Monitor compressed air usage and waste!
What Is The Digital Flowmeter?

EXAIR’s Digital Flow meter is an effortless way to observe compressed air consumption & waste. The exact amount of compressed air being used downstream is accurately shown on the digital display. Identifying costly leaks or inefficient air products makes it possible to save thousands of dollars per year in compressed air waste.


Why the Digital Flowmeter?

The LED display on the Digital Flowmeter directly indicates the SCFM of airflow through that pipe (other flowmeters require the reading to be multiplied by a specific conversion factor to be accurate).EXAIR’s Digital Flowmeter has two models available for use on schedule 40 iron pipe- one designed for 1”& the other for 2”.Calibration is done on each Digital Flowmeter for the specific pipe size it is mounted to.

The design of the Digital Flowmeter is made for permanent mounting to the pipe. The user is required to drill two 3/16” diameter holes through the pipe using the drill bit & locating fixture. The two flow sensing probes of the flow meter are inserted in these holes. Once the clamp is tightened the unit seals to the pipe. There is no requirement of cutting, welding, adjustments or calibration.

USB Data Logger
Monitor compressed air usage and waste!

EXAIR's new USB Data Logger Model 9147 connects directly to your Digital Flowmeter and is simple to use. Use the included 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 included software or exported directly into Microsoft Excel®. The Data Logger is available pre-installed on the Digital Flowmeter.


MODELS Digital Flowmeter with Data Logger Installed
9092-DAT 1" Pipe (Schedule 40 iron) Range: 1-80 SCFM
9092-M3-DAT 1" Pipe (Schedule 40 iron) Range: 2-136 m3/hr
9095-DAT 2" Pipe (Schedule 40 iron) Range: 2-350 SCFM
9095-M3-DAT 2" Pipe (Schedule 40 iron) Range: 3-595 m3/hr

Compressed Air Flow Meter 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) of airflow through the pipe it is mounted to. 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 40º to 120ºF (4º to 49ºC) and air pressure is between 30 to 140 PSIG. No adjustments or calibration are ever required. The Summing Remote Display is CE and RoHS compliant.

Two models of the Summing Remote Display are available:

  • Model 9150 that displays SCFM
  • Model 9150-M3 for m3/hr

It is pre-wired with 50’ (15.2m) of cable and is powered by the Digital Flowmeter. Mounting hardware is included.
