Abstract

   In this paper we present a Java application used for computing the water level in a pipeline starting from signals which are obtained during experiments. The measurement principle is based on the properties of the ultrasonic wave propagation in the steel-water-steel structures. The signals are formed from echoes of an ultrasonic impulse sent in a steel pipeline with different filling levels. By computing the difference between two echoes we find the time needed by the impulse to leave the transducer, to reach the water surface and then again the transducer. The developed application is a graphical interface that allows the user to load a signal, to analyze it using a detection algorithm and then to display the results.
