Abstract : A method is described in which the dye-dilution curve (including recirculation) is integrated electronically. The integral is recorded separately and simultaneously with the dye-dilution curve. As the primary dilution curve exponentially approaches zero, its integral exponentially approaches a final value. This final value of the integral is the area under the dilution curve. With recirculation, the integral exceeds this true final value. By sampling the dilution curve before recirculation, information is obtained which can be used to graphically determine the final value of the integral curve. (Author)
