Speed of Sound and Density Measurement Brochure

The speed of sound as it travels through a process fluid is used in fluid flow calculations. Process simulation, pressure relief system design, and PRV stability assessments all require accurate flow prediction. The liquid speed of sound and density are two of the properties critical to these calculations, as well as other thermodynamic properties that can be estimated from them. Why measure? Most applications rely on estimation of the liquid speed of sound through a given liquid. These calculations are dependent on a number of properties of the liquid and process conditions, which all have their own associated uncertainties. Measuring the liquid speed of sound directly reduces these uncertainties, allowing for more accurate calculations to be performed.
