Abstract
A system for detecting fine liquid, e.g., oil, particles in a gas system having a conduit through which a gas, e.g., hydrogen, air, etc., will flow. The detection system includes a monitor including a high sensitivity photometric sensor, a data acquisition unit and flow and pressure control components to control the pressure and rate of flow of the gas to the monitor. The detection system is arranged to detect the presence of fine liquid particles the gas passing through the conduit and to provide an alert signal representative of the mass count of such particles in response thereto.
