Dwyer Instruments PAFS-1003 5-13/32" Averaging Flow Sensor

The Dwyer Instruments PAFS-1003 Averaging Flow Sensor is a differential pressure sensing component used to measure airflow in duct systems. It uses multiple sensing points along a 5-13/32" probe to capture an averaged pressure reading across the airflow stream, improving measurement consistency in variable conditions. It is applied in HVAC systems within air handling and ventilation assemblies to monitor duct airflow and support control system feedback. It is installed inside ductwork, where it converts airflow pressure differences into a usable signal for system monitoring and regulation during ventilation operation.
