Method for improving measurement accuracy of multilayer environment levels using time domain reflectometry

Abstract

The authors propose the solution allowing to determine the structure and the layers parameters of the multiphase liquid in real-time mode and thereby to increase the measurement precision. The method is based on using the periodic controllable loads in the measuring probe construction, which can change their own parameters at the required time moment. In the paper a description of the mathematic model of the proposed solution is presented; an algorithm for determination of the layers parameters of the multiphase liquid is proposed; the calculation example of the model multiphase liquid parameters using the proposed algorithm is shown. Also the comparison of the precision of the proposed and standard approaches is presented.
