Abstract
A flow volumeter for liquids has an impeller chamber and an inflow chamber partially encircling the impeller chamber. In order to achieve a symmetrical load on the bearing for the impeller axis, the flow-directing openings in the circumferential wall of the impeller chamber, said openings facing the inflow openings of the inflow chamber, have smaller dimensions that the flow-directing openings facing away from the inflow chamber. In addition, the upper and lower regions of the impeller chamber are provided with outlet openings. Finally, the flow cross section of the inflow chamber decreases in size in the direction of flow.
