Abstract Calibration of a modified sing-around ultrasound velocimeter, with ultra-pure water, has been done using sound speed data recommended in the literature for pure water. Empirical calibration parameters were evaluated by a least-squares fitting method and the impact of both the uncertainties in measured quantities and propagation of uncertainties in the calibration parameters and other influence quantities on uncertainties in the calculated sound speed in water have been estimated. Examples are given for calculating the uncertainties of some useful thermodynamic properties derived from ultrasound speed data that are used in important industrial applications such as estimating concentration of solutions and density of binary liquid mixtures.
