Abstract
The composition monitor uses a flow driven acoustic resonator whose frequency is simply related to the speed of sound of the gaseous mixture present in the cavity resonator. Because the speed of sound is a function of temperature and composition of mixtures, the oscillator frequency signal may be used to measure the composition and control the process. The aeroacoustic sources have the advantage that they are immune to high pressure and high temperature and are energized by flows leading into or out of reactors. In addition, sound is led to a measurement microphone from the source by a solid rod which isolates it from high pressure and temperature obtaining thereby a robust sensor.
