Invention of a tunable damper for use with an acoustic waveguide in hostile environments

A damper was invented to remove undesirable stress pulses from an acoustic waveguide. The damper was designed to be tunable, and constructed to withstand a corrosive or otherwise hostile environment. It serves to simplify the design and enhance the performance of a water level measurement system, of which the damper and acoustic waveguide are integral parts.

An experimental damper was constructed and applied to an existing level probe and measurement system. The resulting damper, properly tuned, causes acoustic stress pulses which pass into it along the waveguide to be completely attenuated.
