| 摘要 |
<p>The present invention relates to a flow velocity measuring apparatus which provides a distinct, measurable pattern of vortices known as Karman Vortex Generation. The apparatus is arranged to include a plurality of vortex producing obstructions which co-operate to provide a high signal output. The flowmeter is designed to use a vibration sensor which is accessible from the exterior of the pipe carrying the fluid being measured.</p> |
