Commissioning instrument meets new challenges

A commissioning device that is ideally suited to the large differential pressures associated with differential-pressure control valves (DPCVs) is Comdronic’s AC5. This instrument measures from 0 to 160 kPa and has an onboard database of over a thousand valves and flow-measurement devises. It gives commissioning engineers direct readings of flow across the entire distribution system. The AC5 is based on a powerful micro-processor that enables it to sit comfortably in the palm of a hand. All functions are accessed via just four buttons, including direct readings of differential pressure and flow, percentage of design and target flow, display of lowest and highest differential pressure and range, and selection of balancing valve from 15 worldwide manufacturers.
