Method and device for the determination of the local concentration of microbubbles of a liquid or droplets of a fluid, and the size of those - ci.

摘要

The subject of the invention is a method and device for determining the concentration and the size of microbubbles in a liquid or of droplets in a fluid, within a measurement volume V. An optical emitter system E generates parallel rays I directed onto V, whilst an optical detector system P receives the rays RT which have undergone total reflection at the surface of a microbubble 2 in V. A sensor 9 determines the intensity of the light transmitted by P. IMAGE
