Patent ID: 7201113

Claim:
An animal drinking water apparatus for providing controlled addition of a first aqueous solution having a first concentration of a chemical species at a first flow rate to a second aqueous solution having a second flow rate to provide a diluted first solution of a desired selected concentration of said chemical species as said drinking water, said apparatus comprising first solution sensing means to obtain data on the temperature of said first solution; second solution sensing means to obtain data on said second solution selected from said second flow rate and the temperature of said second solution; positive displacement injection pump means to effect addition of said first solution to said second solution to provide said diluted first solution; and CPU means (i) to receive said data selected from said second flow rate data and temperature data from said second solution sensing means; (ii) to receive said temperature sensing data on said first solution from said first solution sensing means; (iii) to effect algorithmic treatment of said data from said first and second sensing means, to provide pump control data; and (iv) to control said pump means in consequence of said pump control data to effect controlled addition of said first solution to said second solution to provide said diluted first solution of said desired selected concentration of said chemical species as said drinking water, further comprising (a) means for providing a first water flow; (b) means for providing said second solution at said second flow rate; (c) mixing means for effecting the dissolution of said chemical species into said first water flow to produce said first aqueous solution having said first concentration of said chemical species at a pre-selected temperature; (d) heating means for heating said first aqueous solution; and (e) wherein said CPU means further comprises means to effect algorithmic treatment of said temperature data of said first solution; and temperature control means to control said heating means in consequence of said temperature data to provide said pre-determined temperature.
