Abstract
Abstract A CONTINUOUS SAMPLE OF A SLURRY FLOW TO BE ANALYZED IS OBTAINED BY CONTINUOUSLY SWINGING THE SLURRY FLOW BACK AND FORTH IN ORDER TO CHANGE THE DIRECTION OF THE SLURRY FLOW SO THAT THE SLURRY FLOW ONLY MOMENTARILY HITS A SAMPLING FUNNEL. THE PORTION OF THE SLURRY FLOW PASSING INTO AND THROUGH THE SAMPLING FUNNEL INTO A SAMPLE FEEDER FOR ANALYSIS IS THE SAMPLE FLOW. THE LEVEL OF THE SAMPLE FLOW IS MAINTAINED CONSTANT WITHIN THE SAMPLE FEEDER BY AUTOMATICALLY REGULATING THE OPENING OF THE INLET PORT OF THE SAMPLING FUNNEL BY SENSING THE LEVEL IN THE SAMPLE FEEDER.
