    Abstract: The invention relates to monitoring equipment for smoke and/or fine particle emissions from fossil fuel systems, of the type where a beam of visible light is passed across a flue from a light source to a detector, a difference in the light intensity received by the detector from the known intensity of the source indicating absorption of light by smoke and/or fine particles in the flue, and the degree of difference indicating the level of smoke and/or fine particles. The objective of the invention is to provide monitoring equipment of the above type, of simpler, lower cost, more robust nature than has hitherto been provided. This objective is met by a construction comprising two units (1, 2) for location to opposite sides of a flue or chimney each unit comprising a light source, (L₁, L₂) a lens (4) and a light detector (D₁, D₂), the light from the light source of each said unit being directed by its lens across the flue or chimney in a divergence path, to be gathered by the lens of the opposite unit and directed to the detector in the opposite unit, the outputs from the detectors of each unit being combined to provide a reading of the degree of smoke and/or fine particulate material existing in the flue or chimney.

    Abstract: The present invention relates to an optical flow cell (1) for a measuring device, having an input light guide with a light exit surface, an output light guide with a light entrance surface, said input light guide and output light guide being integrated with a holder (30) to form optical flow cell (1), and wherein the holder (30) extends along a first axis (A) and has a through hole (31) for receiving a flow of a sample fluid, said through hole (31) being transversal to said first axis (A), and the input light guide and output light guide further are arranged in said holder (30) so that the light exit surface and the light entrance surface extend into said through hole (31) and are arranged to be in optical alignment with each other and at a first distance from each other. The invention also relates to a measuring device having at least one optical flow cell (1).
