The dual X-ray technology reveals a range of data about the organic material on the belt such as moisture, dry mass flow, weight and foreign objects.
Dry mass | The dry fiber mass flow is a very important measurement parameter to achieve a stable digester control. When used together with the moisture content, it is possible to optimize the balance between dry fiber, white liquor and liquids.
Moisture | Whether it is organic material or free water, snow, or ice, the FlowScanner delivers this fundamental property with high accuracy, in an instant.
Weight | The FlowScanner has two X-ray energy sources measuring across the full width of the belt, delivering wet mass flow rates. Together with the moisture measurement, the amount of bone-dry material in the process can be determined.
Foreign objects | Inorganic high density materials, such as metal or rocks, produce different signals on the X-ray detectors. A size limit can be set so that larger objects trigger an alarm for removal whilst smaller items are recorded only for review purposes.
