Method and apparatus for measurement of ice thickness employing ultra- sonic pulse echo technique

摘要

Method and apparatus for measurement of ice thickness employing ultra- sonic pulse echo technique, wherein an ultra-sonic pulse is emitted from a transducer at the ice-accreting surface of a structure, the pulse is reflected at the periphery of the accreted ice and the reflection is detected. The time delay is calibrated and related to ice thickness and accretion rate.
