EXAIR's Digital Flowmeter, with data logging capability available, is the easy way to monitor compressed air consumption and waste! The digital display shows the exact amount of compressed air being used, making it easy to identify costly leaks or inefficient air products. No cutting, welding, adjustments or calibration are ever required. It is designed for permanent or temporary mounting to a compressed air pipe. If the unit needs to be removed, blocking rings are available for most models. Available for measuring air flow in SCFM or m3/hr on 1/2" thru 8" Schedule 40 Iron Pipe, 25mm thru 101mm Aluminum Pipe and for Copper Pipe up to 4".

Accessories

USB Data Logger

EXAIR's award-winning USB Data Logger Model 9147 connects directly to the Digital Flowmeter and is simple to use. It can be configured to record flow rate from once per second to once every 12 hours. Data can be read with included software or imported into a spreadsheet.

Summing Remote Display

The Summing Remote Display allows remote viewing of Digital Flowmeter data. Additional features include: current air consumption, usage for the previous 24 hours, and total cumulative usage.

Drill Guide Kit

The Drill Guide Kit provides precise positioning to drill the holes in your pipe necessary for the probes on the Digital Flowmeter.

Block-Off Ring

The Block-Off Ring is necessary should you decide to remove or relocate your Digital Flowmeter.
