Abstract

The turbine has a flow straightener integrated into a housing of the turbine, where the flow straightener has a honeycomb structure. A diameter of the honeycomb is in the range of 1.2 mm to 1.8 mm, and a length of the honeycomb is in the range of 19 mm to 19.5 mm.

Description

Turbinen werden eingesetzt um Flüssigkeiten und Gase zu messen. Das Messprinzip beruht auf einem drehenden Rotor, dessen Rotationsgeschwindigkeit über einen Aufnehmer abgegriffen wird, und die gemessenen Pulse in ein entsprechendes Signal umgesetzt werden.turbines are used for liquids and to measure gases. The measuring principle is based on a rotating rotor, its rotational speed over a pickup is tapped, and the measured pulses into a corresponding signal to be implemented.

Stand der Technik ist es, dass, um ein gleichförmiges Strömungsprofil am Rotor zu erhalten, Einlaufstrecken vor den eigentlichen Durchflussmesser zu installieren. Hiermit soll das gleichförmige Strömungsprofil erreicht werden. Eine übliche Länge der Einlaufstrecke beträgt 10x bis 20x Durchmesser der Rohrleitung. Es ist auch Stand der Technik die Länge der Einlaufstrecke dadurch zu verkürzen, indem Strömungsgleichrichter in die Einlaufstrecken zu integrieren.was standing the technique is that in order to obtain a uniform flow profile on the rotor, Installing inlet sections before the actual flow meter. Hereby is the uniform flow profile be achieved. A usual Length of the inlet section is 10x to 20x diameter of the pipeline. It is also state of the art the length of the To shorten the inlet section thereby by flow rectifier to integrate into the inlet sections.

Der im Patentanspruch 1 abgegebenen Erfindung liegt das Problem zugrunde, dass viele Anwendungen und Einbauorte eine Einlaufstrecke aus Platzgründen nicht zulassen. Als Beispiel sei hier der Motorraum eines Kraftfahrzeuges genannt. Bei einer angenommenen Rohrleitung von 6 mm würde man eine Einlaufstrecke von mindestens 60 mm vor der Messturbine benötigen. Bei der Enge in den heutigen Motorräumen ist dies nicht realisierbar.Of the The invention provided in claim 1 is based on the problem that many applications and installation locations an inlet section for reasons of space not allow. As an example, here is the engine compartment of a motor vehicle called. Assuming a pipeline of 6 mm would be a Inlet distance of at least 60 mm in front of the measuring turbine. at the narrowness in today's engine compartments this is not feasible.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This Problem is solved by the features listed in claim 1 solved.

Durch die Verwendung des im Patentanspruchs beschriebenen Systems kann auf die Einlaufstrecken verzichtet werden, ohne eine Verminderung der Messgenauigkeit in Kauf nehmen zu müssen.By the use of the system described in the claim can to dispense with the inlet sections, without a reduction to accept the accuracy of measurement.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 3 angegeben.A advantageous embodiment of the invention is in claim 3 specified.

Die Kombination der in Patentanspruch 3 angegebenen Masse haben sich in Tests als besonders geeignet erwiesen, um eine optimiertes Verhältnis zwischen Baulänge und Wabendurchmessers des Strömungsgleichrichters bei optimierter Leistungsfähigkeit zu erreichen (1 + 2).The combination of the mass specified in claim 3 have been found in tests to be particularly suitable to achieve an optimized ratio between overall length and honeycomb diameter of the flow straightener with optimized performance ( 1 + 2 ).
