Abstract :
A simple method which does not require calibration with a reference liquid for the determination of attenuation and density of a fluid contained within a thin-walled cell is demonstrated. The method relies on temporally filtering the impulse response of the system to partially deconvolve the transfer function associated with the wall. Experiments are conducted on cells of differing material construction and wall thickness which demonstrate the effectiveness of this method in obtaining accurate near-field measurements of density and attenuation
