USTI's AUTO-PROBE Q2000® system reduces or eliminates the over-reporting of volumetric flow rates. As a result, over-reporting of emissions is eliminated or significantly reduced.

Bottom line: More accurate reporting of actual emissions saves money...

  • in emissions allowances that do not have to be purchased;
  • in allowances that do not have to be used to offset over-reported emissions; and
  • in capital expenditures that might not have to be made for pollution control systems.

USTI’s technology is considered essential to maintain a cost-effective generating fleet, especially as emission allowances become more valuable. USTI allows you to refine the calibration of a unit's continuous emissions monitoring system (CEMS), in turn reducing the cost of meeting compliance obligations.

Manual RATA testing of CEMS equipment tends to overstate flue gas velocity, according to John Mc Manus, AEP vice president of environmental services. "The result is overstated emissions."

The AUTO-PROBE Q2000® automatically and accurately performs stack and duct flow testing procedures with a high degree of repeatability -- saving time and money.

"In the two years that AEP used USTI, prior to acquiring the company, we realized millions of dollars in savings because we were more accurately reporting our emissions," Mc Manus said. "AEP acquired USTI when it was offered for sale because we wanted to see this technology and service stay on the market, available for use by any company required to monitor its emissions. It's the most accurate reference test method available on the market."

Other ways you benefit:

  • The automated process eliminates human error. The pitot tubes are precisely positioned at the proper sampling location by the computer and all data collected during testing is performed using the computer -- no manual operations during the test, no manual data entry.
  • Saves time compared with manual audit methods. The audit process for U.S. EPA Test Method 2 takes about one and ½ hours for 12 runs (48 points per run), meaning less time to operate units at non-normal loads. Manual testing can take up to four hours or more for a 16-point test at a given load.
  • Accuracy is assured through automation and tightly-held tolerances. Automated U.S. EPA Test Method 2H for wall effects correction. Automated U.S. EPA Test Method 2G for yaw correction. Automated pre- and post-leak and calibration checks. Modified pitot design reduces error due to pitch. On-site production of reports, including EDR's (Electronic Data Reports). No transcription of data required.
  • Automated audit procedure is repeatable to a high degree of accuracy because settings are stored on hard disk. Custom software drives automated procedure, assuring repeatable process that is accurate to +/- 1.0%.
