Addressing the need for tighter cost control, several firms will offer new devices for energy monitoring. These can provide sophisticated measures of not just active energy (kwh) but also active and apparent power, reactive power, power factor, phase variables, and more. They can also accept inputs of consumption of natural gas, hot or cold water, steam, and compressed air. One such system, reported last month, is the Compact Power Analyzer from Carlo Gavazzi, Buffalo Grove, Ill. The other is the new EnergyMaster module for the BarcoVision PlantMaster production monitoring (MES) system from BMS-Vision LLC, Charlotte, N.C. It uses a system of consumption meters for machines or groups of machines, which are connected to data units that communicate wirelessly with a server. It can provide history reports that include a Performance Characteristic Line (PCL) of energy consumption vs. production throughput, Specific Energy Consumption (SEC) in kwh/lb, and Cumulative Sum of Deviations (CUSUM) trend reports. (These energy characteristics are explained in recent installments of our Energy Miser series, available at www.ptonline.com.) In addition, Fast Heat Inc., Elmhurst, Ill., will introduce “Smart GRid” technology that provides “energy visibility” to assist management, but no details were available. Meanwhile, Dri-Air Industries, Inc., E. Windsor, Conn., will introduce an energy survey program to help molders evaluate the operating cost of their existing dryers. The customer will be presented with data on power consumption and cost over a time period, as well as dewpoint monitoring of dryer performance over that period.
