MEAREG's Ultrasonic sensor technology, meaSONIC®, provides a huge cost savings compared to Beta radiometry or X-Ray (gamma radiometry) basis weight measurement technologies. The meaSONIC® sensor is based on the ultrasonic absorption measurement method. The built-in processor calculates the basis weight in real time regardless of material, color, position and is suitable for paper, metals, plastic, technical fleece, fabrics and many more.
