Abstract:
1. Apparatus for testing and analyzing a plurality of stream sources having various flow rates to monitor for an upset condition in one of the stream sources, comprising: (a) a manifold adapted to form a test sample of one or more of the plurality of stream sources; (b) a plurality of sampling devices for sampling the plurality of stream sources, each sampling device being coupled to the manifold to provide a stream sample from one of the stream sources to the manifold; (c) a controller in electronic communication with each of the plurality of sampling devices for providing test samples in the manifold, the controller alternately operating the sampling devices in (1) a sequencing mode in which each test sample is a stream sample from one of the plurality of sampling devices and (2) an averaging mode in which each test sample is representative of an average of the stream samples from the plurality of sampling devices; and (d) an analyzer coupled to the manifold to receive the test samples from the manifold and analyze each test sample to determine the presence of the upset condition.
