1. A system for on-line multi-component fluid analysis, wherein the said system comprises:
a first capillary tube in communication with a reference fluid source in a reference fluid flow path; a second capillary tube in fluid communication with a sample fluid source in a sample fluid flow path; a pump in fluid communication with said first capillary tube and said second capillary tube, said reference fluid flow path being in fluid isolation from said sample fluid flow path; a pump fluid supply in communication the pump; a controllable fluid flow regulator disposed between said pump fluid supply and said pump, wherein pumping action of pump fluid through said pump actuates reference fluid through said reference fluid flow path and sample fluid through said sample fluid flow path simultaneously; a first pressure gauge in said reference fluid flow path so as to collect data from said first capillary; a second pressure gauge in said sample fluid flow path so as to collect data from said second capillary; a data acquisition system in communication with said pump, said controllable fluid flow regulator, and first and second pressure gauges; and a computer in communication with said data acquisition system, wherein said computer controls said controllable fluid flow regulator so as to determine rheological behavior of the fluid in terms of Newtonian viscosity and shear rate in real time, wherein said rheological behavior is comprised of absolute viscosity, wherein said data from said first capillary tube is comprised of pressure at discharge of a set amount of reference fluid from said first capillary tube and pumping rate of said pump, and wherein said data from said second capillary tube is comprised of pressure at discharge of a set amount of sample fluid from said second capillary tube and said pumping rate of said pump simultaneous with discharge of said set amount of reference fluid. |
