Flowmeters for managing compressed air systems

December 4, 2006 introduces CAM Series compressed air flowmeters for monitoring and managing compressed air and/or nitrogen usage in industrial facilities. The new CAM Series flowmeters use thermal-dispersion mass-flow technology for localized measurement of air usage and detection of low air flows and air system leaks. The meters’ reliability and accuracy make them efficient tools for maintaining optimum air efficiency, locating leaks and controlling plant energy costs. CAM Series compressed air flowmeters from are easy to install. The meter clamps onto a vertical or horizontal pipe, with two flow-sensing probes projecting into the pipe through 3/16-inch drilled holes. The meter seals directly to the pipe without cutting or welding. Each meter is manufactured and calibrated for a specific pipe size. The meter’s digital display indicates flow directly without setup or adjustment. Meters in the CAM Series measure compressed air or nitrogen flow by maintaining one probe warmer than the other. The meter calculates the mass velocity from the amount of heat required and then calculates the flow on the basis of pipe area. The flow rate is shown in standard cubic feet per minute (scfm) on a large four-digit LED display.
