Measurement Of Levels Of Liquids Or Fluent Solid Materials
(AREA)
Abstract
The invention relates to measurement of level of liquid media by acoustic method. The method includes emission, normally to surface of liquid, of sampling signal, reception of signal reflected from the boundary of media separation, and measurement of time interval. The sampling and the reflected signals are canalized in waveguide section as long acoustic waves, those signals are received sequentially in two (the first and the second) reception points, those are placed at fixed distance one from another below the level of radiation point and out of the volume of waveguide section, under condition that the lower (second) reception point is placed above the maximal liquid level allowed.
