ABSTRACT:
A method for determining the solids weight fraction of a slurry especially a coal slurry is described based on a measure of the concentration (wt/wt) of hydrogen in the slurry by neutron transmission or scatter. Accuracy of the method can be improved by combining the neutron measurement with a .gamma.-ray transmission or scatter measurement, and further improved by including a measurement of X-ray scatter or transmission. In the last mentioned case the mineral matter content of the coal in the slurry can also be determined.
