Abstract
Apparatus for use in monitoring particles in a fluid flow comprises: a duct (1) for receiving the fluid flow; light generating means (6) adjacent the duct for transmitting light into the fluid flow via a first at least partially light-transmissive part (4) of the duct; light-responsive detection means (7) adjacent a second at least partially light-transmissive part (5) of the duct for receiving light from the light generating means which has passed through the fluid flow; processing means (8) for location remotely from said duct; and means (9) for coupling the processing means with the detection means, the processing means being adapted for processing signals therefrom to provide data relating to particles in the fluid flow.
Claims24
Apparatus for use in monitoring particles in a liquid flow, comprising:
- a duct in the form of a pipe section for receiving the liquid flow;
- light generating means adjacent the pipe section for transmitting light into the liquid flow via a first at least partially light-transmissive part of the pipe section;
- light-responsive detection means adjacent a second at least partially light-transmissive part of the pipe section for receiving light from the light generating means which light has passed through the liquid flow;
- processing means for location remotely from said pipe section;
- means for coupling the processing means with the detection means, the processing means being adapted for processing signals therefrom to provide data relating to particles in the liquid flow;
- wherein inside said pipe section, each of said first and second at least partially light-transmissive parts has a non-stick coating;
- the surface of said first at least partially light-transmissive part inside said pipe section is uneven for reducing deposit build-up on said surface.
