Flügelradwassermesser.
Die Erfindung bezieht sich auf einen Flügelradwassermesser mit einer besonderen Messkammer und einer die Flüssigkeit einer der Eintrittsöffmmgen in die Messkammer zuführenden, in der Achse dieser Öffnung angeordneten Düse mit beweglicher Abdeckklappe. Die Erfindung besteht darin, dass die Düsenmündung in diese Eintrittsöffnung hineinragt. Der Wasserstrahl wird dadurch auch bei kleinen Durchflussmengen dem Flügelrad ohne Richtungsänderungen zugeführt. Er beaufschlagt das Flügelrad unmittelbar, wodurch ein sehr genaues Messergebnis auch bei sehr geringen Durchflussmengen erzielt wird.
Die an der Düse angelenkte Klappe darf keine seitlichen Wangen aufweisen, so dass, wenn von einer gewissen Durchflussmenge angefángen die Klappe sich hebt, das Wasser auch durch die andern Öffnungen in die Messkammer eintritt. Die Klappe liegt in der Ruhestellung annähernd waagrecht, so dass, wenn sie sich zu heben beginnt, ihr dem Flüssigkeitsstrahl entgegenwirkendes Gewicht ein zu rasches Anheben verzögert und die Wirkung der Düse auf das Flügelrad verlängert wird.
Die Fig. 1 und 2 der Zeichnung zeigen schematisch und beispielsweise eine Ausführungsform der Vorrichtung : ist die Düse, B die Klappe und 0 die Eintrittsöffnung in die Messkammer D, in welche die Düsenmündung hineinragt.

Impeller water meter.
The invention relates to an impeller water meter with a special measuring chamber and a nozzle with a movable cover flap which supplies the liquid to one of the inlet openings into the measuring chamber and is arranged in the axis of this opening. The invention consists in that the nozzle mouth protrudes into this inlet opening. The water jet is thus fed to the impeller without changing direction, even with small flow rates. It acts on the impeller directly, whereby a very accurate measurement result is achieved even with very low flow rates.
The flap hinged to the nozzle must not have any side cheeks, so that when the flap rises from a certain flow rate, the water also enters the measuring chamber through the other openings. In the rest position, the flap lies approximately horizontally, so that when it begins to rise, its weight counteracting the liquid jet retards too rapid a rise and the effect of the nozzle on the impeller is lengthened.
1 and 2 of the drawing show schematically and for example an embodiment of the device: is the nozzle, B is the flap and 0 is the inlet opening into the measuring chamber D, into which the nozzle mouth protrudes.
