A mobile agricultural sprayer includes a chemical tank that holds a chemicalfluid to besprayed at a worksite and a rinse fluid tank that holds rinse fluid. Themobile agricultural sprayeralso includes a first sensor coupled to the rinse fluid tank configured todetect a characteristic ofthe rinse fluid within the rinse fluid tank, and, generate a first sensorsignal indicative of thecharacteristic of the rinse fluid. The sprayer also includes a distributionsystem, including a fluidicpathway and a nozzle, configured to pump the rinse fluid from the rinse fluidtank along the fluidicpathway through the nozzle of the sprayer. The sprayer also includes a secondsensor coupled tothe fluidic pathway configured to detect a characteristic of the fluid withinthe fluidic pathway,and generate a second sensor signal indicative of the characteristic. Thesprayer also includes aresidue detection system configured to receive the first and second sensorsignals and, based onthe received sensor signals, determine a concentration of residue within thefluidic pathway.
