SYSTEM FOR MEASURING MATERIALS IN A VESSEL

摘要

The present invention is directed to a system for measuring physical characteristics of a plurality of materials having boundaries between them which are stored in a vessel having predetermined physical dimensions, which includes a transmitter capable of transmitting a beam of energy at a predetermined wavelength into the plurality of materials in the vessel, the beam of energy generating backscatter from a plurality of the boundaries; a receiver capable of detecting this backscatter; and control circuitry capable of determining the travel time of the beam through a plurality of the plurality of materials based upon the backscatter, and of determining the physical characteristics of the plurality of materials based upon the travel time of the beam and the physical dimensions of the vessel.
