Description

Verfahren und Vorrichtung zum Messen der Geschwindigkeit und der )Menge strömender Gase und Dämpfe Den Gegenstand der vorliegenden Erfindung bildet ein Verfahrp und eine Vorrichtung zum Messen der Strömungsgeschwindigkeit und der Menge strömender Medien in Dampf- oder Gasform.Method and device for measuring speed and amount flowing gases and vapors The subject of the present invention forms a Verfahrp and a device for measuring the flow velocity and the amount flowing media in vapor or gas form.

Die vorliegende Erfindung basiert auf der Abhängigkeit der Wanderungsgeschwindigkeit von Gasionen von der Strömungsgeschwindigkeit des Gases. Ordnet man in dem Gase zwei Elektroden an, an die über einen Strommesser hinweg ein konstantes Leitungspotential angelegt wird, so findet bei einer Ionisation der Gasstrecke zwischen den Elektroden durch einen Ionisator ein als unselbständige Entladung bezeichneter Stromübergang zwischen den Elektroden statt. Dieser Strom ist abhängig von der Geschwindigkeit des Mediums, und das Meßinstrument zeigt die Geschwindigkeit oder die Menge des Mediums an.The present invention is based on the migration speed dependency of gas ions from the flow velocity of the gas. One arranges in the gases two electrodes to which a constant line potential across an ammeter is applied, then takes place in an ionization of the gas path between the electrodes by an ionizer, a current transfer referred to as a dependent discharge between the electrodes. This current depends on the speed of the medium, and the measuring instrument shows the speed or the amount of Medium.

Auf der beiliegenden Zeichnung ist in Abb. i eine schematische Darstellung der Vorrichtung gegeben, in Abb.2 eine veränderte Ausführungsform.On the accompanying drawing is a schematic representation in Fig. I given the device, in Fig.2 a modified embodiment.

In dem Rohre c befindet sich ein Kaliberrohr b, welches einen aliquoten Teil des strömenden Mediums aufnimmt. Innerhalb dieses Kaliberrohres b befinden sich zwei Elektroden a1 und a2, die vorteilhaft als Gitterelektroden ausgebildet sind. Diese Elektrodental und a2 sind über ein Strommeßgerät an eine konstante Spannung angelegt. Das Meßinstrument, die Spannungsquelle und ein evtl. vorgeschalteter Apparat zur Konstanthaltung der Meßspannung sind nicht dargestellt. Zwischen den Elektroden befindet sich ein Ionisa.tor, der aber ebenfalls nicht zeichnerisch da?gestellt ist.In the tube c there is a caliber tube b, which has an aliquot Absorbs part of the flowing medium. Located within this caliber tube b two electrodes a1 and a2, which are advantageously designed as grid electrodes are. These electrodes and a2 are connected to a constant voltage via an ammeter created. The measuring instrument, the voltage source and any upstream apparatus to keep the measuring voltage constant are not shown. Between the electrodes there is an Ionisa.tor, which is also not shown in the drawing is.

Als Ionisator kann zweckmäßig eine radioaktive Zelle verwendet werden, die über eine lange Zeit hinweg genügend konstante Ionisationseigenschaften hat.A radioactive cell can be used as an ionizer, which has sufficiently constant ionization properties over a long period of time.

Bei der in Abb. 2 dargestellten Ausführungsform der Meßvorrichtung sind die Elektroden a1, a2 in gesonderten Räumen dl, e1 und d2, d2 angeordnet.In the embodiment of the measuring device shown in Fig. 2 the electrodes a1, a2 are arranged in separate spaces dl, e1 and d2, d2.

Der Vorteil eines solchen Strömungsmessers bzw. Mengenmeßger.ätes für bewegte Gase und Dämpfe beruht einmal. auf der überaus einfachen konstruktiven Anordnung. Ein weiterer Vorteil dieser Anordnung besteht in der Präzision der Meßangaben in ihrer genauen Proportionalität von Null bis zum Maximum ohne irgendwelche Fehlermöglichkeiten und schließlich in dem Fortfall aller Vorrichtungen, die sonst bei Dampfmessern zur Kompensation des Druckes und der Temperatur erforderlich sind; denn die Berücksichtigung des Druckes und der Temperatur findet bereits in der Ionisation des bewegten gasförmigen Mediums nach bekannten Gesetzen proportional der Dichte ihren Ausdruck.The advantage of such a flow meter or quantity measuring device for moving gases and vapors is based once. on the extremely simple constructive Arrangement. Another advantage of this arrangement is the precision of the measurements in their exact proportionality from zero to the maximum without any possibility of error and finally in the elimination of all devices that would otherwise be found in steam knives are required to compensate for pressure and temperature; because the consideration the pressure and the temperature already takes place in the ionization of the moving gaseous Medium according to known laws proportional to the density their expression.
