Mega Flow Air Test Stand大流量空气试验台

Key Features

• Large Flow Rates (Up to 16 lbm/sec)
• Highly Repeatable Results (Less than ±0.25%)
• Measures airflow of large effective area (greater than 13 inch2 at PR = 1.05) passages in both aircraft and land-based turbine engine components (like Combustion Liners and Vane Segments)
• Small Footprint
• Dedicated Air Receiver Tank
• Uses a single, manually interchangeable sonic nozzle to measure flow
•  Highly customizable controller software for test automation and data management

How does this flow controller work?

This test stand is a sonic nozzle (critical flow Venturis) based airflow test instrument for measuring the flow parameters of flow circuits. The test station contains critical flow Venturi manifolds, piping and pneumatic control hardware, a data acquisition and switching control hardware, pressure and temperature measurement instrumentation, and a computer with control software. The computer software handles the opening and closing of critical flow Venturi flow paths and calculates airflow rates based on sensor inputs. The software also monitors the airflow conditions to ensure the sonic nozzles are in a “choked” state and that the flow is stable. The software allows for generating, saving, and recalling test configuration data as well as configuring, saving and printing test results data.
