Description

Dampf- oder Flüssigkeitsmesser mit Staurand. Zur Messung der eine Rohrleitung durchströinenden Dampfmenge oder anderen Flüssigkeitsmengen werden nach dem sogenannten Strömungsmesserverfahren Stauscheiben eingesetzt, welche den Querschnitt nach bestimmtem Verhältnis verengen. Die vor und hinter den Stauscheiben entstehende Druckdifferenz dient dann zum Messen der Geschwindigkeit oder Menge.Vapor or liquid meter with a rim. To measure the one The amount of steam flowing through the pipeline or other amounts of liquid are after the so-called flow meter method baffle plates are used, which the cross-section narrow according to a certain ratio. The ones in front of and behind the baffle plates The pressure difference is then used to measure the speed or quantity.

Ein Übelstand dieses Verfahrens ist es, daß für das Einsetzen der Meßscheiben eine Flanschverbindung vorhanden sein muß. Wenn dieselbe fehlt oder unmittelbar neben einem Ventil o. dgl. sitzt, ist die Messung nicht möglich, oder es muß eine neue Flanschverbirxlung geschaffen werden.A drawback of this procedure is that for the onset of the A flange connection must be available for measuring disks. If the same is missing or sits directly next to a valve or the like, the measurement is not possible, or a new flange connection must be created.

Die auf der Zeichnung dargestellte Einrichtung vermeidet diese Schwierigkeiten. Die erforderliche Stauscheibe S sitzt nicht in der Flanschenverbindung F, sondern ist an einer dünnwandigen Blechhülse H befestigt, weiche eine gewisse Strecke, je nach Rohrdurchmesser, z. B. 200 mm, in das Rohrlichte hineinragt. Die geringe Verengung hinter der Stauscheibe (in der Dampfrichtung gedacht) hat gar keinen Einfluß auf die Messung, da sie bei ,der Eichung des Instrumentes berücksichtigt wird.The device shown in the drawing avoids these difficulties. The required baffle plate S is not located in the flange connection F, but is attached to a thin-walled sheet metal sleeve H, soft a certain distance, depending according to pipe diameter, e.g. B. 200 mm, protrudes into the tube light. The small constriction behind the baffle (thought in the direction of the steam) has no influence at all the measurement, as it is taken into account when calibrating the instrument.

Von den zur Druckentnahme dienenden Rohrstutzen R, und R. muß Az in das Innere der Hülse H geführt werden, während R, nur in das Lichte des Rohres führt.Az in the inside of the sleeve H, while R, only leads into the light of the tube.

Die gezeicbnete Einrichtung kann bei der :Messung aller strömenden Medien, Gase, Wasser, Dampf u. a. verwendet werden.The device shown can be used to: Measure all flowing Media, gases, water, steam, etc. be used.
