Title (EN) DEVICE FOR MEASURING THE AMOUNT FLOWING THROUGH AND/OR THE SPEED OF FLOW OF A MEDIUM
(FR) DISPOSITIF DE MESURE DE LA QUANTITE ET/OU LA VITESSE D"ECOULEMENT D"UN MILIEU
Abstract: front page image
(EN)A device for measuring the amount flowing through and/or the speed of flow of a medium which is pumped by means of a pump unit. The device comprises a drive motor for producing the working cycles of the pump unit and a pick-off to detect said working cycles and to deliver a pick-off signal depending on said working cycles. Further included is an electronic unit (10) to record, by means of said pick-off signal, a value proportional to the number of working cycles. From this value, the amount flowing through and/or the speed of flow can be determined by means of a nominal calibrating factor KN laid down for the pump unit. The electronic unit (10) includes a calibrating unit (11) which is adjustable to convert said pick-off signal into at least one output signal which represents a certain true calibrating factor KV, calculated with reference to a specific correction factor KK, for correction of the nominal calibrating factor KN. Further included are devices (12 - 15) for recording the amount and/or speed of flow of the medium flowing through, adapted to be controlled by the output signal from the calibrating unit.
(FR)Dispositif de mesure de la quantite et/ou de la vitesse d"ecoulement d"un milieu pompe a l"aide d"une pompe. Le dispositif comprend un moteur d"entrainement pour produire des cycles de travail de la pompe et d"un capteur pour detecter ces cycles de travail et envoyer un signal de detection en fonction de ces cycles de travail. Une unite electronique (10) est prevue pour enregistrer a l"aide de ces signaux de detection une valeur proportionnelle au nombre de cycles de travail. A partir de cette valeur, la quantite de milieu s"ecoulant et/ou la vitesse d"ecoulement peut etre determinee a l"aide d"un facteur de calibrage nominal KN etabli pour la pompe. L"unite electronique (10) comprend une unite de calibrage (11) qui est ajustable pour convertir ce signal de detection en au moins un signal de sortie qui represente un facteur de calibrage reel KV calcule en reference a un facteur de correction specifique KK pour la correction du facteur de calibrage nominal KN. Des dispositifs (12-15) sont egalement prevus pour enregistrer la quantite et/ou la vitesse d"ecoulement du milieu, lesquelles sont adaptees pour etre commandees par le signal de sortie provenant de l"unite de calibrage.
