The measurement technology and metrology, as one of the structural components of the entire modern economy, is involved in the "Fourth Industrial Revolution", better known as "Industry 4.0". Advances in the technologies for digital information generation, transmission, processing and storage (the processes commonly referred to as "digitalization") open up new opportunities for developers of measuring equipment and metrologists. On the other hand, the introduction and development of "smart" systems and digital models requires direct participation of instrument makers and metrologists in the creation of "intelligent" sensors and the development of fundamentally new approaches to ensure the metrological reliability of instruments and measurement techniques, including in the field of non-destructive testing and condition monitoring.
