Publication number: 20210404950Abstract: An optical sensor may be used to measure the concentration of calcium in a water sample, such as a water sample obtained from industrial process water system like a cooling tower system, a boiler water system, or a waste water system. To measure the concentration of calcium, an indicator or reagent may be added to the water sample to form a complex that absorbs light. The absorbance profile of the complex may be non-linear over a range of calcium concentrations. However, the absorbance profile can be linearized to provide calibration coefficients that are subsequently used to determine the concentration of calcium in samples having unknown calcium concentrations. The linearization of the absorbance profile can allow the optical sensor to be calibrated using two solutions. This can reduce the complexity and cost of calibrating the optical sensor, which may otherwise require at least three calibration solutions to capture the non-linear profile of the absorbance curve.Type: ApplicationFiled: June 30, 2021Publication date: December 30, 2021Inventors: Hui Li, Bingzhi Chen, Brandon Davis
