The TEC TrueFlow Grid from The Energy Conservatory is a precision airflow measurement device that uses built-in pressure sensing and Bluetooth connectivity to measure air handler flow without external pressure tubes. This innovative measurement tool connects to measureQuick for automated airflow diagnostics and system performance verification.
Non-Invasive Airflow Measurement
The TEC TrueFlow grid measures total air handler airflow by placing the device at the filter slot and using calibrated pressure sensing to calculate CFM. This approach eliminates the need for external pressure probes, pitot tubes, or duct traverses that require access to straight duct runs. The TrueFlow grid works with standard filter sizes and provides accurate airflow readings in minutes, making it practical for routine service calls rather than specialized testing scenarios.
measureQuick Airflow Integration
When connected to measureQuick via Bluetooth, the TEC TrueFlow grid streams airflow measurements directly into the diagnostic workflow. measureQuick uses the total system airflow alongside temperature and refrigerant data to calculate BTU capacity, sensible heat ratio, and system efficiency. This integration makes comprehensive system performance testing accessible to service technicians without requiring specialized airflow testing training.
System Performance Verification
Airflow measurement is critical for verifying HVAC system performance. The TEC TrueFlow grid combined with measureQuick enables technicians to quickly determine if a system is delivering design airflow, identify restricted ductwork or dirty filters, and document improvements after service. For companies pursuing ACCA Quality Installation verification, the TrueFlow grid provides the standardized airflow measurement method that these programs require for credible performance documentation.
