The AG-TFP07 ultrasonic flowmeter utilizes the transit time difference method to calculate gas flow velocity by measuring the difference in sound wave propagation time. The system consists of one ultrasonic sensor and one signal processor. The transit time difference is directly related to the axial average velocity of the gas, enabling precise gas velocity calculations.
