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.
IPC Classes ?
- G01F 1/661 - Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow by measuring frequency, phase shift or propagation time of electromagnetic or other waves, e.g. using ultrasonic flowmeters using light
- G01N 11/04 - Investigating flow properties of materials, e.g. viscosity or plasticityAnalysing materials by determining flow properties by measuring flow of the material through a restricted passage, e.g. tube, aperture
- G01F 1/66 - Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow by measuring frequency, phase shift or propagation time of electromagnetic or other waves, e.g. using ultrasonic flowmeters

Abstract
A method of fluid flow velocity measurement includes emitting a beam from a light source via a first window into a pipe through which a fluid flows, the beam illuminating the fluid flowing in the pipe, using a light detector array, which is coupled via a second window to the pipe and which is outside a field of view of the light detector, to detect light caused by scattering of the beam with particles found in the fluid, and determining a velocity of the fluid flowing in the pipe as a function of signals from the light detector array.
