In dust collection systems and in conveying of dry particulate material there is a need to maintain a specific minimum or maximum velocity to insure proper operation. Many industrial processes would benefit from a reliable velocity reading, however, monitoring actual velocity has always been somewhat of an art form rather than a technical accuracy. To meet this need, Auburn Systems designed and developed the industry’s first dry particulate velocity sensor using our patented triboelectric technology.

Most commonly, pipe line air velocity is calculated based on perceived or measured flow, actual or estimated pressure along the route, and then operated accordingly. However, when pipes or ducts are dust laden or even have small amounts of dust in the process, traditional air flow velocity sensors cannot monitor in those conditions.

Using two probes, either intrusive, or non-intrusive, we use a cross correlation technique to sense the triboelectric signature from the particulate as it passes by each of our probes. Flush-mounted ring sensor arrays provide for non-intrusive measurement and a variety of connection designs allows for easy insertion into standard pneumatic conveying lines. The result is a very accurate particle velocity.
