摘要:
Method and apparatus for quantitatively determining a degree of recirculalion flow in a vessel of a fluid by altering the electrical conductivity of the fluid, sensing the difference in electromagnetic field after the fluid is altered, and integrating the sensed difference over a period of time including any time of potential recirculation of any altered conductivity fluid.
