Digital Flowmeter™

Monitor compressed air use and waste!

EXAIR’s Digital Flowmeter family is available in many sizes.

What Is The Digital Flowmeter?

EXAIR’s Digital Flowmeter 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 insufficient air products. Many companies install the Digital Flowmeter on each major leg of their air distribution system to constantly monitor and benchmark compressed air usage.

The Digital Flowmeter has an LED display that directly indicates the SCFM or m3/hr volume of airflow through that pipe. Each Digital Flowmeter is calibrated for the specific pipe size to which it is mounted. Models are available for measuring air flow in SCFM on Schedule 40 Iron pipe from ½” to 6” diameter. Airflow meters for Copper pipe up to 4” and Aluminium pipe up to 101mm are also available.

The Digital Flowmeter is designed for permanent or temporary mounting to the pipe. It requires the user to drill two small holes through the pipe using the included drill bit and locating fixture. The two flow sensing probes of the flowmeter are inserted in these holes. The unit seals to the pipe once the two clamps are tightened. No cutting, welding, adjustments or calibration are ever required. If the unit needs to be removed, blocking rings are available. NEMA Type 4 (IP66) meters are available. Please contact us.

USB Data Logger

EXAIR’s award-winning Model 9147 USB Data Logger connects directly to your Digital Flowmeter and is simple to use. Download the software to configure the Data Logger to record your flow rate from once a second (about nine hours of data) up to once every 12 hours (over 2 years!).
When the Data Logger is removed from the Digital Flowmeter and plugged into a computer, the data can be viewed in the software or exported directly into Microsoft Excel. The Data Logger is available pre-installed on the Digital Flowmeter.

Summing Remote Display

EXAIR’s Summing Remote Display for the Digital Flowmeter makes it easy to monitor compressed air consumption from a convenient location. With the push of a button, the display cycles to show the current air consumption, usage for the previous 24 hours, and total cumulative usage. Regular monitoring of the air usage of a machine, process or department makes it possible to save thousands of dollars per year in compressed air waste by identifying the costly leaks or inefficient air products.

The Digital Flowmeter (sold separately) has a four-digit LED display that directly indicates the SCFM (standard cubic feet per minute) or m3/hr (cubic metres per hour) of airflow through the pipe it is mounted upon. The Summing Remote Display shows that flow measurement, the daily and cumulative usage and is frequently used when the Digital Flowmeter is in an obscure, hard to read location. The accuracy of the displayed measurement is within 5% of the reading when the air temperature is 4ºC to 49ºC (40ºF to 120ºF) and air pressure is between 2 to 10 BAR (30 to 140 PSIG). No adjustments or calibration are ever required.

The Summing Remote Display is prewired with 15.2m (50-foot) of cable and is powered by the Digital Flowmeter.
