Refer to relevant standards about turbidity measurement and combined with feature of conventional low turbidity measurements,a 90°scattering turbidity on-line sensor is designed,and measuring principle,optical path design,structure design and measurement and control circuit design are introduced. Refer to relevant standard, experimental verification is conducted measurement repeatability is 0. 25%,span drift is 1. 2%,and linearity error is 1. 2%. Experimental results show that the sensor has good measurement repeatability and high measurement precision,especially suit for turbidity monitoring in the occasions of water environment monitoring and water pollution control.
