Abstract

The present invention provides a solid flow meter accuracy detection system and method, wherein a discharge device is provided to provide a stable discharge mass flow rate of powder, and the powder passes through a first feeding pipeline provided with a solid flow meter under the action of wind, and then the wind speed is adjusted by an air supply device so that the powder forms a stable pneumatic conveying state in the first feeding pipeline; then the powder mass flow rate detected by the solid flow meter at this time is compared with the powder discharge mass flow rate provided by the discharge device to determine the accuracy of the solid flow meter. In the present invention, the discharge device uses a magnetic coupling to improve the measurement accuracy of the powder discharge mass flow rate of the discharge device; at the same time, when the powder is in a stable pneumatic conveying state, it can be fully measured by the solid flow meter, thereby improving the detection accuracy of the solid flow meter, thereby achieving the purpose of accurately measuring the accuracy of the solid flow meter, and the detection device is also simpler.
