Digital Flowmeter

Digital Flowmeter™


Monitor compressed air usage and waste!

Intelligent Compressed Air Product


What Is The Digital Flowmeter?

EXAIR's new 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 downstream. This makes it possible to save thousands of dollars per year in compressed air waste – helping to identify costly leaks or inefficient air products. Many companies install the Digital Flowmeter on each major leg of their air distribution system to constantly monitor and reduce compressed air usage.

Why the Digital Flowmeter?

The Digital Flowmeter has an LED display that directly indicates the SCFM of airflow through that pipe (other flow meters require the reading to be multiplied by a specific conversion factor to be accurate). Two models are available for use on Schedule 40 iron pipe – one designed for 1" Schedule 40 iron pipe and the other for 2". Each Digital Flowmeter is calibrated for the specific pipe size it is mounted to.

The Digital Flowmeter is designed for permanent mounting to the pipe. It requires the user to drill two 3/16" diameter 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.

Digital Flowmeter

USB Data Logger

EXAIR's USB Data Logger (Model 9147) connects directly to your DAT model Digital Flowmeter and is simple to use. Download the most up to date software from www.easylogusb.com 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 downloaded 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) 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.
