Rice Lake Weighing Systems, Rice Lake, Wisconsin, U.S., introduces its BWC-1 bulkweighing controller for precise filling of rail cars, barges or storage bins. The BWC-1 incorporates the latest analog-to-digital technology to provide high-level accuracy. Using a unique mathematical equation to estimate cutoff values, the controller optimizes operation by allowing for head pressure variation in the upper garner. Maximum draft sizes can be configured for individual products, ensuring that the weigh hopper will not be overfilled. The controller uses eight sensor inputs to monitor product-supply hoppers, gate disposition and target vessel product level. Able to weigh up to 100 different products, the bulk weighing controller easily handles large product bases.
