Abstract
Official abstract text for this publication.
An apparatus for determining the homogeneity of a fluid flow in a pipe, such as a reducing-agent flow in an exhaust-gas pipe of an internal combustion engine, including a transmitter arranged on a light-transmissive region of the pipe and a diametrically opposite detector. The transmitter and detector being coupled such that they are rotatable through an angle of 360° about a rotational axis which is located substantially in the axis of symmetry of the pipe. The transmitter and the detector are rotated through at least 360° about the rotational axis, thus capturing an intensity of the detected light over the rotation angle, and from this a homogeneity of the fluid flow is deduced.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus configured for determining the homogeneity of a fluid flow passing through the apparatus, the apparatus comprising: a pipe configured to transport or contain a fluid; a light-transmissive region of the pipe extending around a circumference of the pipe; at least one optical transmitter configured to transmit an optical signal through the light-transmissive region of the pipe; and at least one optical detector positioned diametrically…
