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, foams and deposits. The level Read More …

A new level-measurement method is presented. It is based on the acoustic resonance of a waveguide. This method can be successfully implemented for fluid-level measurements in industrial plants, where problems of residues, deposits, foams, etc., can be expected. An experimental Read More …

This paper presents concept and design of a miniature liquid level gauge. An experimental level gauge with the measurement range of 5 cm, relative accuracy better than 0.5% and resolution better than 0.1%, has been demonstrated in practice. The proposed Read More …

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 microphone is used as an Read More …
