ABSTRACT:
Methods and systems useful for obtaining a representative sample of solid particles from a pneumatically conveyed stream of solid particles. One preferred method and system includes establishing a pneumatic flow of solid particles in a gas stream through a sampling conduit and diverting the steam through a second conduit; isolating an inlet of the sampling conduit from the second conduit substantially simultaneously with the step of diverting the entire stream through the second conduit and emptying material from the isolated sampling conduit, wherein the representative sample comprises the material emptied from the sampling conduit. The outlet end of the sampling conduit may be vented into the second conduit or the atmosphere. The system for accomplishing the method may include a controller for controlling, inter alia, a position of the means for diverting the stream through a second conduit, the means for isolating an inlet sampling conduit, or combinations thereof.
