A flow meter for determining the flow rate or mass of a moving stream of fine particles comprises a guide means for guiding the material to be measured along a predetermined path having an entry end and an exit end. A transducer is operatively associated with one end of the guide means and includes a mechanical column connected between a load cell and the exit end of the guide means. The load cell produces an electrical output signal proportional to the flow rate of the material on the guide means. A means for vibrating the guide means is provided and serves to keep the flow stream moving and wherein the plane of vibration is perpendicular to the plane of measurement, thus eliminating measurement error due to the vibrational forces.
