World Metrology Day is the anniversary of the signing of the Metre Convention in 1875. Every year, on 20 May we will celebrate for this. Because it lays the foundation for the establishment of a globally coordinated measurement system, providing support for scientific discovery and innovation, industrial manufacturing, international trade, and even the improvement of quality of life and global environmental protection.

World Metrology Day 2022，The theme of this year is Metrology in the Digital Era.

With the advent of the digital age, the function of the system has transformed from construction to application, has been upgraded from pure technical thinking to a business philosophy that includes all elements of strategy, culture, management, production, and organization.

In the digital age, data is the most important means of production, not only because data can be used to analyze and drive business on the enterprise side, but more importantly, from a technical point of view, everything based on software is built with data. Data is like today’s bricks, gray, sand, and reinforced concrete. It is a building material. This is a very important feature of the digital age that is different from the past.

This is also the biggest difference from the information age.

In the information age, the digital economy has not yet become the most important economic form and has not reached a high status, but in the digital age, the digital economy will become one of the most important industries.

In this digital age, metrology is everywhere, data is everywhere.

Our smart meters perform two important tasks in the digital era: metering and data transmission.
