4.4 High-resolution sound-velocity measuring cell for liquids

The resonator and ultrasonic transmission cells described above are also suitable for determining sound velocity. In the case of resonators, however, two separate measurements are always required, which automatically introduces an error because it cannot be guaranteed that the precise environmental conditions can be reproduced in the second measurement.
