LPM Comppress Figure 2: Equipment Performance Meter. This image shows a typical equipment performance meter. The example is for a compressor monitoring system, The index monitored is the compressor efficiency ratio (see graph). The graph is a run chart of compressor operations. Efficiency ratio decay is used to predict maintenance requirements. Other data gives average and current operating conditions.
