Abstract
A method of correcting reading of a non-contact solids flow meter measuring solid particulate flow where the solid particulate product enters the flow tube at one end and flows past a sensor and then exits the flow tube. The sensor for the flow meter is very sensitive and not only can sense particulate flow, but can also pick up system machinery motion such as the rotation of a screw conveyor or other moving machinery parts as product flow and provide a system output reading in excess of the actual flow rate. In addition, if the product flow creates dust during the initial calibration process, and the dust is controlled at the actual installation, the system output reading may indicate a flow rate substantially less than the actual flow. The calibration method of this invention uses the original calibration or performance curves to accurately correct the output readings.
