Abrégé
(EN)



The flow measurement device of the present invention incorporatesnumerous
novel features. The device includes a displacement measuring device (160) to
measure the position of a movable plate member (132), a self-oscillation
dampener (140) to dampen oscillations of the plate member (132), one or more
stiffening members engaging or incorporated into the plate member (132) to
increase the resonant frequency of the plate member (132) and reduce flutter,
and a conduit (124) providing for differing directions (148, 164) of air flow
at different points along its length to eliminate the effects of gravity on
flow measurements.
