- Acoustics provides a fast approach to measure engine displacement. Since it does not use a liquid, it is both clean and dry. Bv using the ideal gas law, and measuring differences in pressure changes, the volume can be determined. As a result, in a matter of seconds the capacity (displacement) of an enclosed volume can be determined within about ±0.1 cm3. This paper discusses the theory and gives some examples, along with applications for measuring capacity. In addition, the technique to measure the volume of a body, previously done with displacement of water, will be discussed.
