description An apparatus for measuring tubidity of a liquid has a tubular lens of transparent material with an aperture for receiving the liquid. First and second first light emitters are positioned adjacent the tubular lens to produce two beams of light each diverging at a predefined angle and impinging the tubular lens. The tubular lens refracts the diverging beams of light from the two light emitters into separate collimated beams within the aperture. A first light detector positioned adjacent the tubular lens diametrically opposite to the first light emitter and a second light detector positioned diametrically opposite to the first light emitter and a second light detector positioned diametrically opposite to the second light emitter. Each light detector produces a signal indicating an intensity of light received from within the tubular lens and the signals are process to derive a turbidity measurement.
