Abstract
Apparatus for measuring the bulk density and mass flow rate of pulverized coal entrained in air along a duct 6 comprises beta radiation source means 7, radiation detection means 8 and a shield 9 to intercept direct radiation falling on the detector means which thereby measures the diffuse radiation scattered by the coal particles. That measurement plus a signal indicating linear coal particle speed is fed to a data processor which calculates the bulk density and mass flow rate.
