About Us

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 eight people at its facility in Woburn, Massachusetts, and has sold 40,000+ flowmeters to over 70 countries. Industries include:

  • Textile
  • Automotive
  • Food & Beverage
  • Semiconductors
  • Pharmaceutical
  • Plastics Molding
  • Bioremediation
  • Foundries

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 facilities around the world.
