Abstract: A method and apparatus for sensing boundaries between materials are provided. The method for sensing boundaries between materials comprises the steps of: fixing sensing modules in place; transmitting and receiving radio frequency signals; and analyzing radio frequency signals. The method enables real-time detection of positions of the boundaries between materials and handling and monitoring of changes in the boundary positions. The apparatus for sensing boundaries between materials comprises at least two sensing modules, or a radio frequency transmitting unit and a plurality of radio frequency signals receiving unit, or a plurality of radio frequency transmitting unit and a radio frequency signals receiving unit. The radio frequency signals are transmitted, received and analyzed by the radio frequency transmitting unit and the radio frequency signals receiving unit to determine the boundary positions and changes therein.

Abstract: A liquid level monitoring system includes: a hardware unit with a tube to extend through a surface of a liquid; a processor unit generating control signals that respectively correspond to target frequencies; a sound generator unit generating, respectively based on the control signals, incident sound waves that transmit in the tube and that are reflected by the surface of the liquid to respectively form reflected sound waves; and a sensor unit for sensing the reflected sound waves to respectively generate feedback signals. The processor unit determines a maximum amplitude frequency based on the feedback signals, and calculates a level of the surface of the liquid based on the maximum amplitude frequency and a length of the tube.
