Description

Die Erfindung betrifft ein Verfahren zum Bestimmen strömender Dämpfe od. dgl. durch Differenzdruckmessung und eine zur Durchführung des Verfahrens bergerichtere Vorrichtung. The invention relates to a method for determining flowing vapors od. The like. By differential pressure measurement and a bergerichtere to carry out the method Contraption.

Beim Messen strömender Mittel, die zur Kondensierung neigen, ergibt sich bekanntlich die Schwierigkeit, daß das Kondensat die Messung beeinflußt. Erfindungsgemäß wird nun diese Fälschung des Neßergebnisses zielbewußt in dem Sinne ausgenutzt, daß das Kondensat selber zum Betrieb eines Differenzdruckmessers verwandt wird, soX daß also der Umstand der kondensarbildung das Meßergebnis nicht mehr nach Plus oder Minus bleeinflussen kann. Zur Durchführung des Verfahrens wird lals Differenzdruckm.esser insbesondere ein Strömungsmesser in Vorschlag gebracht, der erfin dungsgemäß vom strömenden Kondensat betrieben wird, wobei als Motor des strömenden Kondensats eben der Differenzdruck dient. Um eine Dauerablesung zu ermöglichen, sieht die Erfindung außerdem vor, das sich infolge des Differenzdrucks blewiegende Kondensat nicht im Kreislauf zu führen, sendern z. B. in die Hauptleitung frei ablaufen zu lassen lund durch im Überschuß gebildetes, gegebenenfalls aus der Hauptleitung abgezogenes Kondensat zu ergänzen. When measuring flowing means that tend to condense, gives As is well known, the difficulty arises that the condensate affects the measurement. According to the invention this falsification of the test result is now purposefully exploited in the sense that that the condensate itself is used to operate a differential pressure meter, so that the fact of the formation of condensate no longer changes the measurement result to plus or minus bleeding. A differential pressure meter is used to carry out the procedure in particular brought a flow meter in the proposal, the inventions according to the flowing condensate is operated, with just as the motor of the flowing condensate the differential pressure is used. To enable continuous reading, the invention provides In addition, the condensate, which weighs in due to the differential pressure, is not in the To lead cycle, send z. B. to run freely in the main line lund by condensate formed in excess and possibly withdrawn from the main line to complete.

In Ider Zeichnung ist die Erfindung beispielsweise dargestellt. In the drawing, the invention is shown by way of example.

In einer Leitung 1 für das strömende Mittel ist eine Blende 2 vorgesehen. Vor und hinter der Blende befinden sich Leitungen 3 und 4, über welche ein Teil des strömenden Mittels über einen Differenzdruckmesser in an sich bekannter Weise geführt wird. Als Differenzdruckmesser ist ein Strömungsmesser 5 vorgesehen, bestehend aus einem konischen Rohr, in dem ein Schwimmer 6 spielt. A screen 2 is provided in a line 1 for the flowing medium. In front of and behind the panel there are lines 3 and 4, over which a part of the flowing medium via a differential pressure meter in a manner known per se to be led. A flow meter 5 is provided as a differential pressure meter, consisting from a conical tube in which a swimmer 6 plays.

Des weiteren ist eine Abzugsleitung 7 vorgesehen, die über einen Kondensator 8 in die Leitung 4 mündet.Furthermore, a discharge line 7 is provided, which is connected to a condenser 8 opens into line 4.

Die Wirkungsweise der Vorrichtung ist folgende: Ein Teil des strömenden Dampfes kondensiert alsbald bei Inbetriebnahme in der Nebenleitung und füllt den Differenzdruckmesser. Infolge der Druckdifferenz zwischen den Leitungen 3 und 4 beginnt im Strömungsmesser eine den Schwimmer ins Spiel bringende Strömung, wobei da,s strömende Kondensat über die Leitung 3 wieder zur Hauptleitung 1 zurückfließt Gleichzeitig aber bildet sich im Kondensator 8 überflüssiges Kondensat, das für Ersatz des abströmenden Kondensats sorgt, wobei der Überschuß zur Hauptleitung I über den oberen Teil des Rohres 4 abfließt, Gegebenenfalls kann man dem Kondensator 8 einen besonderen Behälter mit Kondensator zuordnen, aus dem durch Regelung der Zuflußmenge der erforderliche Überschuß zeitweilig oder für die Dauer sichergestellt wird. The mode of operation of the device is as follows: Part of the flowing Steam condenses in the secondary line as soon as it is started up and fills the Differential pressure meter. As a result of the pressure difference between lines 3 and 4 a current that brings the swimmer into play begins in the flow meter, whereby since, s flowing condensate flows back to main line 1 via line 3 At the same time, however, forms superfluous condensate in the condenser 8, which is for Replacement of the outflowing condensate ensures, with the excess to the main line I flows through the upper part of the pipe 4, if necessary, you can use the condenser 8 assign a special container with a condenser, from which the Inflow the required excess temporarily or permanently ensured will.
