Fluke Corp. demonstrated its 1730 three-phase electrical energy logger. The compact energy logger conducts key measurements of voltage, current, power, and power factor to identify areas of energy waste. All measured values are logged automatically and can be reviewed during logging. Common setup errors are rectified through re-engineered cables, digital check and auto-correct of all connections, and an on-screen wizard for interval setup. It has a high safety rating (600 V CAT IV/1000 V CAT III), can be powered directly from the measured circuit, and has two USB ports for fast data downloads to PCs or standard thumb drives. Data logged by the 1730 can be imported into Fluke’s Energy Analyze software for further processing and archiving. Fluke also displayed its Ti200, Ti300, and Ti400 infrared cameras.

Warren Controls Inc. displayed the Monitrol, which operates differently than a pressure independent control valve (PICV) while accomplishing the same goals, more efficiently. The Monitrol uses one control element, and through its sensors it accurately knows the current flow rates. The user gets the same result of a PICV-guaranteed constant flow for a given control signal, but in the Monitrol, it is much more accurate and repeatable than in a traditional mechanical PICV. There is also the benefit of energy savings as pumps no longer have to flow against two control elements — only one.
