Abstract
A method of determining the volume or height of fluid in a reservoir is provided. A first burst of focused acoustic energy is used to raise temporarily a protuberance on a free surface of the fluid. A second burst of acoustic energy is directed to the free surface of the fluid. Echoes from the second burst of acoustic energy are detected. The detected echoes are employed to compute the height of the fluid.
