An instrument has been developed which measures the solids concentration in slurry pipelines ranging in diameter from 5-150 cm. The operating principle is based on conductance, and in contrast to the gamma densitometer, the instrument does not require a nuclear radiation source. The instrument operates online, is non-intrusive, and provides real-time output. The instrument measures local concentration around the pipe periphery, and the local values are integrated to obtain the area-average concentration. A graphical display shows the variation of concentration from the top of the pipe to the bottom as well as the area-average concentration history. The instrument has been extensively tested in a slurry transport facility at the University of Florida as well as on-line at the Swift Creek phosphate mine in the state of Florida. Excellent performance of the instrument is observed over a wide range of operating conditions.
