Abstract
A flow rate meter is provided for measuring the flow rate of particulate material being conveyed in a fluid stream along a tubular member. The apparatus includes a throat portion in the tubular member which has a length sufficient to accomplish a pressure drop adequate for accurate particulate material flow rate measurement in the conveying of particulate material in a fluid stream through the throat. The pressure drop is measured across the throat and the measured pressure drop is correlated with the particulate material flow rate. There can be provided converging and diverging tubular sections on opposite sides of the throat to form a venturi. One or more of the flow rate meters can be used in the control of a particulate material blending system. A fluid flow rate measuring means can be used in conjunction with the flow rate meter to provide a signal representative of the difference between the flow rate of particulate material and fluid and the flow rate of the fluid alone, i.e., the flow rate of particulate material alone.
