ABSTRACT:
Methods and apparatus for determining water content of gases and vapors. The primary sensing device is a fluidic oscillator through which a sample of gas is passed. It is primarily useful in systems where the moisture content is large and there is a small difference between the molecular weight of water and the average molecular weight of the other components of the gas (or vapor) or systems where there is a large difference between the molecular weight of water and the average molecular weight of the other components.
