  • Optical nitrate sensor compensation algorithm for multiparameter water quality measurement
    Patent number: 10955341
    Abstract: An optical nitrate sensor features a signal processor or signal processing module configured to: receive signaling containing information about a concentration of nitrate dissolved in the water based upon a first UV optical absorbance of light centered at 229 nm, and also containing information about a dissolved organic matter (DOM) sensed in the water based upon a second UV optical absorbance of associated light centered in a range of 250 nm to 275 nm; and determine corresponding signaling containing information about a corrected concentration of nitrate dissolved in the water by compensating the concentration of nitrate for the DOM sensed in the water, based upon the signaling received.
    Type: Grant
