Description

Strömungsmesser mit Teiistrommessung. Die Erfindung betrifft eine Vorrichtung für Dampf-, Gas- oder Flüssigkeitsmessungen, mit welcher von der gesamten DurchfluB-menge ein -genau bestimmter Bruchteil gemessen werden kann. Die neue Vorrichtung arbeitet nach dem bekannten Grundsatz der Drosselung in Haupt- und Nebenstrom, wobei die Drosseldrücke auf ein Flüssigkeitswaagensystem übertragen werden, welches durch mit ihm verbundene Schieberorgane den Durchfiuß regelt. Die bekannten Vorichtungen dieser Art haben den Nachteil, daß zur Übertragung der Drücke bewegliche -Leitungen oder Stopfbüchsen notwendig sind, wodurch die Erreichung de -zur genauen Regelung unbedingt erforderlichen indifferenten Gleichgewichtes des Waagensystems sehr erschwert, wenn nicht gar verhindert wird. Die nachstehend beschriebene Einrichtung vermeidet die Nachteile dadurch, daß das Waagensystem im Innern der Gasströme angebracht ist.Flow meter with partial flow measurement. The invention relates to a Device for vapor, gas or liquid measurements, with whichever of the whole Flow rate a precisely determined fraction can be measured. The new device works according to the well-known principle of throttling in main and secondary flow, whereby the throttle pressures are transmitted to a liquid balance system, which through valve organs connected to it regulate the flow. The known devices of this type have the disadvantage that movable to transmit the pressures -Pipes or stuffing boxes are necessary, thereby achieving de -for accurate Regulation of the indifferent equilibrium of the balance system that is absolutely necessary very difficult, if not prevented at all. The setup described below avoids the disadvantages in that the balance system is mounted inside the gas streams is.

Gemäß Abbildung sitzen auf dem Waagebalken x die zweckentsprechend geformten Gefäße g, .bis g4 derart befestigt, daß für das Waagensystem indifferentes Gleichgewicht besteht. Das Gefäß g, befindet sich im allseitig geschlossenes und mit dem gleichfalls geschlossenen Raum K2 durch die Öffnung OZ verbundenen Raum Kg, die Gefäße g2 und g$ in dem mit der Leitung A verbundenen Raum K" g, in dem gleichfalls mit der Leitung verbundenen Raum K,. In der Leitung sitzt noch ein fester Widerstand w, welcher auch gegebenenfalls von dem Waagensystem betätigt werden kann. Die Gefäße g, und g2 sind durch eine festliegende Heberleitung hl, die Gefäße g8 und g4 durch die Heberleitung h2 derart miteinander verbunden, saß die Flüssigkeiten in ihnen hin und her fließen können. Unterhalb ihrer Ausflußöffnungen sind mit den Leitungen fest verbundene Prallplatten p vorgesehen, um bei stoßweisem Fließen Stoßwirkungen auf das Waagensystem zu verhüten.As shown in the figure, they sit appropriately on the balance beam x shaped vessels g, .to g4 attached in such a way that indifferent for the balance system Balance exists. The vessel g is located in the closed on all sides and with the likewise closed space K2 through the opening OZ connected space Kg, the vessels g2 and g $ in the space K "g connected to the line A, in which room K, also connected to the line. There is another one on the line Resistance w, which can also be actuated by the balance system if necessary. The vessels g, and g2 are connected by a fixed siphon line hl, the vessels g8 and g4 connected to each other by the siphon line h2 so sat the liquids can flow back and forth in them. Below their outflow openings are with the Lines firmly connected baffle plates p are provided to avoid impact effects in the case of intermittent flow to prevent the balance system.

Das Gas strömt als Teilstrom von der Stelle vor dem Drosselflansch durch Leitung A, Raum K2, Öffnung 02, Raum Kg, Schieberöffnung O9, Leitung B, Messer m, Leitung i zur Stelle hinter dem Drosselflansch. Vergrößert sich nun z. B. der Widerstand im Messer w, wodurch der Druck im Raum Kg steigt, so tritt Flüssigkeit von g, nach g2, das Waagensystem dreht sich nach links und vergrößert dadurch die Öffnung 0s mittels des mit dem Waagensystem fest verbundenen Schiebers s, und zwar so weit, bis der vergrößerte Widerstand im Messer durch Verkleinerung des Widerstandes an der Öffnung 03 ausgeglichen ist.The gas flows as a partial flow from the point in front of the throttle flange through line A, space K2, opening 02, space Kg, slide opening O9, line B, knife m, line i to the point behind the throttle flange. Now z. B. the resistance in knife w, which increases the pressure in space Kg, then liquid flows from g to g2, the balance system rotates to the left and thereby enlarges the opening 0s by means of the slide s firmly connected to the balance system, as follows until the increased resistance in the knife is compensated for by reducing the resistance at opening 03.
