METZ CONNECT – Energy Meter Application Example The Challenge In Germany and Europe, numerous companies are legally required to systematically track and optimize their energy consumption. In addition, some consumers rely on professional energy management even without legal requirements—to reduce energy costs, identify savings potential, and actively contribute to climate protection. Precise energy measurement is the foundation for legally compliant documentation and successful optimization. A manufacturing company operates multiple machines and production lines. To meet legal requirements, make...
