Abstract
Systems and methods for measuring the level of a plurality of phases of a conductive or semi-conductive mixture in a vessel. The systems and method include a vessel configured to hold the mixture, a plurality of antennas configured to transmit electromagnetic and/or eddy current signals into the mixture to impinge upon the plurality of phases and to receive corresponding signals reflected from the plurality of phases, a transmitter module configured to generate electromagnetic and/or eddy current signals in communication with the plurality of antennas, a receiver module configured to receive electromagnetic and/or eddy current signals in communication with the plurality of antennas, a control module in communication with the transmitter module and the receiver module configured to control their operation, and a signal analysis module in communication with the receiver module configured to process the reflected signals to determine the levels of the plurality of phases within the vessel.
