Abstract

  The article presents a method for the continuous monitoring of airflow in the ventilation system, that the department "Electrical Engineering and Automation" RGSU developed a method based on changes in the frequency and amplitude of the vibrations when the duct airflow. Designed and produced by the device based on piezo transducer prestressing. The principle of the device is based on the use of the frequency and amplitude of the vibrations of the air change rate of air flow. This method of continuous monitoring of air velocity in the duct registers change speed automatically and allows you to monitor the work of ventilation systems.
