    • An apparatus and method for aiming an ultrasonic transducer is disclosed. A tubular member having an axial bore with the transducer extending therein has an upper section, and a lower section with a threaded outer surface and an inner receiving surface. A ferrule assembly includes a compression nut mating with the threaded surface, and a ferrule biased by the compression nut against the receiving surface to form a waterproof seal with the transducer. A collar having a first annular section is detachably mounted coaxially on the tubular member. The first annular section extending to a second annular section having cut-outs suitable for providing access to manipulate the compression nut. The second annular section extending to a third annular section having a positioning members facing a section of the transducer extending from the tubular member.
    • 公开了一种用于瞄准超声波换能器的装置和方法。 具有其中延伸有换能器的轴向孔的管状构件具有上部部分和具有螺纹外表面和内部接纳表面的下部部分。 套圈组件包括与螺纹表面配合的压缩螺母,以及由压缩螺母抵靠接收表面偏置的套圈,以与换能器形成防水密封。 具有第一环形部分的套环可同轴地可拆卸地安装在管状构件上。 第一环形部分延伸到具有适于提供进入以操纵压缩螺母的切口的第二环形部分。 第二环形部分延伸到第三环形部分,其具有面向从管状部件延伸的换能器的部分的定位部件。
