A device for measuring the concentration of suspended particles in which there is provided a pipeline wherein the suspended particles are transported pneumatically, with the pipeline being equipped with an element for introduction of these particles. An additional pipeline is located relatively to the principal pipeline so that one of its ends, being the outlet end with respect to the direction of flow of the carrier fluid, is disposed in the region of velocity stabilization of the suspended particles on the measuring portion confined by this region and the element for introduction of particles, and the other end is located outside the said measuring portion in the region free of particles transported in suspension. The principal pipeline contains a parametric converter of the parameter characterizing the mass flow rate of carrier fluid, and the additional pipeline in which only the carrier fluid flows contains a parametric converter, characterizing the mass flow rate of suspended particles, with the magnitude of the signals from the parametric converters being used to determine the concentration of the suspended particles.
