Potential industrial applications in which these sensors may be used include air-to-fuel ratio calculations, analytical instrumentation, fuel cells, non-corrosive gas leak detection, non-corrosive gas meters, HVAC filters, and the VAV system on HVAC systems. This list includes several traditional applications as well as some new industrial applications where airflow sensors may be used. Honeywell’s Airflow Sensors have been frequently used in HVAC applications; however, there are new and emerging potential applications such as fuel cells in which the new Zephyr™ Airflow Sensor may be used.
