Description

blornentmesser in Nebenschlußanordnung zur INIes ng der Strömungsgeschwindigkeit von Gasen*'und Flüssigkeiten in Rohrleitungen von verschiedenem Durchmesser. Die Erfindung stellt einen Momentmesser dar, der ähnlich der Pitotschen Röhre im Nebenschluß an Leitungen verschiedenen Durchinessers angeschaltet werden, kann zwecks Feststellung der durchstrOtnenden Menge. Die konische Meßröhze ist zwecks Einführung in die Leitung nach unten rohrförmig verlängert und trägt am Ende des Rohres eine Stauschefbe, die nach Einführung des Instrumentes in die Hauptleitung den Druck in ider letzteren staut. In der Stauscheibe befindet sich eine kleine Öffnung, die !durch den Rohrfortsatz mit idem konischen Meßrohr in Verbindung steht. Da nun der Momentmesser an sich bei hohem und tiefem Schwimmerstand praktisch einen gleichbleibenden Druckvert-ust hat, so wird der Schwimmerstand in -diesem Falle bestimmt -durch die Höhe ides vor ;der Stauscheibe herrschenden Druckes. Es ist somit der jeweilige Schwimnierstand ein Maß für den vor der Stauscheibe herrschenden Druck, und letzterer kann auf der Skala ablesbar gemacht werden. Hierdurch wird (die Anzeige des Instrumentes innerhalb praktischer Grenzen unabhängig von dem Durchmesser ider Hauptleitung und kann in Leitungen verschiedenen Durchmessers zur Messung (des darin vorhandenen Strömungsdruckes,und somit zur Bestimmung der durchströmenden Mengen dienen.Bleed meter in shunt arrangement for INIes ng the flow velocity of gases * 'and liquids in pipes of various diameters. the Invention represents a moment meter which is similar to the Pitot tube in the shunt can be connected to lines of different diameters for the purpose of determining the flowing crowd. The conical measuring tube is for the purpose of insertion into the pipe extended downwards in the shape of a tube and has a retaining flask at the end of the tube, which after the introduction of the instrument into the main line reduces the pressure in the latter jams. In the baffle there is a small opening that! Through the pipe extension is in communication with the conical measuring tube. Now there is the moment meter itself With a high and low float level, there is practically a constant loss of pressure in this case, the level of the swimmer is determined by the height ides the pressure prevailing in the baffle. It is therefore the respective swimming stand a measure of the pressure prevailing in front of the baffle plate, and the latter can be measured on the Scale can be made readable. This (the display of the instrument within practical limits regardless of the diameter of the main line and can be in Lines of various diameters for measuring (the flow pressure present in them, and thus serve to determine the quantities flowing through.

Die Zeichnung stellt einen Nebenschlußmesser in der durch die Erfindung gekennzeichneten Artdar. In der Hauptleitung befindet sich die Stauscheibe a, die in der Mitte eine Öffnung b trägt. An diese öffnung schließt sich ein erweitertes Rohr c, das nach außen zum Momentmesser d führt und von dort gleichfalls in - derselben Weise in die Hauptleitungzurfück. Der vor der Stauscheibea herrschende Druck treibt ein gewisses Quantum Gas oder.Flüssigkeitdurch den Momentmesser, dessen Schwimmer sich diesem Druck entsprechend einstellt, und zwar ist,die Größe der Scheibe a und (der Öffnung b so gewählt, daß bei geringstem Durchlaß durch die Hauptleitung (der ##chwimmer unten, beim Höchst'durchlaß oben steht.-.- Der Schwimmer zeigt also idurch seine Höhenlage die vor der Stauscheibea herrschenden Drucke an und gibt dementsprechend ein ' M, aß für -den -je-#veiligen Durchlaß. Der Momentmesser d, mit der zugehörigen- Stauscheibea und den' Leitungen kann nun aus der Hauptleitung entfernt und in derselben Weise zur Messung ,des Staudruckes in anderen Leitungen benutzt werden, ähnlich der Pitotschen, Röhre.The drawing shows a shunt knife of the type characterized by the invention. In the main line is the baffle plate a, which has an opening b in the middle. At this opening is an expanded tube includes c, d the outside leads to the torque meter and from there likewise in - the same manner in the Hauptleitungzurfück. The pressure prevailing in front of the baffle a drives a certain amount of gas or liquid through the torque meter, the float of which is adjusted according to this pressure, namely the size of the disc a and (the opening b selected so that with the smallest passage through the main line ( the ## swimmer is at the bottom, at the highest 'passage at the top.-.- The height of the swimmer shows the pressures prevailing in front of the baffle a and accordingly gives an ' M, ate for -the -e- # veilige passage d, with the associated baffle a and the 'lines can now be removed from the main line and used in the same way to measure the dynamic pressure in other lines, similar to the Pitot tube.
