A flowmeter particularly adapted for measuring the mass flow rate of a mixture of pulverized coal and air. An orifice flowmeter is located in a conduit carrying the mixture, and a reaction mass flowmeter is connected to the conduit either upstream or downstream of the orifice flowmeter. The reaction mass flowmeter includes inner and outer elbows with the inner elbow fixed at one end and free at the other, with a load cell mounted thereon to measure the reaction force caused by the change of direction of the mixture as it transits the elbow. |
