Description
Strömungsmesser Die bekannten Strömungsmengemnesser mit einer aus einer Sperrflüssigkeit auftauchenden Glocke, in deren Wand Durchtrittsöffnungen für das zu messende Gas vorhanden sind, sind nicht immer für die in der Praxis vorkommenden Betriebsverhältnisse geeignet. So müssen z. B. bei Verwendung als Kontrollinstrument zum Nachprüfen im Betrieb befindlicher Meßinstrumente und als Schadensucher zur Ermittlung von @Undichtigkeiten vom Strömungsmesser nicht nur die maximal auftretenden großen, sondern auch außerordentlich geringe Durchflüsse richtig angezeigt werden.Flow meter The well-known flow meter with one out a sealing liquid emerging bell, in the wall of which there are passage openings for the gas to be measured are not always available for those that occur in practice Suitable for operating conditions. So z. B. when used as a control instrument for checking measuring instruments in operation and as a damage searcher for Determination of @leakages from the flow meter not only the maximum occurring large, but also extremely low flow rates are displayed correctly.
Um diesen Nachteil zu beseitigen, werden derartige Strömungsmesser dadurch verbessert, daß erfindungsgemäß. außer der üblichen, den Durchflußwert angebenden Skala eine Skala angebracht ist, auf der das Volumen desjenigen jeweils aufgetauchten Glockenteiles abgelesen werden kann, der keine Durchtrittsöffnungen hat. Die Glocke wir.kt also in diesem Teil ihres Hubes als Gasometer.In order to overcome this disadvantage, such flow meters improved by the fact that according to the invention. except for the usual ones that indicate the flow rate A scale is attached on which the volume of each emerged Bell part can be read, which has no openings. The bell so we act as a gasometer in this part of its stroke.
Abb. i zeigt einen der bekannten Strömungsmesser mit Tauchglocke, deren Wandung durchbrochen ist. Im Gehäuse a befindet sich die in eine Sperrflüssigkeit b tauchende Glocke e, deren Mantel bei r nm durchbrochen ist. Das zu messende Medium strömt durch das Rohr k unter die Glocke c, hebt diese entsprechend der jeweiligen Augenblicksleistung, tritt durch die Durchbrechungen m m in das Gehäuse a und strömt durch das Rohr i wieder aus. Die Nullstellung c' der Glocke und der höchste Stand c" der Glocke sind punktiert gezeigt.Fig. I shows one of the known flow meters with a diving bell, the wall of which is perforated. In the housing a there is the bell e which is immersed in a sealing liquid b and whose jacket is broken through at r nm. The medium to be measured flows through the tube k under the bell c, lifts it according to the respective momentary power, passes through the openings mm into the housing a and flows out again through the tube i. The zero position c 'of the bell and the highest level c "of the bell are shown in dotted lines.
Beim Gegenstand vorliegender Erfindung wird der Mantel der Glocke c für die Strömungsmessung nur in einem bestimmten Höhenabschnittr mit.einer Durchbrechung g versehen, .während der geschlossene obere Abschnitts der Glocke zur Volumenmessung dient (s. Abb. 2).When the subject of the present invention is the shell of the bell c for the flow measurement only in a certain height section with an opening g, .during the closed upper section of the bell for volume measurement serves (see Fig. 2).
Dementsprechend .erhält auch die Anzeigeskala zwei verschiedene Teilungen. Die untere Teilung s' entspricht dem Glockeninhalts, die obere Teilungr' zeigt die jeweilige Augenblicksleistung. Bei kleinen Durchflüssen kann man durch eine Umleitung mit Absperrorgan t (s. Abb. i) die Glocke in die Nulllage bringen. Nach Absperren der Umleitung t erfolgt 'Volumenmessung, bis durch das Heben der Glocke die Durchbrechung et den Spiegel der Sperrflüssigkeit erreicht. Von diesem Augenblick an erfolgt die Strömungsmessung. Unter Zuhilfenahme einer Uhr kann aus der Volumenmessung die jeweilige Augenblicksleistung in einfachster Weise errechnet werden.Accordingly, the display scale also has two different divisions. The lower division s 'corresponds to the bell content, the upper division r' shows the respective instantaneous performance. In the case of small flows, a diversion can be used Use the shut-off device t (see Fig. i) to bring the bell into the zero position. After locking the diversion takes place t 'volume measurement until the opening is made by lifting the bell et reaches the level of the sealing liquid. From that moment on, that happens Flow measurement. With the help of a clock, the respective Instantaneous power can be calculated in the simplest way.
Das beschriebene Ausführungsbeispiel zeigt eine neinfache, an sich bekannte Anzeigevorrichtung, die aus der am oberen Teil der Glocke angebrachten. Stange d nebst Zeigere besteht. Der Zeiger e bewegt sich in einem Glasrohr f und ist daher von außen sichtbar. Die Ablesungen der jeweiligen Augenblicksleistungen erfolgen an den Skalengg.The embodiment described shows a multiple, per se known display device, which from the attached to the upper part of the bell. Rod d and hands exist. The pointer e moves in a glass tube f and is therefore visible from the outside. The readings of the respective instantaneous performance take place at the Skalengg.
Es besteht ohne weiteres die Möglichkeit, die Bewegung der Glocke nach außen auf eine Schreibvorrichtung zu übertragen, unter Verwendung einer Stopfbuchse oder anderer bereits bekanntgewordener Einrichtungen. Das zu beschreibende Formular kann in zwei Abschnitte geteilt werden: Der. untere Abschnitt für Volumenmessung und der obere für die Strömungsmessung. Aus dem beschriebenen Formularteil für Volumenmessung kann das gemessene Volumen und die dazugehörige Zeit abgelesen werden. Der Neigungswinkel der aufgezeichneten Kurven ist ein Maß für die jeweilige Augenblicksleistung.There is easily the possibility of moving the bell to the outside on a writing device using a gland or other institutions that have already become known. The form to be described can be divided into two sections: The. lower section for volume measurement and the upper one for flow measurement. From the described part of the form for volume measurement the measured volume and the associated time can be read off. The angle of inclination of the recorded curves is a measure of the respective momentary performance.
Die in Abb. i gezeigten Rohre l und h mit eingebauten Absperrorganen dienen zur Entlüftung des Gehäuses a und der Glocke c, wenn der Strömungsmesser zum Messen von Flüssigkeiten Verwendung findet.The pipes l and h shown in Fig. I with built-in shut-off devices serve to vent the housing a and the bell c when the flow meter for measuring liquids is used.
