A fluid quality sensor system comprising a light source, a first light sensitive element disposed at a distance from the light source, forming a gap having dimensions suitable for permitting a fluid to flow therebetween, and aligned with the light source to receive light transmitted by the light source through the fluid, a second light sensitive element disposed perpendicular to a midpoint of a light path between the light source and the first light sensitive element, and a third light sensitive element disposed so as to form an acute angle at the midpoint with the light source.
