In mode 2 and mode 3, the echo window is limited to the time interval between
successive interface echoes (see Figure 13-12 on page 234). The end of the echo
window must be set ahead of the second interface echo to prevent an incorrect
detection, which in turn determines a maximum measurable thickness. In
applications involving mode 2 and mode 3 immersion measurements, the echo
window placement must apply throughout the range of the water paths to be used.
