PF Series Air Volume Bar

Measuring wing is a simple and cheap method for measuring airflow, which can be used for measuring airflow in rectangular or circular ducts. When used in conjunction with DUWEI barometers, differential pressure transmitters, electronic micromanometers, liquid column barometers and differential pressure switches, the measuring vane can accurately measure, control and record airflow velocity and volume. The measuring wing has been successfully used in various air flow measuring systems. When the measuring wing is correctly placed in the airflow, the root value of the differential pressure generated on the wing is directly proportional to the wind speed in the tube, so as to accurately measure the air flow.
