According to a study from London, the United Kingdom, "A sensor, based on a small cylindrical acoustic resonator that may be suitable for measuring the speed of sound in natural and other process gases under pipeline conditions is described. The resonator is physically robust and requires minimal calibration."
"The speed of sound is obtained from the resonance frequency of a single longitudinal mode of oscillation that is isolated in the frequency spectrum of the cavity and can therefore be located and measured automatically. The design and acoustic model of the sensor are discussed. The performance of a prototype device was validated by means of measurements on ...
