US Patent 7913576 Flow scale with basket feature

A flow scale apparatus includes a substantially vertical flow path along which material can flow, a plurality of spreader baffles substantially aligned horizontally and positioned in the flow path, a plurality of basket baffles located downstream from the spreader baffles in the flow path and substantially aligned horizontally, and a sensor. The basket baffles are secured together and configured to be displaceable such that portions of the material in the flow path contact each of the basket baffles to displace the basket baffles relative to the spreader baffles as a function of a weight of the material in the flow path. The sensor is configured for sensing displacement of the basket baffles and generating an output signal.
