The determination of the location of the interface between two fluids, separable by gravity, with respect to a fixed horizontal datum plane. The respective fluids may be any fluids, liquid or gaseous, which do not mix and have specific gravities significantly different from one another. Fluids include granular or particulate solids which are fluidized or handled like fluids. The most common level measurements are, however, between a liquid and a gas or vapor.
