Determination of local intensity of motion of particles in a gas-solid suspension from separate measurements of mass flow and density involves the error due to covariance of the average of mass flow. The two-dimensional nature of horizontal pipe flow of a suspension under strong influence of gravity was validated by simultaneous measurements of density by fiber optic probes at various gaps and mass flow by electrostatic probes at a horizontal diameter. Flow distributions over the pipe height were determined by traverses with simultaneous measurements of mass flow and density with an electrostatic ball probe and a laser beam at the same location. This provides for direct determination of local velocity, intensity, autocorrelation, length scale of the motion of particles and their diffusivity.
