According to deviation of measurement when most of flowing turbidimeters are used to detect low turbidity water, a new usage of sensor structure is proposed through theoretical analysis and guidance. To meet the needs of the new usage, the constant current source circuit we designed shows its advantage. Considering light intensity changes slightly in low turbidity water, 0-calibration circuit is added to the system to increase the distinctiveness. Chebyshev digital filter is used to filter the noise of sample, so that precision of turbidimeter in low turbidity water is guaranteed. Experiments prove that circuits we designed and Chebyshev digital filter show excellent steady-state characters and a quick response, so a new solution of how to detect low turbidity water is provided.
