An instrument has been developed that 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 on - line, 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 an experimental slurry transport facility as well as on - line at the Swift Creek phosphate mine in the state of Florida. When compared with a quick - closing valve measuring technique, the mean deviation of solids concentration measured with the conductance based instrument is 0.81 percent based on mass.
