Two dimensinal flow analyzer |
摘要 |
Apparatus for analyzing flowing fluid which contains light scattering particles comprises a light source; beam-expansion means to expand a light beam from the source to provide a two-dimensional sheet of light, there being at least a component of the fluid flow in the plane of said sheet; sensing means to sense light scattered by the particles; switch means arranged so that the sensing means senses scattered light only intermittently; and control and calculating means to calculate from the intermittently sensed light a property of the flow.
