ABSTRACT:
A flowmeter comprises a chamber having a rotational symmetry about an axis, provided with a tangential fluid inlet and an axial outlet. The outlet and inlet means cooperate for generating a vortex upon circulation of fluid through the chamber; a speed detector comprises at least one transmitting thermo-element and one receiving thermo-element angularly spaced about the said axis and located in a zone where the circumferential speed of the vortex is proportional to the flow rate.
