Related Products for Measuring Different Flow Ranges

The Low Flow Air Test Stand 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.
