Ultrasonic Depth Measurement System Sweet

A co-operative project between Kraft Foods Lietuva and Ultrasound Institute
Contract no.: 7452

The objective of the project

To develop a non-contact profile reconstruction technique for automatic measurements of the thickness of a semi liquid chocolate layer at selected points with high accuracy (uncertainty < 0.1mm), when the object moves with an unknown variable velocity.

Ultrasound Institute

The high accuracy automatic ultrasonic depth measurement system was developed, including ultrasonic air-coupled transducers and production quality control software for line operator.
