As part of the 8th Spanish Metrology Congress, in which PAYPER will participate this year, we interviewed Salustiano Ruiz González, Director of the Division of Energy Quantities, Environment, and Health at the Spanish Metrology Center (CEM), to discuss the current challenges facing metrology as applied to industry and its role in weighing systems. A conversation about accuracy, reliability, and traceability, but also about digitization, automation, and the importance of integrating metrology from the equipment design stage.
