Flow weighers are used for continuous weighing of potatoes and similar products, and for summary of weights recorded. The flow weigher features a flat, vulcanized endless belt in plastic or rubber and a special conveyor designed for optimum precision. The weighing device is protected against overloads, and has its load cell positioned in the conveyor. A pulse transducer is mounted on the tensioning roller to measure exact speed in order to eliminate incorrect readings due to belt sliding. The central control unit with its digital display is located in a special enclosure. Conveyors are available in various dimensions to meet differing capacity requirements.
