摘要： A system (10) for monitoring the flow rate of particulate material entrained within an air stream includes a feed hopper (11) providing a source of the particulate material, and a hose (14) for conveying the particulate material within the air stream. A pump (18) draws the particulate material from the feed hopper (11) and transports the particulate material with the air stream through the hose. A flow meter (27) is associated with the hose and measures the mass flow rate of the particulate material through the hose to provide a first flow indication. A device (28) is associated with the feed hopper and measures the change in weight of the feed hopper over a predetermined interval to provide a second flow indication. A controller corrects the first flow indication from the flow meter according to the second flow indication from the gravimetric device. The flow measurement system provides an accurate and fast responding flow meter by combining the advantages of a fast responding in-line flow meter with the accuracy of a weight measurement system.
