Abstract
Technologies are described herein for wirelessly measuring liquid quantity in an enclosure. According to various aspects, an incident electromagnetic wave is transmitted within a conductive enclosure. One or more rebound electromagnetic waves that correspond to the incident electromagnetic wave are received. Using the rebound electromagnetic waves, a transfer function of the rebound electromagnetic waves is measured and a quantity of liquid stored in the enclosure is calculated based on the measured transfer function.
