Abstract
Apparatus is provided for precisely measuring the weight of even large amounts of feed stored in bulk feed storage bins. This apparatus includes a number of electrical load cells supported upon a foundation. The weight of the bulk feed bins and any feed contained therein is, in turn, supported upon the load cells by bin support legs. If desired, an interconnecting platform can be provided to support a number of feed bins and their legs upon several cells. In response to weight-induced deformation of a load cell element, electrical signals are transmitted to electrical processing circuitry. This circuitry can provide a display of the weight of feed remaining in the bin, the number of feedings remaining in the bin at a given weight increment of feed, the presence or absence of a minimal amount of feed within the bin, and other data.
