Abstract

This paper describes a non-contact ultrasound system that has been used to measure liquid level in beverage containers at rates of up to 20 per second. The system is both a more accurate and environmentally friendly alternative to the existing gamma-ray based inspection systems. A viable non- contact on-line ultrasonic technique is demonstrated which has potential applications outside the packaging industry.
