Description

Die Erfindung bezweckt die Messung von Dampf-, Gas- oder Flüssigkeitsmengen durch Betätigung eines Zählwerkes.The invention aims to measure the amount of vapor, gas or liquid Operation of a counter.

Der in bekannter Weise durch Drosselung erhaltene Druckabfall wird durch die Kammer a, der innere Leitungsdruck durch die Kammer b auf eine mit Quecksilber gefüllte und mit dem Gehäuse c leitend verbundene U-förmig gebogene Röhre d übertragen. DieThe pressure drop obtained in a known manner by throttling is transmitted through chamber a, the internal line pressure through chamber b to a mercury-filled tube d which is conductively connected to housing c. the

ίο Kammern α und b sind beim Dampfmessen bis zu einer den in ihnen herrschenden Drücken entsprechenden Höhe mit Kondenswasser, im übrigen — wie bei einem Windkessel — mit gepreßter Luft gefüllt. Die in dem Schenkel e befindliche Quecksilbersäule trägt einen mit ihr leitend verbundenen und in einen Kontakt f endenden Schwimmer g. Das Neue besteht nun darin, dai3 sich der Schwimmer dem Druckunterschied h entsprechend vor der mit Kontakten versehenen Trommel i und parallel zu ihr auf und ab bewegt. Die Trommel i wird durch die Friktionsscheibe k angetrieben. Auf dieser ist, durch Kolben I radial verschiebbar, das durch Uhrwerk s angetriebene Reibungsrädchen η angeordnet. Der Kolben I bewegt sich dicht schließend in dem nach außen mit der Atmosphäre verbundenen Zylinder p und erhält vom Innern' der Kammer α den in dieser befindlichen Druck, als Gegendruck den Druck der Atmosphäre und der Feder q. Kolben I und Fej der q sind so bemessen, daß die durch sie j beeinflußte Lage des Rädchens η auf der Friktionsscheibe k der Trommel i den Leitungsdrücken proportionale Geschwindigkeiten 3; erteilt. Auf der Trommel befinden sich Nasen r derart angeordnet, daß deren Anzahl dem Quadrat wurzel wert aus h, multipliziert mit einer dem Apparat eigentümlichen Konstanten, entspricht. Durch die Drehung der 4< Trommel werden die Nasen mit dem Kontakt f in Berührung gebracht, wodurch in bekannter Weise Stromschlüsse hervorgebracht und gezählt werden können.ίο When measuring steam, chambers α and b are filled with condensed water up to a level corresponding to the pressures prevailing in them, and otherwise - as in an air chamber - filled with compressed air. The mercury column located in the leg e carries a float g that is conductively connected to it and ends in a contact f. The novelty consists in the fact that the float moves up and down in front of the drum i provided with contacts and parallel to it, according to the pressure difference h. The drum i is driven by the friction disk k . The friction wheel η driven by the clockwork s is arranged on this, radially displaceable by piston I. The piston I moves tightly in the cylinder p , which is connected to the outside with the atmosphere, and receives the pressure from inside the chamber α , the pressure of the atmosphere and the spring q as counterpressure. Pistons I and Fej of q are dimensioned in such a way that the position of the small wheel η on the friction disc k of the drum i, influenced by them j, speeds proportional to the line pressures 3; granted. On the drum there are lugs r arranged in such a way that their number corresponds to the square root value of h multiplied by a constant peculiar to the apparatus. The rotation of the 4 <drum brings the lugs into contact with the contact f , whereby current circuits can be produced and counted in a known manner.

Claims (1)

Patent-Anspruch:Patent claim: Dampf-, Gas- oder Flüssigkeitsmesser, bei dem der durch eine Drosselung der Leitung hervorgerufene Druckunterschied durch ein Flüssigkeitsmanometer gemessen wird, auf dessen Spiegel sich ein Schwimmer mit Kontakt bewegt, dadurch gekennzeichnet, daß sich die Drehgeschwindigkeit einer mit Kontakten versehenen Trommel gemäß den verschiedenen Leitungsdrucken selbsttätig einstellt, so daß bei entsprechender Anordnung der Kontakte die Summierung der Quadratwurzelwerte aus den Druckunterschieden und in Abhängigkeit von dem Leitungsdruck selbsttätig erfolgt.Vapor, gas or liquid meter, in which the by a throttling of the Line-induced pressure difference measured by a liquid manometer is, on the mirror of which a float moves with contact, characterized in, that the speed of rotation of a drum provided with contacts varies according to the various line pressures automatically adjusts, so that with the appropriate arrangement of the contacts the summation of the square root values takes place automatically from the pressure differences and as a function of the line pressure.
