Abstract
A system for detecting the level of fluid in a fluid containing vessel. The system includes a device for applying energy to a selected location on the vessel. A sensor in proximity to the location detects the energy level at the location during first and second intervals. A memory device stores data representative of the energy detected by the sensor at each interval, and a logic circuit compares the amount of energy of the first interval to that of the second. Data corresponding to the level of fluid in the vessel may be displayed locally or signaled to remote data receiving and display devices, as appropriate.
