<p>A flowmeter comprising means (12) for conducting fluid the rate of flow of which is to be measured, flexure means (15) arranged to undulate in response to fluid flow, whereby a travelling wave is propagated along the flexure means, and means (23, 24) for detecting a parameter of the travelling wave which is a function of the rate of flow of the fluid. The parameter of the travelling wave may be the frequency or the velocity of propagation thereof, for example.</p> |
