The company’s focus has been on energy conservation since it was founded as Conservation Devices by Roger Dennison, an energy consultant. Roger saw a need for an easily-installed flowmeter to track air usage in compressed-air systems and in 2002, the company introduced the CDI 5200 series of flowmeters.
The company now employs eleven people at its facility in Woburn, Massachusetts, and its flowmeters are used in thousands of facilities around the world. The product line has expanded to cover all pipe sizes commonly used for compressed air. Recent additions include meters for installation under pressure and meters with built-in wireless networking capability.
Recognizing the grave threat posed by climate change, the company strives to minimize energy use in its own operations and is proud to have its products playing a role in saving energy in thousands of facilities around the world.

A Few of Our Customers
The key to an effective energy conservation project is a rigorous accounting for what is being used, be it in the form of electricity, steam, natural gas or compressed air. If all usage is accounted for, no waste can go undetected. Similarly, the key to maintaining savings is ongoing monitoring: if waste develops, it will be seen and corrected. The more detailed the metering, the more rigorous the results and the greater the savings.
Roger Dennison, President of CDI Meters
It is worthwhile to learn where expensive compressed air is going, and it's not all that hard to do. Measuring compressed air flow throughout your facility allows you to identify leak loads and ineffective uses, which are problem areas you can quantify and correct."
Roger Dennison, President of CDI Meters
I wanted to personally thank you for the development and launch of such a fantastic product. These meters have provided a simple and accurate means to accurately monitor and track compressed air usage in pre-existing systems. These meters have been the key to really understanding where the air is being used across our campus as well as size new equipment to properly serve the loads.
John Kelliher, Senior Plant Engineer, Biogen Idec Inc.
We have purchased over fifty CDI flow meters & KW meters. They are very easy and convenient to use. We strategically install them in the plants and data log the information from them. Measuring air flow is the primary piece of data we are looking for. We are now compiling data and are moving in the direction of establish Best Practices for specific processes in our facilities.
Paul Lukitsch, Regional Facilities & Energy Manager, Millipore Corporation
...the facility opted to install CDI flow meters downstream of each of the flow controllers in order to monitor their real compressed air usage in SCFM daily and weekly, allowing them to understand and control their current, variable, and future compressed air needs.
Patricia Boyd, Ecos Air
CES uses flow meters on every project because they provide a direct measurement of what the compressor is supplying. The Department of Energy states that 50 percent of compressed air goes to nonproductive uses. But, by actually measuring air flow, CES has found the figure is closer to two-thirds of compressed air produced is nonproductive.
