Abstract Details

2010, Master of Science, University of Akron, Electrical Engineering.
Non destructive evaluation techniques have many applications such as flaw and leak detection, location determination, estimation of mechanical and physical properties. One such technique is Ultrasonic testing. The main purpose of the thesis is to transmit data through petroleum using Ultrasonic communication. Although, there are several modulation techniques that can be used to transmit the data, this research work explores one such possible method of communicating through petroleum: Amplitude modulation. A message signal (square wave) with 1 KHz input frequency and an amplitude of 15 volts peak-to-peak has been transmitted through water after being amplitude modulated with a carrier signal of 2 MHz frequency and an amplitude of 20 volts peak-to-peak. The transmitting transducer is excited with a high voltage signal close to its resonating frequency. The signal at the receiving ultrasonic transducer is demodulated using the peak detection circuit to obtain the original message signal but with attenuation. Although the transmission medium used for the research is water, it can be performed with petroleum as well since the attenuation properties are quite similar. A considerable portion of the thesis is devoted to the study of properties of ultrasound, oil and petroleum.
