Abstract
A sonic transducer shroud is shaped to present an inclined surface to rising bubbles and other matter during water treatment. Attached to the face of the sonic transducer, the shroud prevents the bubbles and other matter from being trapped on the transducer measurement surface and subsequently interfering with echo reception. The shroud has acoustic properties that are matched to the water such that the shroud is substantially acoustically transparent.
