Ultrasonic field of level sensors measurement
Hlavatý, Radek ; Fialka, Jiří (referee) ; Beneš, Petr (advisor)
The paper deals with the description of the ultrasonic field around the piezoelectric sensors. The theoretical part serves as an overview for the understanding the ultrasound problematics. More closely studied is the phenomenon of ultrasound wave attenuation. At the end of the theoretical part, three different methods of field measuring were selected and described. The practical part of this work is a more detailed description of the whole measuring system available in the Continental laboratory, that has been put into operation. The system uses a reflection method to measure the ultrasonic field. Automated way of data processing in the form of a script in Python and a macro in Excel was designed. Uncertainties were determined by the test measurements, so was the repeatability of the measured results, that correspond to the physical theory.
