ABSTRACT:
The sensor system monitors solutes in a liquid stream by analyzing the amount of light absorbed in a liquid in a particular wavelength band. The sensor system is arranged for selectability of the type of fiber used for transmission and adjustability of the liquid gap length in the liquid so that individual installations can be arranged with optimum characteristics for sensing particular chemical species in solution by absorption spectroscopy.
