Fluke 922/KIT Airflow Meter Micromanometer Kit measurement tool

Airflow measurement kit

The Fluke 922/KIT combines differential pressure, static pressure, air velocity and flow readings in a single rugged meter. It is designed for HVAC technicians who need to diagnose ventilation issues and balance air systems on site. The kit includes the meter and accessories for immediate field use. Compatible with most pitot tubes, it accepts user-defined duct shapes and sizes for accurate airflow calculations.

Sustained field operation

The rugged construction withstands daily transport and use in mechanical rooms, rooftops and ductwork environments. Readings remain stable during extended balancing sessions because the instrument measures pressure, velocity and flow simultaneously without switching devices. Technicians can monitor key HVAC components continuously while adjusting dampers or verifying system performance. The meter maintains its calibration through repeated pressure cycles across supply and return paths.

Pitot tube compatibility limits

Accuracy depends on selecting a pitot tube that matches the duct velocity range and inserting it to the correct traverse points. The meter itself does not compensate for poor probe placement or turbulent flow profiles upstream of the measurement plane. Users must define the duct geometry correctly in the instrument to convert velocity pressure into volumetric flow. Measurements in very low-velocity or highly branched systems may fall below the practical resolution of the pressure sensor.
