A method of correcting reading of a non-contact solids flow meter measuri ng 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 als o 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 exces s of the actual flow rate. In addition, if the product flow creates dust during t he 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.
