<p>A monitor (18 in Fig. 2) for detecting the presence of particles in an effluent fluid, which particles emit fluorescent light upon irradiation. As used to monitor ion exchange resin fines in effluent liquid in a steam power plant, there is a probe arrangement (26, 30 in Fig. 2; 26 min 56 in Fig. 3; 56 in Fig. 4) to inject fluorescence-stimulating light into a volume (46 in Fig. 2) of the effluent liquid. A detector arrangement (30, 32, 34, 36 in Fig. 2; 56, 32 min , 72, 74, 76 in Fig. 3) is disposed to receive emitted fluorescent light from any particles in the effluent, and an arrangement (40, 44 in Fig. 2; 108, 110, 112, 114, 116, 118, 120, 82, 80, 78, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106 in Fig. 3) actuatable by said detector arrangement (30, 32, 34, 36 in Fig. 2; 56, 32 min , 72, 74, 76 in Fig. 3) for generating a signal to indicate the presence of particles in the effluent. </p> |
