Resonant decay sensors that determine a parameter based on the decay of acoustic standing waves in a tube. Parameters that can be determined include temperature, pressure, the level of a material in the tube, and the height of a material above an end of the tube. Resonant decay sensors can produce both point level and continuous level sensors. A vibration mount, such as a rubber ring, beneficially isolates an acoustic transducer from the body of the tube.
