ABSTRACT:
An apparatus for measuring a flow rate of a fluid by a cantilever type pressure receiving plate which is disposed within a flow channel such that a substantially perpendicular fluid flow abuts against the surface at one end portion of the plate so that the cross-sectional area of said fluid flow opposing the end portion of the plate is increased when the end portion of the plate is deflected by the acting forces of the fluid flow.
