Description :
The relationships between the sediment concentration in flowing water and the output of capacitance sensor, as affected by temperature, flow velocity, soil types and salt contents were experimentally investigated with 2 types of capacitance sensors. A loam and a sandy soil with sediment concentration up to 70% were studied. The results showed that suspended sediment concentrations, over a wide range, were linearly correlated with the outputs of capacitance sensors. The results suggest that capacitance sensors may be used for sediment concentration measurement of flowing water.
