Abstract
In accordance with presently disclosed embodiments, systems and methods for determining the amount of bulk material being choke-fed into an inlet of a blender from one or more bulk material containers placed on a support structure are disclosed. The system includes sensors placed on the support structure beneath the one or more containers for determining the amount of bulk material contained within the container at any given time. By monitoring the change in the mass of the material in the containers overtime the amount of material being fed into the blender can be determined. The material is metered into a mixer within the blender using a metering mechanism, such as a sand screw, which supplies a fixed capacity of bulk material into the blender. The ability to precisely measure the amount of bulk material being choke-fed into the blender enables operators to calibrate the sand screw continuously.
