Bacharach Style 2500 Air Velocity Meter Florite 0-2500 FPM HVAC Flow Meter

Bacharach Style 2500 Air Velocity Meter Florite 0-2500 FPM HVAC Flow Meter

The Bacharach Style 2500 is a Florite-type air velocity meter designed to measure airflow in ducts and ventilation systems. It reads air velocity directly on an analog scale graduated in feet per minute (FPM), with a range of 0 to 2500 FPM. Made in the USA by Bacharach, this compact, handheld instrument was built for HVAC technicians and facilities engineers who need a straightforward, portable tool for duct velocity surveys.

Applications

The Bacharach Style 2500 Florite meter is used to measure air velocity inside heating, ventilation, and air conditioning (HVAC) ductwork. Technicians insert or position the inlet in the airstream and read velocity directly off the analog scale, which can then be converted to volumetric flow rate (CFM) when the duct cross-section is known. Instruments of this type are standard tools for balancing air distribution systems, commissioning new ductwork, verifying fume hood face velocities, and troubleshooting airflow problems in commercial and industrial buildings. The Florite mechanism uses a rotating vane or thermal element to respond to airflow, giving a steady analog reading without batteries. The Style 2500's 0–2500 FPM range covers the typical velocity envelope for most supply and return air ducts. Bacharach has been a manufacturer of environmental and combustion test instruments since the early twentieth century, and instruments like the Style 2500 date from the mid-twentieth century era of analog HVAC test equipment — a period before digital anemometers became common. These instruments remain in use today in settings that rely on simple, reliable analog measurement without the need for electronic calibration.
