Description

Meßrohr für Schwimmerströmungsmesser Es sind Meßrohre für Schwimmerströmungsmesser bekannt, die konisch verlaufen, aber drei oder mehrere schmale, nach innen vorspringende, sich axial erstreckende Schwimmerführungsrippen besitzen, die geradlinig von der engsten Stelle des Meßrohres von unten nach oben verlaufen und mit ihren Kanten einen Zylinder umschließen, dessen Durchmesser dem Durchmesser der engsten Stelle des Meßrohres entspricht, so daß sie den anzeigenden Meßschwimmer bzw. Schwebekörper in allen Lagen stützen und Schwingungen desselben verhindern.Measuring tube for float flow meter These are measuring tubes for float flow meters known, which are conical, but three or more narrow, inwardly protruding, have axially extending float guide ribs straight from the narrowest point of the measuring tube from bottom to top and with their edges enclose a cylinder, the diameter of which corresponds to the diameter of the narrowest point of the measuring tube, so that it corresponds to the indicating measuring float or float Support in all positions and prevent vibrations.

Diese axial und geradlinig angeordneten Führungsrippen haben den Nachteil, daß der Schwebekörper sie stets an der gleichen Stelle berührt und daß an diesen Stellen unter Umständen kleine Vertiefungen oder Rillen entstehen, wodurch die Meßgenauigkeit stark beeinträchtigt wird. These axially and rectilinearly arranged guide ribs have the Disadvantage that the float always touches them in the same place and that in these places small pits or grooves may appear, which the measurement accuracy is severely impaired.

Die vorliegende Erfindung schließt diesen Nachteil aus, indem sie die Führungsrippen im Meßkonus spiralförmig anordnet, wobei diese Spiralen koaxial zur Konusachse verlaufen. The present invention eliminates this disadvantage by the guide ribs are arranged in a spiral shape in the measuring cone, these spirals being coaxial run to the cone axis.

In der Abbildung ist ein Meßrohr in einer beispielsweisen Form dargestellt, wobei 1 das konisch verlaufende Meßrohr und 2 die spiralförmigen Führungsrippen darstellt. In the figure, a measuring tube is shown in an exemplary form, where 1 is the conical measuring tube and 2 is the spiral guide ribs represents.
