Development of a radio frequency surface contour mapping system

摘要

A radio-frequency based system is being developed for imaging the top surface of the contents of vessels used in coal processes including lockhoppers, gasifiers, and mixing chambers. The system will be designed to image a minimum of 25 pixels with a depth resolution of (+-)1 inch over ranges of 4 to 30 feet. The system must tolerate harsh environments as found in coal gasifiers with temperatures up to 1800 F and pressures up to 600 psig. The system will provide both a visual readout of the contour of the upper surface of a vessel's contents via a computer monitor and a data interface to the process control system.
