Flow Management Devices LLC, was established in the state of Arizona in 2007. In 2008 we applied for our first patent on “Next Generation” of small volume Provers (SVP) or Unidirectional Captive Displacement Provers (CDP).  Unidirectional Captive Displacement Provers are designed to calibrate or prove a liquid flow meter’s accuracy and repeatability under actual operating conditions in the field or calibration laboratories. In January of 2010 we were granted our first patent in innovative design of the Prover. Since inception we have applied for 4 patents, some are still pending.

Our management and engineering team has over 60 years of experience in design and manufacturing of industrial equipment including the design and manufacture of the first SVP. 

We are a service oriented engineering company with manufacturing capabilities. We have created a customer oriented team with a “can do” attitude willing to accept measurement challenges in the Oil and Gas industry.
