ABSTRACT:
A batch weighing apparatus for receiving a flow of material such as feedstuff and discharging the material in successive weight determined portions is provided with a dischargeable weighing container and a real weighing system. The weighing system is used both for causing the material flow to stop, when the container has received, approximately, a predetermined weight of material, and to thereafter weigh the material portion with high accuracy. The material flow is not restarted until the container has been emptied. For high accuracy the weighing results are differential, the container being weighed both before and after emptying. A simple and cheap electronic weighing system of high accuracy contributes to a low cost apparatus, which is then an advantageous alternative to the more primitive traditional batch weighing apparatus.
