The speed of sound propagation in the oil products is a physical characteristic in relation with their density. Its measurement permits the identification of the different products which are following one another in the pipelines.

Ø = internal diameter of the pipe
T = speed propagation of the acoustic signal in the liquid

• this measurement is made thanks to an external probe
• the cut off the acoustic beam by spheres or pigs is also detected
• in some cases, a correction in pressure and temperature can be necessary
