Abstract
A method to determine a piston position in a sample bottle, having steps of providing a transducer near a chamber of the sample bottle, exciting the transducer to provide at least one wave of acoustic energy, propagating the acoustic energy through the chamber to a surface, reflecting the acoustic energy from the surface, receiving the acoustic energy at a receiver, determining a time of flight of the acoustic energy, and calculating the piston position from the time of flight of the acoustic energy.
