A compact, rugged and portable measurement cell design for the determination of sound speed in fluids at temperatures up to 250.degree. C. and pressures up to 3,000 psi is described. Swept Frequency Acoustic Interferometry measurement for liquid sound speed determinations in liquids up to 250.degree. C. is of both fundamental interest, as in the case of basic equations of state, and applied interest, such as for characterizing geothermal or petroleum down hole environments. Representative sound speeds for water, as a function of temperature and pressure, are in agreement with an internationally accepted standard for the sound speed of water.
