Abstract:
1. A material sampling interface comprising: at least one inlet manifold; at least one pump connected to said inlet manifold, said pump being adapted to pump said material into said inlet manifold; at least one outlet manifold; a plurality of rungs positioned between said inlet manifold and said outlet manifold; a bypass positioned between said inlet manifold and said outlet manifold; and a controller connected to said pump, said rungs and said bypass, wherein each of said rungs includes a reservoir and a plurality of valves, wherein said reservoir includes a sampler inside said reservoir adapted to sample said material, wherein an inlet valve is positioned between each reservoir and said inlet manifold and an outlet valve is positioned between each reservoir and said outlet manifold, and wherein said controller controls said pump, said inlet valve, said outlet value, and said bypass to cause material to flow into and out of said reservoir to allow said sampler to sample said pumped material.
