Abstract
A sample fluid stream passes through a molecular sieve in which moisture is adsorbed in direct proportion to the moisture in the fluid stream. Fast neutrons beamed through the sieve interact with the hydrogen nuclei in the accumulated water. The resulting slow neutrons are detected to produce an output indicative of the percentage of moisture in the fluid stream.
Claims10
A system for measuring trace moisture in a fluid stream, comprising
- moisture-adsorbent means for accumulating moisture to an equilibrium point proportional to moisture content of said fluid stream,
- means for continuously directing at least a representative portion of said fluid stream through said moisture-adsorbent means,
- means for irradiating said moisture-adsorbent means with fast neutrons, and
- means for detecting slow neutrons coming from said moisture-adsorbent means indicative of interaction with hydrogen nuclei.
