Manifold ::   
      Selection of 2, 3, and 4 flow tube configurations offers you the choice 
      of 
no manifold, 
manifold 
      at the top (outlet) or 
manifold at the bottom 
      (inlet).
      
      The 
no manifold option offers isolated parallel 
      channels for flow measurement and control.
      
      Selecting 
manifold at the top (outlet), allows 
      for independent fluid inputs and a single common exhaust.
      
      Selecting 
manifold at the bottom (inlet), provides 
      for a single common fluid input and multiple isolated outputs.
