Description
Vorrichtung zur Messung der Durchflußmenge von strömenden Flüssigkeiten und Gasen mit einem in einem verengten Durchflußrohr beweglichen Meßkörper. Die Erfindung ist auf eine Vorrichtung zur Messung der Durchflußmenge von strömenden Flüssigkeiten und Gasen mit einem in einem verengten Durchflußrohr beweglichen Meßkörper gerichtet. Sie besteht darin, daß der Meßkörper gegen eine Feder beweglich und der Durchflußquerschnitt so veränderlich ist, daß bei `jeder Stellung des Meßkörpers die Durchflußmenge dem durch einen Druckmesser angezeigten Druckunterschied vor und- hinter dem Meßkörper proportional ist. Auf diese Weise wird eine Unabhängigkeit des Aufstellungsortes der Anzeigevorrichtung von der Meßstelle und zugleich eine Proportionalität der Ausschläge der Anzeigevorrichtung erreicht.Device for measuring the flow rate of flowing liquids and gases with a measuring body movable in a narrowed flow tube. the Invention is to a device for measuring the flow rate of flowing Liquids and gases with a measuring body movable in a narrowed flow tube directed. It consists in the fact that the measuring body is movable against a spring and the The flow cross-section is so variable that in every position of the measuring body the flow rate before the pressure difference indicated by a pressure gauge and- is proportional behind the measuring body. In this way it becomes an independence the place of installation of the display device from the measuring point and at the same time a Reached proportionality of the deflections of the display device.
In der Abbildung ist ein Ausführungsbeispiel der neuen Meßvorrichtung dargestellt: Das Medium gelangt, wie beim Venturi-Messer, beim Austritt von dem Raum a in den Raum b durch eine Einschnürung. In die engste Stelle dieser Einschnürung ist ein Kegel oder eine Scheibe c lose so eingepaßt, daß er den Durchflußquerschnitt abschließt. In dieser Lage befindet sich der geführte und an einer Feder d hängende Kegel, wenn kein Durchfluß stattfiudet. Beim Durchfluß muß der Kegel c der Durchflußmenge entsprechend sich heben. Die Form des nach oben sich erweiternden Raumes b und die Feder d sind so zueinander abgestimmt, daß die Druckunterschiede vor und hinter dem Kegel proportional sind den jeweiligen Durchflußmengen. Die Leitungen für die Anzeigevorrichtung sind an den beiden Stellen e und f angeschlossen.In the figure, an embodiment of the new measuring device is shown: As with the Venturi knife, the medium passes through a constriction when it exits from space a into space b. In the narrowest point of this constriction, a cone or a disk c is loosely fitted so that it closes off the flow cross-section. The cone, which is guided and suspended from a spring d, is in this position when there is no flow. When there is a flow, the cone c must rise according to the flow rate. The shape of the upwardly expanding space b and the spring d are matched to one another in such a way that the pressure differences in front of and behind the cone are proportional to the respective flow rates. The lines for the display device are connected at the two points e and f.
