Abstract
A method of fluid flow measurement includes a emitting a light beam into a pipe through which a fluid flows, the light beam illuminating the fluid flowing in the pipe, using a light detector array to detect light caused by scattering of the beam with particles found in the fluid, the light beam being outside a field of view of the light detector array, dividing the field of view of the light detector array into layers, and determining an instantaneous flow velocity in each of the layers as a function of signals transmitted from the light detector array in each of the layers.
Claims8
A fluid flow measurement method comprising:
- emitting a light beam having a form of a light sheet into a pipe through which a fluid flows, said light beam illuminating the fluid flowing in said pipe;
- using a light detector array to detect light caused by scattering of said beam with particles found in said fluid, said light beam being outside a field of view of said light detector array;
- dividing the field of view of said light detector array into layers that intersect the light sheet at cross sections of equal volume cylindrical shells of the flowing fluid;
- and
- determining an instantaneous flow velocity for each of said equal volume cylindrical shells as a function of signals transmitted from said light detector array for each of said associated cross sections.
