Abstract
A system and method are provided for quantifying a degree of discontinuity of material flow from a meter roller. In an exemplary embodiment, flowable particulate material is fed into a meter roller. The meter roller is then rotated one revolution, and the output from the meter roller is collected and measured. Next, the meter roller is rotated one revolution in discrete increments, each increment having a substantially equal rotational angle. The output from the meter roller is then collected and measured for each increment. Finally, the measurement for each increment is compared to the measurement for the one revolution to determine a statistical parameter indicative of flow rate discontinuity.
