ABSTRACT:
Apparatus for measuring the level of a substance in a container of substantial depth which is practical, efficient, and rugged. Sonic or acoustic waves are transmitted through relatively sonic-wave propagating members, from an emitter member immersed in the substance whose level is to be determined to a collector also immersed in that substance. For this purpose, a sonic generator applies waves to an emitter portion of the wave-propagating means, and a collector portion of the wave-propagating means collects such emitted waves and applies them to a detecting means for producing indications of the level of the substance. The detecting means provide such indications on the basis of the relationship between the emitted and collected waves. The emitter and collector are each in the form of a rigid member capable of longitudinal wave propagations and are of substantially U-shaped horizontal cross-section. The emitter and collector members are affixed to one another and to the container at the mode point of the members, and the means for applying and for detecting the waves are connected to the emitter and collector at the top ends thereof.
