Product Summary

The Portable Air Flow Test Stand (PATS) is a compact air flow measurement system specially designed for highly accurate and repeatable measurement. It measures air flow for aircraft and land-based, gas turbine parts, and meets a wide range of component flow range air testing needs of OEMs and their suppliers.

Key Features

• Portability (fits in a transport case or on a work bench)


• Highly Repeatable Results (±0.25%)


• Accurate Measurement (±0.48%)


• Uses up to four automatically selected sonic nozzles


• Highly customizable controller software for test automation and data management

Related Products for Measuring Different Flow Ranges

The PATS is one in a series of air flow test stands designed for the aerospace and turbine engine-based component industries. These test stands are designed to provide complete, automated solutions for flow measurement.

Complies with OEM Test Specifications

OEMs and their suppliers worldwide require quality airflow measurement of passages in both aircraft and land-based turbine engine components. Each OEM has a unique testing specification and their suppliers must be flexible with the test procedures in order to comply with each OEM test specification. Accuracy, repeatability, throughput and availability are critical elements in the design of these test systems. These air flow test systems currently comply with the in-house testing procedures of ABB/Alstom Power, ABB Gas Turbines, Pratt & Whitney America, Pratt & Whitney Canada, General Electric Aircraft Engines (General Electric Infra, Aviation), General Electric Power Systems (General Electric Infra, Energy), Honeywell, Mitsubishi Power Systems, Mitsubishi Heavy Industries, Allison Engine, Rolls-Royce, Solar Turbines, Siemens, Siemens-Westinghouse, Snecma, and many others.

Traceable to NIST

All Flow Systems air test stand sonic nozzles and instruments are traceable to National Institute of Standards and Technology (NIST).
