A new device for continuous measurements of a solid mass flow in circulating fluidized beds has been proposed. The solid mass flow meter consists of a cone and a moving scoop. Since it does not have any valves or throttles it does not disturb the gas flow through the CFB loop, which may interfere the solid circulation rate. A mathematical model of scoop motion was solved numerically to make clear its characteristics. A simple analytical solution was provided in order to determine the limiting conditions of the scoop motion. The performance of the device was tested with a 0.2-m-i.d. circulating fluidized bed for various powders (ZnO, FCC, CaCO3, and SiO2) belonging to the Geldart groups A, B and C. The device performed well for all the solids tested over the range of solid mass flow rates of 0–0.942 kg/s, i.e. corresponding to 0 < Gs < 30 kg/(m2·s) for the CFB apparatus used in the present study.
