The Multiple Automated Probe™ (MAP™) system measures the flow rate of a gas in transport ducts or stacks. This patented system is automated and allows for measurement with up to 4 probes simultaneously. The system brings a state-of-the-art solution to the problem of performing reliable, efficient, and accurate flow measurements according to EPA Method 1, 2, 2F, 2G, 2H.

The 3DDAS™ data acquisition system and software are tailored to perform duct and stack volumetric flow measurements according to EPA Method 2F. The heart of the 3DDAS system is a rugged, industrial computer and a 16 channel, 16-bit data acquisition board. A touch screen and wireless remote transmitter interface simplifies testing procedures. The 3DDAS uses our 3DPROBE™ program to more accurately and efficiently perform 3D duct velocity traverses. The program includes complete test configuration information, data recording and reduction report generation, and error checking. 3DPROBE is fully compliant with EPA Methods 2, 2F, 2G, and 2H. Other probe selections include the spherical probe and prism probe (also known as DAT probe).

The Non-Nulling Data Acquisition™ (NNDAQ™) system measures the flow rate of a gas in transport ducts or stacks. This system comes in automated and manual versions and allows for measurement with up to 4 probes simultaneously. The system offers the ease of EPA Method 2 and the accuracy of EPA Method 2F by using a non-nulling algorithm developed by NIST to perform reliable, efficient, and accurate flow measurements.

The Clean Air Pitot Probe is utilized to measure air velocity, pressure, and temperature within a flow stream. It uses a standard S-Type pitot probe to measure velocity and thus can follow EPA Method 2 test procedures. The probe is connected to a pressure gauge or electronic pressure transducer to measure the differential. A wind tunnel calibration is necessary in order to determine the calibration coefficient to obtain the flow velocity. An integrated thermocouple is used to measure the flow temperature. Most often, “Clean Air” testing refers to the measurement of primary air in a coal piping system when the coal flow is off. Since the Clean Air Pitot Probe meets EPA Method 2 specifications, it can also be used to measure any air or flue gas flows, including secondary air, boiler outlet, air heater inlet/outlet, electrostatic precipitator inlet/outlet, or stack exhaust.
