Photoelectric Tube Type Dew-Pointmeter for Measuring of Humidity of Supplied Gas

Abstract

A photoelectric tube type dew-pointmeter was set up to measure continuously aqueous vapor content of supplied gas. In this report, the authors described about the dew-pointmeter and showed some factors affecting the result measured by the apparatus. That is : An appearent dew point of flowing gas rises as a flow rate of gas increases. Kinds and condition of conduits affect an aqueous vapor content of supplied gas. And heating of flowing gas seems to elevate a dew point of it.
