ABSTRACT OF DISCLOSURE A flow meter particularly adapted for measuring the mass flow rate of pulverized coal being introduced into large scale power generation boilers. The meter includes a transmitter which generates a pulsed beam of ultrasonic impulses. A receiver is positioned across the flow field from the transmitter and receives the ultrasound pulses. The meter measures the downstream drift of the ultrasound pulses and its attenuation which are related to flow velocity and concentration, respectively. The instrument includes controlling and processing means for automatically adjusting the relationship between transmitter and receiver, and performs numerical analysis routines on the signal outputted from the transmitter to provide a signal related to attenuation and coal concentration.
