A clamping apparatus for coupling an ultrasonic transducer to a conduit is disclosed. The clamping apparatus comprises a base portion fastened to the conduit and including a bracket for receiving an adapter. The adapter is attached to a housing and allows the housing to be rotated when the adapter is positioned in an upper portion of the bracket, and prevents the housing from being rotated when the adapter is positioned in a lower portion of the bracket. The housing is configured to enclose the ultrasonic transducer except for a housing opening along the bottom of the housing. The ultrasonic transducer extends through the housing opening and is spring biased against the conduit.

A switched capacitor digital-to-analog converter ('DAC') for converting a digital input code to an analog signal comprises a switched capacitor array and a reset switch having a first end and a second end. The digital input code is inputted to the switched capacitor array. The switched capacitor array is connected to a summation node. The first end of the reset switch is connected to the summation node and the second end of the reset switch is connected to a common mode voltage. The reset switch is closed after a plurality of sampling cycles. The analog signal is provided based on a summation voltage at the summation node.

A cable bushing assembly and a method of sealing a cable penetration through a housing are provided. The bushing assembly includes an interior shell, a central cavity and at least one aperture between a first face and a second face. At least one cable passes through the bushing assembly. The bushing assembly also includes an exterior shell at least partially circumscribing the interior shell. A clasp is located between the interior shell and the exterior shell to prevent separation of the exterior shell from the interior shell. Packing material seals the at least one cable within the interior shell. A method of sealing a cable penetration includes providing a housing with an opening, inserting a bushing assembly into the opening, and securing the cable bushing.

A system includes a container assembly comprising a cover threadingly coupled to a container along a threaded interface portion of an interface and a cover lock assembly. The cover lock assembly includes a lock screw configured to selectively move between a cover lock position and a cover release position. The lock screw extends across the interface to resist threaded rotation of the cover relative to the container in the cover lock position, and the lock screw is recessed away from the interface to enable threaded rotation of the cover relative to the container in the cover release position. The cover lock assembly also includes a lock insert configured to block movement of the lock screw from the cover lock position to the cover release position.
