CDI 5250 Hot Tap Compressed Air/Nitrogen Flow Meter
The CDI 5250 allows installation under pressure. It incorporates two valves through which the probes pass and a muffler that collects chips from the drilling process. It takes an equal amount of installation time as our standard meters and requires no shutdown of the compressed-air system.
The CDI 5250 measures flow by maintaining one probe warmer than the other. It determines the mass flow rate from the amount of heat required. The flow rate, in scfm or equivalent units, is shown on a large, four-digit display; a 4-20 mA output and a pulse output permit remote display, totalizing and data collection.
The meter is designed for use with compressed air and nitrogen, and must be installed on a pressurized pipe to ensure chips are cleared. The air must be free of oil, dirt that could foul the probes, and suspended water droplets.
