Abstract

A system for managing stratified liquids in a storage tank includes a variable height, in-tank transducer, configured to identify liquid layers of differing and to indicate an elevation of the liquid layers, a motorized drive unit for adjusting an orifice to intercept a selected layer, wireless dada transmission technology, and software to facilitate remote operation of the system.
