Differential fluid parameter determination
First Claim
Patent Images
1. A method for quantitatively determining a parameter of a fluid having a physical property, said fluid being disposed in a vessel into which flows a first portion of said fluid having a first value of said physical property, and out of which vessel flows a second portion of said fluid having a corresponding second value of said physical property, said method comprising:
- altering the first value of said physical property of the first portion of said fluid;
measuring the difference between the first and second values of said physical property; and
interpreting the difference between the first and second values of said physical property in a manner which provides for quantitatively determining a parameter of said fluid.

15. An apparatus for quantitatively determining a parameter of a fluid having a physical property, said fluid being disposed in a vessel into which flows a first portion of said fluid having a first value of said physical property, and out of which vessel flows a second portion of said fluid having a corresponding second value of said physical property, said apparatus comprising:
-
means for altering the first value of said physical property of the first portion of said fluid; and
means for measuring the difference between the first and second values of said physical property; and
means for interpreting the difference between the first and second values of said physical property to quantitatively determine a parameter of said fluid. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
