Algorithm for Determining the Dielectric Constant and the Amount of Fuel in Three-Layer Media by Radio-Frequency Monitoring

Resumo

A principle is proposed for constructing a transducer for detecting the position of interfaces between layers, the dielectric constant, and the amount of fuel in three-layer media. Sensor structures in the form of an electromagnetic cavity excited at three characteristic frequencies are developed, along with an algorithm for conversion of primary data from coarse measurements at these frequencies. The transducer provides high measurement accuracy.
