Abstract: The gyrometer comprises a cavity filled with a fluid in the form of a body of revolution having an axis coinciding with the axis of a rotation to be measured. An excitation transducer and a measuring transducer are disposed on the wall of the cavity in a same cross section and offset at an angle of 90.degree.. The excitation transducer excites a first acoustic resonance mode of the cavity and the measuring transducer measures a second mode of resonance induced by Coriolis forces when the cavity is subjected to the rotation to be measured. Such a gyrometer, less sensitive to mechanical embodiment inaccuracies, is assembled on, a moving body, for example, in order to measure its speed(s) of rotation.
