Simplified instrumentation for ultrasonic measurements to generate and detect ultrasonic pulses in liquids and solids is described. High frequency pulse generator is assembled using integrated circuits (74LS00, 74LS90, 74LS93, 4093, 74121 and 7407), which generates variable frequencies (0.625, 1, 1.25, 2.5, 5 and 10 MHz), having pulse width 2 microseconds to 60 microseconds. The wideband receiver is developed using radio frequency amplifier (IC CA3028), zero-cross detector (LM393), and buffer amplifier (AD 826). The gain and bandwidth of the receiver are 50 dB and 15 MHz respectively. Transit time measurement has been taken on personal computer using analog to digital converter card. The system is found suitable, accurate and versatile for ultrasonic velocity and attenuation measurements.
