On-line measurement of fluid density using ultrasonic techniques

The possible use of ultrasonic techniques for the measurement of density for water and sulphuric acid is investigated. The relation of density, speed and acoustic impedance with temperature is determined. In an experiment, the relation between the speed of sound in H/sub 2/SO/sub 4/ and the specific gravity of H/sub 2/SO/sub 4/ was examined. The results obtained matched those of the literature.<
