摘要

In-line turbidity analyzers have been successfully used for many years to measure the suspended solids and/or emulsions levels in liquid process streams in real time. The technique employed is the measurement of light scattering at various angles from the light source and at various wavelengths. The data from these in-line analyzers has helped to optimize and reduce upsets in industrial processes.rnThis paper gives an overview of the light scattering turbidity techniques used and why certain methods perform best in specific applications. Sensor fouling or coating can be a concern, therefore automatic in-place cleaning will be discussed. Calibration is an integral part of any in-line analyzer; the calibration methods used will be presented and compared. Data from both on-line and off-line turbidity analyzers will be reviewed along with the sample conditioning challenges encountered.
