Abstract: A flowmeter for liquids has a measuring housing, which encloses and rotatably mounts an impeller, said measuring housing comprising a one-piece supply pipe and discharge pipe, wherein the impeller is eccentrically arranged in the discharge pipe after a nozzle-forming constriction. A sensor encoder is associated with the impeller and a sensor which responds to the sensor encoder is provided on the measuring housing for determining the amount of liquid flowing through the measuring housing on the basis of the revolutions of the impeller. The outer diameter corresponding to the impeller is smaller than the nominal inner diameter of the discharge pipe, enabling it to be pushed into the one-piece pipe.
