ABSTRACT:
A device for measuring the mass flow of a fluid consists of a body which is arranged to resonate under the influence of a travelling flexure wave. Various embodiments of the invention are described. In certain embodiments in which the resonating body is in the form of a cylinder, the frequency of resonance is related to the mass of fluid flowing over the surface of the cylinder. In other embodiments, the wave velocity of the flexure wave is modified by a fluid flowing over the surface of the cylinder and amplitude modulation is introduced into the resonating flexure wave. The amplitude modulation is related to the mass of fluid flowing and an output indicative of the mass flow is produced. In further embodiments the body is in the form of a flat vane. The wave velocity of the flexure wave is modified by the fluid over the surface of the vane, and the wave velocity is monitored by comparing the relative phases of the flexure wave at different points along the vane. The phase difference is related to the mass of fluid flowing and an output indicative of the mass flow is produced.
