Accu-Flow Measurement System
Accu-Flow Measurement System
The Apex Instruments Accu-Flow Measurement System is configured to use a standard S-Type pitot, a two-dimensional 3 hole prism-shaped probe or a three-dimensional 5 hole prism-shaped probe to accurately measure angular non-axial flow rates for Methods 2, 2F and 2G.
Key Features:
Since all of the sensors are mounted on the probe, accurate, stable readings can be obtained immediately. The larger ports reduce potential plugging. 1/4” pressure lines provide quicker response and are less likely to leak than standard 1/8” lines.

Description
The system provides a means for testers to improve the measurement of volumetric flow rates under cyclonic flow conditions existing in stacks and ducts. Substantial cost savings may be realized by utilizing multiple pitots, thus, minimizing the time of flow audits and also through Accu-Flow test results providing data to prevent source operation at undesirable loads.
Key Features:
- All sensors are enclosed within the Pod enclosure
- Pod is securely mounted directly to the probe extension
- Results are immediate, stable and accurate
- Larger pitot ports reduce potential plugging
- 1/4” Teflon pressure lines provide rapid response rates versus standard 1/8” lines
Key Advantages for the Source:
- Reduce operating costs
- Operate at more desirable loads
- Report lower emissions
- Save time by using automated system
Key Advantage for the Tester:
- Easy to use, rotate-to-null and record the yaw, angle, and ∆P
- Simple calibration, similar to S-Type
- Decrease test time and minimize errors
- Automated calculations and data records
- Easy-to-use, intuitive software for your laptop
Apex Accu-Flow will save time and money as well as provide more accurate certifiable results.
