FL-A1 type air flow meter

The FL-A1 air flow meter adopts the pitot tube principle to automatically detect air pressure at multiple points and multiple times, generating an average air flow rate (m)³/h) It has the characteristics of correctness, speed, and simplicity, and is widely used in industries such as HVAC and purification technology for direct measurement of air volume in vents and pipelines. Comprehensive management of air volume and automatic control of temperature, humidity and other parameters.

The FL type air flow meter can measure the inlet and outlet, bringing convenience to customers.

Our factory is the first in China to launch the production of this product based on advanced technology of similar foreign products. Every FL type air flow meter undergoes multi-point air flow calibration through a strict orifice plate standard wind tunnel device at the factory, providing reliable assurance for users to directly measure air flow.

FLCharacteristics and advantages of A1 airflow hood

1． Synchronize with international technology and fill the domestic gapOur air flow hood has undergone years of production and continuous improvement, and its product performance has been greatly improved and highly praised by users.

2． Guided the measurement of domestic air volume according to international standardsThe traditional measurement method is to use an anemometer to measure the data of a wind outlet multiple times to obtain a simulated air volume value, which has a large error and is cumbersome to measure. Our method uses the pitot tube principle to automatically detect wind pressure at multiple points and multiple times, generating an average air volume that is synchronized with international standards.

3． Easy and fast operationCan directly measure 70m³/h-3600m³/The air volume within the range of h is equipped with an adjustable bracket with wheels, with a total height of up to 3 meters, making air volume measurement easier; The power supply can be used for both AC and DC, and the battery can be used continuously for up to 30 hours.

4． Data statistics are more convenientIt can automatically store the air volume values of 1000 air vents, and can be viewed/deleted/printed and recorded at any time.

5． The size of the air hood can be customizedSuitable airflow hoods can be designed and made based on the size and shape of the air vents in the user's workspace, making the measurement results more accurate.

6． The product is lighter in weight and has higher strengthThe main body of our air hood is made of resin and glass fiber reinforced composite material, which effectively controls the weight (only 4KG, similar to foreign brands) and has the advantages of light material, beautiful appearance, high strength, and good toughness.

7． Higher cost-effectivenessIn terms of performance, through testing and comparison at the East China National Metrology and Testing Center, which is the only one in China that can verify the accuracy of air volume hoods, it has been proven that our accuracy is comparable to international brands (with an error of<=1% when the air volume is around 1500, and a full-scale error far below the national standard of 5%), while the price difference is two to three times.

8． Faster after-sales serviceWe provide product consultation and operation guidance throughout the working day. Fault repair, calibration, and calibration can be completed within one to three working days, fully meeting the urgent needs of customers and thinking what they want.
