The Use of One-Dimensional Acoustical Gas Resonator for Fluid Level Measurements
A new level measurement method based on the onedimensional (1-D) acoustics gas resonator is presented. The proposed method has been investigated in detail, and experimental gauges have been built and tested under artificially induced residues,…

An electrically passive fluid level gauge based on an acoustic resonator
This paper describes a novel electrically passive fluid level gauge. It is based on a one-dimensional low-frequency acoustic gas resonator. The acoustical power is delivered to the resonator an the acoustic waveguide and a fibre-optic…
