Abstract
A well tool can include a resizable element that is longitudinally expandable and contractible. The well tool can include a first acoustic sensor unit positioned at a first longitudinal end of the resizable element for receiving a first wireless acoustic signal, waiting for a predefined period of time, and transmitting a second wireless acoustic signal after the predefined period of time has elapsed. The well tool can include a second acoustic sensor unit positioned at a second longitudinal end of the resizable element for transmitting the first wireless acoustic signal at a first time, and receiving the second wireless acoustic signal at a second time. The second acoustic sensor unit can also be positioned for determining a time delay between the first time and the second time, and determining a distance between the first acoustic sensor unit and the second acoustic sensor unit based on the time delay.
