(57)< Abstract > The flow measurement equipment of this invention has had many new features. As for the device, the movable plate component (132) the displacement measurement equipment in order to measure position (160) with, the plate component (132) the vibration in the point where the self-oscillation attenuation device in order to be attenuated (140) with, the plate component (132) it makes resonance frequency increase, the plate component in order at the same time to decrease flutter (132) it engages, or one which is installed or paralleled to the length in order to remove the plural reinforcement components and the action of the gravity for flow measurement and differs, the direction which differs to the air style (148,164) the pipe which is offered (124) withIt includes.本発明のフロー測定装置は、多くの新規な特徴を有している。装置は、可動なプレート部材(132)の位置を測定するための変位測定装置(160)と、プレート部材(132)の振動を減衰するための自己振動減衰装置(140)と、プレート部材(132)の共振周波数を増大させ、かつフラッターを低減するためのプレート部材(132)に係合するかまたは組み込まれる1つまたは複数の補強部材と、フロー測定に対する重力の作用を排除するためにその長さに沿った異なる点で、空気流に異なる方向(148,164)を提供する導管(124)とを含む。
