Abstract:

The turbidity of water is one of primary indexes for water quality measurement. Existing main methods for measuring turbidity include scattering method and transmission method. The scattering method is effective for the measurement of low turbidity. Conversely, the transmission method is only suitable for the measurement of high turbidity. In this work, scattering method, transmission method and ratio method are integrated, an on-line turbidity sensor is presented. According to ISO7027 international standards, the sensor’s layout of optical path structure is realized. The detectors are laid in the direction of light source 0 degrees and 90 degrees respectively. Furthermore, the influences of temperature and light on the sensor precision are considered. Least squares support vector machine is introduced to model the turbidity sensor. The experimental results show that this method has much higher precision than the classic methods.
