Patentiert im Deutschen Reiche vom 21. Juni 1913 ab.Patented in the German Empire on June 21, 1913.

Die Erfindung besteht darin, daß zur Feststellung von Flüssigkeits- und Gasmengen durch Messung der Strömungsenergie bekannte Einrichtungen, die für Gasmengenmessungen in Benutzung sind, derart gebraucht werden, daß der Verbindungsleitung zwischen Meßgerät und Anzeige- oder Registriervorrichtung fortdauernd Druckluft zugeführt wird, die an der Meßstelle aus dem Meßgerät dauernd oderThe invention consists in that to determine the amount of liquid and gas devices known by measuring the flow energy, which are used for gas quantity measurements are in use, are used in such a way that the connecting line between the measuring device and the display or registration device is continuously supplied with compressed air connected to the measuring point from the measuring device continuously or

ίο zeitweise austritt. In den Verbindungsleitungen zum Apparat ist also ein Druck vorhanden, der dem statischen Druck an der Meßstelle plus dem dynamischen Druck entspricht. Die Differenz dieser beiden Drucke, die in bekannter Weise durch ein Differentialmanometer gemessen wird, ist dann ein Maß für die Strömungsenergie und die Geschwindigkeit.ίο temporarily emerges. In the connecting lines there is therefore a pressure on the apparatus that corresponds to the static pressure at the measuring point plus corresponds to the dynamic pressure. The difference between these two prints, which is known in Way is measured by a differential manometer, is then a measure of the flow energy and the speed.

In der Zeichnung ist ein Beispiel dargestellt. In Rohr i sind zwei rechtwinklig gekrümmte Rohre f eingebaut, die mit und gegen den Strom gerichtet sind. Durch die beiden Verbindungsrohre g sind diese beiden Rohre f mit dem Differentialmanometer h verbunden. Andererseits stehen sie durch die Leitungen β mit den beiden Wassertrommelgebläsen a in Verbindung. Bei den Wassertrommelgebläsen tritt bei b das unter Druck stehende Triebwasser ein.An example is shown in the drawing. Two tubes f curved at right angles are installed in tube i , which are directed with and against the flow. These two pipes f are connected to the differential manometer h by the two connecting pipes g . On the other hand, they are connected to the two water drum fans a through the lines β . In the case of the water drum blowers, the pressurized headwater enters at b.

Das Triebwasser umspült die Erweiterung des Rohres c. Diese Erweiterung ist am Umfange mit Öffnungen m versehen. Durch das mit großer Geschwindigkeit an der Erweiterung des Rohres c vorbeiströmende Wasser wird durch die Öffnungen m und Rohr c Luft angesaugt, durch das enge Rohr 0 hindurch mitgerissen und in das weite Rohr d abgeschieden, während das Triebwasser durch Rohr q austritt. In d steht die Luft unter einem Druck, der der Höhe q des Austrittsrohres entspricht. Durch Rohr e gelangt die Luft nach f und tritt hier dauernd aus. Durch diese Einrichtung ist in den Zuleitungen g zum Apparat h lediglich Luft enthalten und die Messung der Geschwindigkeit des Flüssigkeitsstromes kann in gleicher Weise erfolgen, wie sie sonst für Luftmessungen in Gebrauch ist. Weiter hat diese Einrichtung den Vorteil, daß das Registrierinstrument in beliebiger Entfernung vom Meßgerät aufgestellt werden kann. Außerdem ist die Methode geeignet zur Messung von Laugen und säurehaltigen Flüssigkeiten, die ohne Anwendung dieser Methode das Material der Meßvorrichtung zerstören würden. Brauchbar ist die Methode fernerhin zur Messung von säurehaltigen Gasen, ,,bei denen auf diese Art und Weise ein Eintritt der zerstörenden Gase in die Apparatur vermieden wird.The headwater washes around the extension of the pipe c. This extension is provided with openings m on the circumference. The water flowing past the widening of pipe c at high speed sucks in air through the openings m and pipe c, entrains it through the narrow pipe 0 and separates it into the wide pipe d , while the driving water exits through pipe q. In d the air is under a pressure which corresponds to the height q of the outlet pipe. The air passes through tube e to f and exits here continuously. As a result of this device, only air is contained in the feed lines g to the apparatus h and the measurement of the velocity of the liquid flow can be carried out in the same way as is otherwise used for air measurements. This device also has the advantage that the recording instrument can be set up at any distance from the measuring device. In addition, the method is suitable for measuring alkalis and acidic liquids, which would destroy the material of the measuring device without using this method. The method can also be used for the measurement of acidic gases, in which the entry of the destructive gases into the apparatus is avoided in this way.
