It has become increasingly important for industry to monitor and control energy usage, not only to reduce costs, but also to reduce the environmental footprint of their manufacturing facilities. Mill information systems provide easy access to live and historical data that can be used as the basis for enhanced decision making at both operational and managerial levels, leading to more efficient energy utilization. However, mill steam flows are routinely found to be inaccurate due to the inherent limitations of today’s measurement instrument technologies and sometimes less than optimal maintenance practices. These problems hinder any evaluation or audit of the process, and can invalidate process decisions that are meant to reduce energy usage.
