The mixture of coal and water, called slurry, flows through a line (1). A portion of the slurry is drawn off through a line (3) having a valve (7), and is provided to sensing device (10). Water is provided through a line (14) having a valve (16) to flow into a pipe (3). The sensing device (10) utilises low resolution nuclear magnetic resonance techniques in sensing properties of either the slurry or the water and provides a signal S corresp. to percent of hydrogen in the water in the sample. Hydrogen associated with liquids, such as water, can be sensed by low resolution nuclear magnetic resonance, whereas hydrogen in solids, such as coal, is not. The water in line (14) should come from the same source as the water used in preparing the slurry, esp. if the water contains significant quantities of soluble hydrogen containing materials, such as ammonia or formaltis.
