Abstract
A sensor for measuring the height of fluid in a vessel, the sensor including a mounting base shaped to be coupled to an exterior surface of a vessel. The sensor further includes a transducer having a pulse source for sending pulses into the vessel and an echo detector for detecting echoes of pulses emitted by the pulse source. The sensor further has a dry couplant located between the transducer and the mounting base, and a processor connected to the transducer for calculating the height of fluid in the vessel based at least in part upon the time elapsed between the pulses sent by the transducer and echoes detected by the echo detector.
