Wassermenge.Amount of water.

Den Gegenstand vorliegender Erfindung bildet ein selbstregistrirender Apparat zum Messen der in Rohrleitungen flieisenden Wassermengen, bei dem diese Mengen aus der Durchnuisgeschwindigkeit und der Zeit bestimmt werden. Die Geschwindigkeit wird in bekannter Weise durch den Druckunterschied vor und hinter einem in die Leitung eingeschalteten Widerstandrohr gemessen. Dieser selbst wird beispielsweise durch die Ausbiegungen einer Membran gemessen, deren beide Seiten unter dem Druck vor und hinter dem Widerstandsrohr stehen.The subject of the present invention is a self-registering apparatus for Measuring the amount of water flowing in the pipelines at which these amounts are derived from the Can be determined by speed and time. The speed is in known way by the pressure difference upstream and downstream of a switched on in the line Resistance tube measured. This itself is, for example, caused by the bends a membrane measured, both sides of which under the pressure in front of and behind the Stand resistance tube.

Die Erfindung besteht in einer Einrichtung, durch welche die Ausweichungen der Membran in der Weise auf die Antriebsvorrichtung für das Zählrad übertragen werden, dafs das Zählrad immer mit einer der Durchfluisgeschwindigkeit des Wassers proportionalen Geschwindigkeit umläuft. Als Uebertragungsorgan dient eine Schnecke, welche der Ausweichung der Membran entsprechend gedreht wird und in deren Gewinde .das die Antriebsvorrichtung für das Zählwerk regelnde Organ eingreift. Die Gewindesteigung der Schnecke kann so berechnet werden, dafs sich die Antriebsvorrichtung immer in der Weise einstellt, dafs dem Zählrad eine der Durchflufsgeschwindigkeit des. Wassers proportionale Umdrehungsgeschwindigkeit ertheilt wird.The invention consists in a device by which the deflections of the membrane are transmitted in such a way to the drive device for the counting wheel that the counting wheel always with a speed proportional to the flow speed of the water running around. A screw serves as the transmission element, which is rotated according to the deflection of the membrane and in the thread .das engages the drive device for the counter regulating organ. The thread pitch of the worm can be calculated so that the drive device always adjusts in such a way that the counter wheel one of the flow rate of the water proportional speed of rotation is imparted.

In dem Gehäuse 1 (Fig. 1 und 2) ist eine Membran 2 vorgesehen. Das Gehäuse 1 ist zu einem Rohr ausgebildet, welches in die Rohrleitung 3 in der aus Fig. 2 ersichtlichen W^reise eingeschaltet werden kann. Man nehme an, das Wasser trete, aus den Wasserwerken kommend, in Pfeilrichtung (Fig. 2) bei der Stelle 5 in die Leitung 3 ein, welche in bekannter Weise durch die Widerstände 4 eine Querschnittsverengung aufweist. Diese Querschnittsverengung hat den Zweck, dafs das Wasser durch die Leitung 3 nicht in voller Geschwindigkeit fliefsen kann, sondern auf die Membran 2, sofern es in der Pfeilrichtung fliefst, derart in ebenfalls bekannter Weise einwirkt, dafs diese Membran nach rechts je nach dem auftretenden Druck mehr oder weniger ausgebogen wird. Die Membran 2 ist mit einer Stange 6 (Fig. 1) verbunden, welcher eine der Gröise der Ausbiegung entsprechende Längsbewegung ertheilt wird. - An dem einen freien Ende dieser Stange ist dieselbe mit einer Verzahnung versehen, und diese Verzahnung greift in einen Trieb der Welle 7 ein. Die Welle 7 wird daher je nach der Gröise des Ausschlages der Membran 2 um einen geringeren oder gröfseren Winkel um ihre Achse gedreht. Die Bewe-A membrane 2 is provided in the housing 1 (FIGS. 1 and 2). The housing 1 is formed into a tube which ^r in the pipeline 3 in the manner shown in Fig. 2 W can be switched on ice. Assume that the water, coming from the waterworks, enters the line 3 in the direction of the arrow (FIG. 2) at point 5, which has a cross-sectional constriction due to the resistors 4 in a known manner. This cross-sectional narrowing has the purpose that the water cannot flow through the line 3 at full speed, but on the membrane 2, if it flows in the direction of the arrow, acts in such a known manner that this membrane moves to the right depending on the pressure occurring is bent more or less. The membrane 2 is connected to a rod 6 (FIG. 1) which is given a longitudinal movement corresponding to the size of the deflection. - At one free end of this rod the same is provided with a toothing, and this toothing engages in a drive of the shaft 7. The shaft 7 is therefore rotated around its axis by a smaller or larger angle, depending on the magnitude of the deflection of the membrane 2. The moving

Claims

The movement of the membrane 7 is transferred with the aid of a wheel 8 (FIGS. 1 and 6) to a rod 9 which is guided by rollers 10 and a pen 11 carries. The pen 11 is in contact with a sheet of paper applied to a cylinder 12 and this cylinder 12 is constantly set in rotation by a clockwork provided in the housing 13. For this reason, it is possible to determine on a sheet of paper carried by the cylinder 12 the pressure magnitudes of the water flowing through the line 3 occurring at the most varied of times. In order to be able to infer the respective quantities of water consumed directly from the pressure fluctuations, the size of the thread pitch of the screw to be used is determined from the diagram shown in FIG. 3. On the positive side of the abscissa, the number of revolutions of the Mefsrades respectively. the consumed amounts of water determined by tests are removed, while the deflections of the membrane BEZW on the ordinate. the revolutions of the shaft 7 are plotted. This then results in a curve according to which the screw 14 shown in FIG. 4 is cut. If one uses a worm designed in this way and lets it act in the manner shown in FIG pushed back and forth. This back and forth movement is transmitted to a carriage 17 which runs on rails 19 with rollers 18. The cylinder 20 driven by a clockwork transmits its rotation to a roller 21, from which a disk 22 is set in uniform rotation. This disk 22 sits on the carriage 17 and is therefore pushed back and forth with it. In the position shown in Fig. 5, the Mefsrad 23, since it is just in contact with the center of the disk 22, will not rotate at all. Depending on the displacement of the rod 16 and the disk 22, however, the meter wheel 23, which is connected to a registering counter and drives it precisely according to the amount of water consumed, are driven at a different speed. The device not only shows the flow of water in one direction, but also, since the water flowing back causes the membrane 2 to bend in the opposite direction, it will also show exactly at what point in time water flowed back to the starting point. The threaded spindle is a means which enables the respective pressure fluctuations and the amount of water consumed to be recorded in an extremely sensitive and reliable manner.
