Description

Verfahren zur rdengenmessung von Dampf oder beißen Gasen in Rohrleitungen. Das vorliegende Verfahren bezweckt die Mengenmessung von Dampf oder heißen Gasen in Rohrleitungen dadurch, daß der Dampf oder das Gas einer thermodynamischen Zustandsänderung unterworfen wird und die dabei auftretenden Temperaturänderungen gemessen werden.Method for measuring the volume of steam or biting gases in pipelines. The purpose of the present method is to measure the amount of steam or hot gases in pipelines in that the steam or gas undergoes a thermodynamic change of state is subjected and the temperature changes that occur are measured.

Aus den Gesetzen der Thermodynamik folgt, daß die Zustandsänderungenwströmender Gase oder Dämpfe und somit- die dabei auftretenden Temperaturänderungen merklich von der Ströinungsgeschwindigkeit vor der Zustandsände-@ rung abhängen. Es ist somit möglich, aus dieser Temperaturänderung auf die Strömungsgesrhwindigkeit vor der Zustandsänderung zu schließen. Auf dieser Erkenntnis beruht die vorliegende. Erfindung.From the laws of thermodynamics it follows that the changes of state are more flowing Gases or vapors and thus the temperature changes that occur are noticeable depend on the flow velocity before the change of state. So it is possible, from this temperature change on the flow rate before the Close change of state. The present one is based on this knowledge. Invention.

Fig. i stellt einen Adiabatendampfmesser dar. Der strömende Dampf wird zunächst in einer wärmegeschützten Düse einer adiabatischen Kompression unterworfen, wobei die dabei auftretende Temperaturdifferenz durch ein Thermoelement gemessen wird. In einem anschließenden Diffusor wird der Dampf wieder angenähert auf die. Anfangsverhältnisse gebracht.Fig. I shows an adiabatic steam meter. The flowing steam is first subjected to adiabatic compression in a heat-protected nozzle, the temperature difference occurring thereby being measured by a thermocouple will. In a subsequent diffuser, the steam is again approximated to the. Initial conditions brought.

Fig. z stellt einen Drosseldampfmesser dar. Hierbei läßt sich allerdings ein Druckabfall nicht vermeiden. - Im übrigen entspricht das Verfahren den obigen Ausführungen.Fig. Z shows a throttle vapor meter do not avoid a pressure drop. - Otherwise the procedure is the same as above Executions.

In der Zeichnung ist angenommen, daß die eine Lötstelle des Thermoelementes vor-, die andere in der Zustandsänderung liegt. Man kann natürlich auch die Messung beider Temperaturen und die Feststellung der Temperaturdifferenz .durch zwei verschiedene Thermoelemente vornehmen, wobei man gleichzeitig aus den Angaben des ersten Thermoelementes den Dampfzustand (Druck, Temperatur) ' feststellen kann. Auch eine Vereinigung beider Thermoelemente ist möglich, derart, daß man unmittelbar aus den Angaben der Thermoelemente die durchgegangenen Wärmeeinheiten ersehen kann. Man braucht auch nicht die Thermoelemente, wie in der Zeichnung angenommen wurde, mitten in den strömenden Stoff hinein zu legen, sondern kann sie in die Wandung der Leitung einbetten; denn die dort auftretende Temperatur steht stets in einem bestimmten Verhältnis zu der Temperatur des strömenden Stoffes.In the drawing it is assumed that the one soldering point of the thermocouple before, the other is in the change of state. You can of course also take the measurement both temperatures and the determination of the temperature difference .by two different Make thermocouples, at the same time referring to the details of the first thermocouple the state of vapor (pressure, temperature) 'can determine. Also a union of both Thermocouples are possible in such a way that one can immediately read the information on the thermocouples can see the thermal units passed through. You don't need the thermocouples either, as was assumed in the drawing, into the middle of the flowing material place, but can embed them in the wall of the line; because the one occurring there Temperature is always related to the temperature of the flowing Substance.

Natürlich können außer Thermoelementen auch alle anderen Einrichtungen zur Messung von Temperaturen benutzt werden. Für die Aufzeichnung und Auswertung der Temperaturmessungen können alle für solche Zwecke üblichen Methoden benutzt werden.Of course, apart from thermocouples, all other devices can also be used can be used to measure temperatures. For recording and evaluation All methods customary for such purposes can be used for temperature measurements will.
