. This device presents the 3 points of interest listed below.
1. Par la mise en évidence de la courbe de concentration obtenue, le dispositif permet une meilleure connaissance de l'état d'un processus contenu ainsi que de son évolution. 1. By highlighting the concentration curve obtained, the device allows a better understanding of the state of a contained process as well as of its evolution.
2. Le dispositif permet de localiser une ou plusieurs concentrations particulières telles que, par exemple, un niveau de boue, un niveau de mousse, un niveau de concentration prédéterminée. 2. The device makes it possible to locate one or more particular concentrations such as, for example, a level of mud, a level of foam, a level of predetermined concentration.
3. Le dispositif fait apparaître clairement et immédiatement un défaut éventuel de mesure de l'un ou l'autre des capteurs. Si la mesure d'un capteur est erronnée, sa représentation par rapport aux mesures des autres capteurs, notamment ceux se situant à proximité, fait apparaître que cette mesure est visiblement erronnée. Selon l'invention, on propose donc un dispositif permettant de visualiser en continu la concentration relative d'un contenu. 3. The device clearly and immediately shows a possible measurement defect in one or other of the sensors. If the measurement of a sensor is erroneous, its representation compared to the measurements of the other sensors, in particular those located nearby, shows that this measurement is visibly erroneous. According to the invention, a device is therefore proposed which makes it possible to continuously display the relative concentration of a content.
La figure 1. représente le dispositif et son application. Il est constitué des 3 éléments définis ci-dessous. Figure 1. shows the device and its application. It consists of the 3 elements defined below.

The measurement pole (1) comprises the relative concentration sensors distributed over its entire length. The constitution of this pole and its dimensions, the number, the type, and the distribution of the measurement sensors depend on the application concerned.
2. L'ensemble électronique (2) comporte les éléments nécessaires pour assurer les fonctions suivantes : 2. The electronic assembly (2) includes the elements necessary to perform the following functions:

Le terminal (6) comportant un dispositif de visualisation ( moniteur vidéo ) qui recueille les mesures transmises. La visualisation est effectuée en fa i sant apparaître sur une image comportant une coordonnée de dimension ( hauteur du récipient, par exemple ) et une coordonnée de concentration relative, les mesures transmises. On obtient ainsi des points correspondant à une courbe représentative de létat de concentration relative du contenu du récipient. Selon l'application, divers types de représentation peuvent être retenus. - the calculations, on the basis of the measurements provided, making it possible to detect and determine the position of one or more measurements of predetermined characteristic concentrations (for example: position of the sludge height); - the transmission (4) of the measurement signals and of positions detected for viewing (in general, by conventional serial transmission line of logic signals); - the transmission (3) of the position signal (s) detected for the regulation devices (in general, by conventional line of regulation signals: analog current or voltage output signals). 3. The terminal (6) comprising a display device (video monitor) which collects the transmitted measurements. The visualization is carried out by making appear on an image comprising a coordinate of dimension (height of the container, for example) and a coordinate of relative concentration, the transmitted measurements. Points are thus obtained corresponding to a curve representative of the state of relative concentration of the contents of the container. Depending on the application, various types of representation can be used.
