Abstract:
1. A detection system for detecting the presence of fine liquid particles in a gas system, the gas system comprising fine liquid particles in a gas-carrying conduit, said detection system comprising a first monitor, a data acquisition unit and pressure and flow control means, said first monitor being arranged for detecting the presence of fine liquid particles in a gas by means of light scattering and for providing an output signal to said data acquisition unit in response to the detection of such fine liquid particles, said first monitor being in communication with the interior of the gas-carrying conduit, said pressure and flow control means being arranged to control the pressure and flow rate of the gas in the gas-carrying conduit so that the pressure and flow rate at said first monitor is within a predetermined range, whereupon said data acquisition unit provides at least one output signal indicative of an absolute value change in the mass count of any fine liquid particles in the gas carrying conduit; wherein said pressure and flow control means is arranged to control the flow within a range of about +/−2% for rates in the range of about one to thirty liters per minute, and to control the pressure within a range of +/−10 psig for pressures in the range of about 100 to about 350 psig and about +/−5% of the value in the range about 1 to about 100 psig.
