Description

Strömungsmesser mit beweglichem Staukörper. Die Erfindung betrifft den bekannten Strömungsmesser mit einem unter der Wirkung einer Gegenkraft sich infolge des Strömungsdruckes verschiebenden Staukörper, der sich insbesondere für verunreinigte oder zur Kristallisation neigende Medien gut eignet. Gemäß der Erfindung wird die Verschiebungsgröße dadurch elektrisch angezeigt, daß im Innern des Staukörpers ein elektrischer Kondensator so angebracht ist, daß sich der Plattenabstand entsprechend ändert. Die jeweilige Kapazität ist dann ein Maß für die Verschiebung des Staukörpers und damit für die Geschwindigkeit. Bemerkt wird hierzu, daß düs Messen von Verschiebungsgrößen mittels eines Kondensators an sich nicht neu ist. Auf der Zeichnung ist ein Ausführungsbeispiel dargestellt.Flow meter with movable bluff body. The invention relates to the well-known flow meter with one under the action of a counterforce itself due to the flow pressure shifting bluff body, which is particularly suitable for Contaminated media or media that tend to crystallize are well suited. According to the invention the amount of displacement is indicated electrically by the fact that inside the bluff body an electrical capacitor is attached so that the plate spacing is accordingly changes. The respective capacity is then a measure of the displacement of the bluff body and thus for the speed. It should be noted that the measurement of displacement quantities by means of a capacitor is in itself not new. An exemplary embodiment is shown in the drawing shown.

In dem strömenden Medium befindet sich ein Körper A, der als Schwimmkörper ausgebildet ist und zweckmäßig Stromlinienform erhält, Die ihm durch das strömende 1Zedium übermittelte Bewegungsenergie wird auf einer. elektrischen Kondensator B übertragen, dessen eine Platte 1I durch den Bügel C starr mit dein Strombett D des Mediums und dessen andere Platte I mit dem Staukörper verbunden ist. Eine durch den Körper H mit dem Bügel C starr verbundene Feder G oder ein Federrohr o. dgl. bildet die Gegenkraft gegen den Strömungsdruck. Bei einer Verschiebung des Staukörpers infolge des verändert sich die Kapazität des Kondensators, die in geeigneter Weise gemessen werden kann und ein Maß der jeweiligen Ströniungsgeschwindigkeit ist.In the flowing medium there is a body A, which acts as a floating body is designed and appropriately streamlined, which gives it through the flowing 1Zedium transmitted kinetic energy is transferred to a. electrical capacitor B transferred, whose one plate 1I through the bracket C rigidly with your stream bed D of the Medium and the other plate I is connected to the bluff body. One through the body H with the bracket C rigidly connected spring G or a spring tube o. forms the counterforce against the flow pressure. In the event of a displacement of the bluff body as a result, the capacitance of the capacitor changes in a suitable manner can be measured and is a measure of the respective flow rate.

Zur Erhöhung der Geschwindigkeit -des strömenden Mediums und des daraus sich ergebenden Druckes auf den Meßkörper kann das Strombett an der. l@Ießstelle düsenartig verengt werden.To increase the speed of the flowing medium and that of it resulting pressure on the measuring body can the stream bed on the. l @ Ießstelle be narrowed like a nozzle.
