The FL series air volume meter precisely measures the air supply volume in cleanrooms and provides accurate data on the air change rate. Air supply volume and wind speed are key indicators of the air change rate in cleanrooms. It uses the Pitot tube principle to automatically detect wind pressure at multiple points and times, automatically calculating and displaying the air volume and wind speed. The system features a touch screen for user interaction, making it easy to operate.
The FL series air volume meters can be directly used to measure the air volume at outlets and in ducts, offering quick and easy measurements. They are widely used in HVAC, purification technology, and other industries. To facilitate on-site testing for customers, a mobile bracket is provided, allowing the measurement height to reach 3.2m (including 1m of the meter body). Drawing on the advanced technology of similar foreign products, our company has pioneered the domestic production of air volume meters. Each meter undergoes multi-point air volume calibration using a strict 0.5-grade standard wind tunnel calibration device upon factory release, ensuring reliable quality assurance for users' accurate air volume measurements.
