Overview

For small and medium-sized air ducts, due to the influence of the regulating door, if the air flow device can only be installed in front and behind, there will be many problems in measuring the air volume. To solve this measurement problem, the FCY-110E plug-in section air velocity tube flow device is a specially designed air volume measurement product based on this situation. As shown in the figure below, it is arranged with enough measuring points in the pipeline, completely solving the problem of uneven flow field caused by the regulating door. Using this device, the output differential pressure has good tracking with the regulating door, which can truly reflect the changes in air volume and meet the requirements of automatic regulation and protection of the system.
