Abstract
The device (20) for measuring the flowrate of a liquid in a pipeline, comprises, on a mount (21) fixed to a perimeter of the pipeline, a part (24) rotatably moveable around a first shaft (25) through the action of the flow of liquid. The device also comprises: a mass (33) supported by an arm (29) in rotation around a second shaft (32); an angle multiplier (26, 27) configured to transform the angular movement of the moveable part into an angular movement of the arm supporting the mass, this arm travelling through an angle greater than the angle travelled by the moveable part; and a sensor (37) of the position of the arm supporting the mass.
