Product Summary
The Mini Flow Air Test Stand is an air flow measurement system specially designed for highly accurate and repeatable measurement at low flow ranges. It measures air flow for large 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
- Small Footprint for use in Cellular Manufacturing
- Highly repeatable results (±0.25%)
- Accurate measurement (±0.48%)
- 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.
