In industrial facilities, measured quantities can be divided into two main categories: non- electrical quantities (such as pressure, flow, temperature, etc.) that require conversion into electrical signals through sensors and converters, and electrical quantities (like voltage and current) that are already in the form of electrical signals and do not require conversion. A common requirement for both categories is measurement, collection, visualization, and data distribution accuracy. Modern digital measurement systems improve the accuracy of these measurements and facilitate the straightforward remote transmission of data, along with its visualization and storage for future analysis. This paper focuses on measuring and manipulating values obtained from digital energy meters that operate following EU regulations and are utilized in industrial, administrative, and residential settings. Unfortunately, in many instances, reading and data collection are performed manually at the meter's location, which limits remote access. The paper proposes a system that connects to existing digital meters to solve this issue. This system enables local data transmission to personal computers and allows online remote access via an RF network and an Intranet.
