6 Steps to Air Savings: Step 1 – Measure!

Six Steps to Optimizing Your Compressed Air System

If you’re a follower of the EXAIR Blog, you’re probably well aware that compressed air is the most expensive utility in an industrial environment. The average cost to generate 1000 Standard Cubic Feet of compressed air is $0.25. If you’re familiar with how much air you use on a daily basis, you’ll understand just how quickly that adds up. To make matters worse, many compressed air systems waste significant amounts of compressed air just through leaks. According to the Compressed Air Challenge, a typical plant that has not been well maintained will likely have a leak rate of approximately 20%!! Good luck explaining to your finance department that you’re carelessly wasting 20% of the most expensive utility. Step 1 of the 6 steps to optimizing your compressed air system is to measure the air consumption to find sources that consume a lot of air.

In order to have an understanding of your compressed air usage across various processes and in your entire facility, you have to measure. Without a measurement of usage, there’s no way to determine your actual costs or evaluate opportunities for savings. To do so, EXAIR offers a range of Digital Flowmeters in sizes from as small as ½” Schedule 40 iron pipe and up to 4” Schedule 40 pipe from stock. Larger sizes and pipes calibrated for use on copper or metric pipe are also available.

The Digital Flowmeter provides a digital readout of the exact amount of compressed air being used. Many companies will install the DFM on each major leg of their air distribution system to allow for constant monitoring and provide a benchmark of compressed air usage.

Each meter has a built in LED display that provides the volume of air moving through the pipe in SCFM, m3/hr, or m3/min. Two small probes are inserted into holes in the pipe (drill guide kit w/ drill bit included) to detect the airflow. The unit seals to the pipe once the clamps are tightened. (If the DFM ever needs to be removed, EXAIR also offers blocking rings to seal off the holes) No cutting, welding, adjustments or calibrations are ever required.

In addition to the standard Digital Flowmeter itself, it’s also offered with wireless capability to transmit the data back to your PC, or via USB Data Logger. Both of these options will allow you to track usage over time and upload that data into an Excel spreadsheet.
