Patent ID: 7343781

Claim:
A detection system for detecting the presence of fine liquid particles in a gas system, the gas system comprising a compressor or other device which may introduce fine oil particles into a gas and at least a first gas handling device and a second gas handling device, a first gas-carrying conduit connected between the compressor or other device and the first device and a second gas-carrying conduit connected between the first device and the second device, the first and second devices being connected in series downstream of the compressor or other device by the gas-carrying conduits, the first device having a first valve associated with the first device, the second device having a second valve associated with the second device, the compressor or other device being susceptible to introduce fine liquid particles into the first gas-carrying conduit, said detection system comprising a data acquisition unit and at least a first monitor and a second monitor, each of said monitors being arranged for detecting the presence of fine liquid particles in the 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 first gas-carrying conduit, said second monitor being in communication with the interior of the second gas-carrying conduit, said data acquisition unit being arranged to provide at least one output signal concerning the detection of fine liquid particles in the gas system.
