This paper describes a practical instrument for the measurement of sound velocity in liquids. By analysing the principle, formulas, sensor appli-cation and sound path design, and cliscussing errors caused by temperature variation and inherent delay as well as their amendment and correction meth-ods, precise calculating formulas and digital display methods are introduced. .
