Description
Durchflußmengenmesser für Flüssigkeiten und Gase. Durchflußniengenmesser, bei denen aus der Hubhöhe eines Schwebekörpers von Scheiben-oder Kegefform oder aus dem Vorschub eines Kolbens in einem mit Löchern oder Schlitzen versehenen Zylinder die Durchflußmenge in der Zeiteinheit bestimmt wird, sind bekannt. Alle diese Vorrichtungen sind jedoch zu genaueren Messungen nicht geeignet, teils weil die Hubhöhe oder der Vorschub der Durchflußmenge nicht proportional ist, teils weil die Reibung zu groß ist oder Wirbelströrne nicht vermieden sind oder aus anderen Gründen.Flow meter for liquids and gases. Flow meter, where from the lifting height of a float of disk or cone shape or from the advance of a piston in a cylinder provided with holes or slots the flow rate is determined in the unit of time are known. All of these devices are not suitable for more precise measurements, partly because the lifting height or the Feed rate is not proportional to the flow rate, partly because the friction is too great or eddy currents are not avoided or for other reasons.
Alle diese Fehler sind bei der vorliegenden Erfindung vermieden. a ist das lotrecht gerichtete Ende einer Rohrleitung. b ist ein oben geschlossenes, über a gestülptes, das feste Rohr nicht berührendes, mit Längsschlitzen c, c, z. B. vier symmetrisch gelegenen Schlitzen versehenes ]Bohr, das irgendwie, z.B. durch vier an dem festen Rohr angebrachte, in die Schlitze hineinragende Bleche geführt und fast ohne Reibung auf. und ab beweglich ist. Überträgt man die Bewegung des Schweberohres z. B. durch Zahnstange und Zahnrad auf einen Zeiger, der vor einer Kreisskala spielt, so kann man die Durchflußstärke jederzeit ablesen.All of these errors are avoided in the present invention. a is the perpendicular end of a pipe. b is a closed top, slipped over a, not touching the solid tube, with longitudinal slots c, c, z. B. four symmetrically located slots provided] Bohr, which somehow, for example, through four attached to the fixed tube, protruding sheets into the slots and almost without friction. and from is movable. If you transfer the movement of the floating tube z. B. by rack and gear on a pointer that plays in front of a circular scale, so you can read the flow rate at any time.
Die Vorrichtung läßt sich auch in eine geschlossene Rohrleitung einbauen und ferner auch mit einer der bekannten Registrier- oder Zählvorrichtungen in Verbindung bringen, um die gesamte während einer Zeit durchfließende Menge zu registrieren oder zu zählen. Wird der Absperrhahn der Rohrleitung geöffnet, so fließt die Flüssigkeit oder das Gas in wirbelfreiem Strahl in dem festen Rohr aufwärts und hebt das Schweberohr so weit in die Höhe, bis die Druckdifferenz innerhalb und außerhalb des Shweberohres gleich dem auf die Flächeneinheit des Querschnittes entfallenden Gewicht des Rohres geworden ist. Da aber dieses Gewicht unveränderlich ist, so ist auch die Druckdifferenz und in weiterer Folge auch die lin-eare Durchtrittsgeschwindigkeit durch die Schlitze unveränderlich. Daraus folgt aber, daß, da die Schlitze von oben bis unten genau gleiche Breite haben, die in der Zeiteinheit durch den freien Teil der Schlitze tretende Menge genau der Hubhöhe des Schweberohres proportional ist.The device can also be installed in a closed pipeline and also in connection with one of the known registration or counting devices in order to register the total amount flowing through during a time or to count. If the stopcock of the pipeline is opened, the liquid flows or the gas in a vortex-free jet goes up the fixed tube and lifts the floating tube so far upwards, until the pressure difference inside and outside of the shuttle pipe equal to the weight of the pipe that corresponds to the unit area of the cross-section has become. But since this weight cannot be changed, so is the pressure difference and subsequently also the linear speed of passage through the slots immutable. It follows from this, however, that the slots are exactly from top to bottom have the same width as that in the unit of time through the free part of the slots stepping amount is exactly proportional to the lifting height of the floating tube.
Die Vorrichtung läßt sich als Gas-, Dampf-und Wassermesser sowie auch für andere Flüssigkeiten verwenden.The device can be used as a gas, steam and water knife as well use for other liquids.
