What is the USB Data Logger for Digital Flow Meters? How Can It Help Me?

USB Data Logger
The USB data logger works with all of EXAIR’s Digital Flow Meters and provides valuable feedback for optimizing your compressed air system.

EXAIR’s Model 9147 USB Data Logger has become one of the most valuable tools that we sell to help customers get a “view” of their compressed air usage over time. One of the important tenets we promote at EXAIR is energy savings by prudent use of compressed air through our engineered solutions (Air Knife, Air Nozzles, Air Amplifier, etc.). But how does a person in charge of such systems really “know” whether they are helping or hurting their compressed air system?

The first step is to have an appropriate flow meter which can give an indication of how much air volume is being used. EXAIR’s line of Digital Flow Meters are perfect for getting to that point with instant and direct readings that don’t need to be calculated any further. What you see on the meter is the flow in either SCFM or m3/hr calibrations.

The second step is to attach the USB Data Logger to the Digital Flow Meter so that readings can be kept over time. It is like setting up a security camera for your compressed air system. Nothing gets by without being recorded.

The USB Data Logger can be connected to just about any type of monitoring system that has a 4 – 20 mA output to which the 2-wire harness can be installed. A quick and easy initialization to choose the unit of measure, to select the frequency of measurement and some optional alarms is all that is necessary. The software package is included with the USB Data Logger and is convenient to run on a typical desktop or laptop computer. You simply, set it and forget it (at least until you want to do some reporting).

The reporting is how the USB Data Logger can help you as the person concerned with monitoring the compressed air use in your facility. Once the defined monitoring period of time has passed, the USB Data Logger can be removed from its socket, stopped from recording and the data is then downloaded into a suitable format that can be imported into EXCEL or other spreadsheet program for creating charts to analyze what is happening, when it is happening and how much compressed air is being used. In the analysis, you can compare the flow data and times with certain problems in a production line that might cause low pressure condition which shuts machinery down. You might also be able to determine where additional, point of use compressed air storage might be needed close to certain processes.

Ultimately, the USB Data Logger allows you to “see” your compressed air system in a way that allows you to sleuth out problems seen that might have no other explanation. It can also help you to justify your air savings when you apply the other air saving compressed air products that EXAIR produces by monitoring a base line for “before” performance and “after” performance. After all, it if is important to your organization, it should be measured. And compressed air is certainly a utility that should be measured.
