The most popular and effective technique for ultrasonic velocity measurements is the pulse technique. In the present work, a computer based single-pulse sender/receiver technique is designed in the laboratory using indigenous components and a PCL-812 ADC card. A program written in C controls the pulse generation, detection and travel time measurement. An r.f. burst of 2 MHz of 5μS width is obtained from the ADC card. This pulse is amplified and sent to the transmitting transducer. The received pulse is detected and processed by the ADC card for determining the travel time and displays the ultrasonic velocity of propagation in the system on the computer screen. The system developed in the laboratory has been tested for the ultrasonic velocity measurements in different standard liquids. It has been found that the ultrasonic velocity measurements carried out using the above system matches well with those reported in the literature.

Abstract


The most popular and effective technique for ultrasonic velocity measurements is the pulse technique. In the present work, a computer based single-pulse sender/receiver technique is designed in the laboratory using indigenous components and a PCL-812 ADC card. A program written in C controls the pulse generation, detection and travel time measurement. An r.f. burst of 2 MHz of 5μS width is obtained from the ADC card. This pulse is amplified and sent to the transmitting transducer. The received pulse is detected and processed by the ADC card for determining the travel time and displays the ultrasonic velocity of propagation in the system on the computer screen. The system developed in the laboratory has been tested for the ultrasonic velocity measurements in different standard liquids. It has been found that the ultrasonic velocity measurements carried out using the above system matches well with those reported in the literature.
