The measurement of propagation velocity and density of several liquids is performed in the 15 to 40°C temperature range. Results are compared to tabulated values in the case of distilled water, showing accuracy of 0.07% for the propagation velocity. Density values are compared to those obtained with a pycnometer, showing 0.2% accuracy in density measurement for stabilized temperature and 0.4% under thermal gradient conditions.4137-4144engDensity valueDistilled waterPropagation velocitiesTemperature rangeDensitometersMeteorological instrumentsDensity of liquidsTrabalho apresentado em eventoAcesso aberto2-s2.0-84873818773640533951088320328834403518951670000-0003-4201-56170000-0001-6320-755X
