An ultrasonic interferometer for the study of liquids in the frequency range 0.1-1.5 GHz has been designed and constructed. The apparatus is robust, simple to operate and, apart from the crystals and their holders, uses standard components. An accuracy of +or-3% in absorption and of +or-1% in velocity has been achieved in measurements of water and cyclohexane.
