Mathematical Model Of A Four-Beam Turbidity Sensor

Fresh water importance is increasing worldwide. The only way to provide the demanded amounts of fresh water is by means of increasing the amounts of processed and purified water. Turbidity measurements are accomplished at all stages of water processing. This paper proposes a mathematical model of a four-beam turbidity sensor. The transmission functions of both the sensor and the measured medium have been analytically described and evaluation of the processes of light transmission and light scattering has been carried out. The availability of a mathematical model of a four-beam turbidity sensor would facilitate its analysis and its construction improvement.
