Patent ID: 7751050

Claim:
A fluid quality monitoring apparatus, the apparatus comprising: an outer tubular structure having an exterior wall surface and an interior wall surface; an inner tubular structure disposed within a hollow region formed within the outer tubular structure, the inner tubular structure having an exterior wall surface, wherein the inner tubular structure is light permissive; a fluid passageway formed between the interior wall surface of the outer tubular structure and the exterior wall surface of the inner tubular structure for free flowing conveyance of a subject fluid for testing; a photovoltaic material applied to a majority of a circumferential section of either surface of the outer tubular structure; an illumination source assembly comprising an illumination source and a plurality of fiber optic strands, wherein emitting ends of the fiber optic strands are located proximate the inner tubular structure interior wall surface, wherein the fiber optic strands transfer emitted light from the illumination source to the emitting ends and projects the light from the emitting ends, through the subject fluid, and towards the photovoltaic material; and an output conduit providing electrical communication for an electrical output signal from the photovoltaic material to a quality monitoring apparatus.
