HVAC Code Tester – Airflow Meter

Precise airflow supply and measurement to a variety of test pieces.  Also used for automotive cabin leak testing, developing fan performance, flow versus pressure curves.  Can be coupled with an Air Supply System for conditioned temperature and humidity. Geometry built according to ASHRAE 41.2.  Ability to apply/perform back pressure control to simulate product pressure drop.

Features

  • Multiple nozzle arrays to achieve high turn down ratios, manually or automatically actuated
  • Variable speed blower to control based on airflow or pressure
  • Rugged CRS construction assures minimal body leakage and long term dependability
  • Data collection and computation through PLC based touch screen, also available through LabVIEW® automation software packages
  • Used as a stand alone system or integrated with other Q Corporation supporting modules, including coolant or refrigerant supply systems
