ABSTRACT:
A process for making a volumetric determination of the quantity of a fluid, such as a liquid, by evaluation of a small sample of that fluid. The method comprises labeling microspheres with a non-radioactive substance and introducing the labeled microspheres into a body of fluid for which a determination is to be made. The microspheres are allowed to disperse in the body of fluid. Thereafter, a sample of the fluid which is of know or measurable volume, is selected. The number of microspheres present in the sample is then determined, from which a calculation of the volumetric measurement of the fluid may be made. The process is also adaptable to measuring the flow rate of a moving stream of fluid, since volume is one of the parameters of flow rate, and is also adaptable to determine the percentages of fluid components present in a mixture thereof.
