Abstract
Monitoring fluid flow of high temperature materials is required across a wide range of applications. A device for performing flow measurements of high temperature materials includes a resonant chamber having at least one inner surface forming a hollow resonant cavity. A deformable membrane has a first side forming a wall of the hollow resonant cavity, and a second side in contact with an external environment in which the resonant chamber is disposed. A waveguide is physically coupled to the resonant cavity, with the waveguide configured to provide to the resonant chamber a band of wavelengths of radiation.
