Title: Acoustic range finder for monitoring level of material
Inventor: STOCKLEY STEPHEN RICHARD
IPC: G01S15/88
Filed: 1989-03-30
Abstract: In an acoustic range finding system, such as may be used for monitoring the level of particulate solids or liquids, a first pulse of high frequency sound is transmitted, a first echo is received in response to the first pulse from an environment in which the system is to be used, and a mask is stored the profile of which represents the variation of the first echo with time (Fig 2). A second pulse of high frequency sound is transmitted subsequent to the first pulse and a second echo is received, the echo being reflected from the surface of material whose level it is desired to detect, and is converted into a return echo profile (1-5, Fig 1). The mask profile is subtracted from the return echo profile to isolate a true echo profile (Fig 3) representative of the surface of material and the true echo (4) is extracted from the true echo profile. The mark profile may be adapted to environmental changes, e.g. temperature. <IMAGE>
