The frequency signals are assigned to corresponding turbidity units and solid
matter concentrations, and appear in the display.
Principle of 90° scattered beam Measurement:
I
= Intensity of transmitted light
0
I
= Intensity of scattered light
S
A = Geometrical factor
C = Concentration
f(α)= Angle correlation
P = Particle
