Abstract
A baffle assembly for use in an ultrasonic system for measuring the level of a contained volume of liquid by calculating the density of the liquid by determining the dielectric constant thereof. The baffle assembly is located at the lower end of a stillwell located within the volume of liquid, The assembly includes a pair of concentric sleeves formed of electrically conductive material located to surround the lower end portion of the stillwell. The sleeves are uniformly radially spaced from one another so as to function as a capacitor so that the electrical capacitance between the respective opposed surfaces of the sleeves may be determined.
