Abstract

An apparatus for determining a density-compensated liquid level in a vessel containing a mixture of liquid and vapors comprises a temperature sensor which produces a signal that is proportional to the temperature of the mixture; and a processing apparatus (50) that includes one or more pressure sensors (52,54) that allow for a measurement of an operating pressure and a differential pressure between the mixture in athe vessel (30) and a constant reference leg. The processing apparatus further includes an integral microprocessor (56) for calculating the respective gravities of the liquid and vapor portions of the mixture based on the operating pressure, and then computing the density-compensated liquid level in the vessel based on such calculations of specific gravity and the differential pressure.
