The system is menu-driven from proprietary software in a portable laptop computer that prompts for all information needed for performing RATA testing using Method 1, 2, 2G, 2H and CTM-041. The Software was developed so that even the most inexperienced operator can enter data and perform testing procedures.
The patented system allows the operator to perform leak and calibration checks on the pitot assembly using the computer. The operator also uses the computer to position the pitot tube automatically at appropriate sampling points to record differential pressure, stack temperature and other data required by a specific test run.
Other specifications include:
- The Auto-Probe System typically includes four automated Method 2 probes for U.S. EPA Test Method 2 or 2G and 2H on circular stacks.
- The Auto-Probe can also be used to perform rectangular duct RATA testing using CTM-041 and up to eight probes.
- Each
measuring head contains a pitot tube and a platinum resistive
temperature device.
- 316L
SS Type S pitot tubes held to tight tolerances. Each tube is
calibrated in a U.S. EPA-certified wind tunnel at USTI offices
in Warrendale PA.
- Stepper
motors and encoders control precise positioning of pitot tubes.
- Temperature-controlled
electronic manometers (calibrated against NIST traceable pressure
source) provide exceptional accuracy and stability.
- Laptop personal computer is supplied with menu-driven software capable of performing U.S. EPA Test Methods 1, 2, 2G, 2H and CTM-041. Software is custom-programmed for test execution and data retrieval. Software prompts for geometric data and gas concentrations, then the operator uses the computer to calculate traverse point locations and stack gas molecular weight.
- Thirty differential pressure readings per second are taken at each sample traverse point.
- Static
and barometric pressure readings are measured and stored via computer.
- Data
collected and stored in the Data Acquisition System are also
stored to hard disk for future on-site reporting and for regulatory
reporting.
- Clients
are provided with both an electronic copy and a hard copy of
all services provided. For example, clients are provided with
a copy of all QA checks, a copy of all preliminary test results,
a copy of the RATA test results for each source, and an EPA
EDR formatted CD of the RATA test results (Records 610, 611,
614, 615, 616).
