Fixed ultrasonic flowmeter

The TUF series ultrasonic flowmeter utilizes the principle of low voltage and multi pulse time difference, and adopts dual balanced signal differential transmission and differential reception digital detection technology to measure the sound wave transmission time in the forward and reverse directions, and calculate the flow velocity based on the time difference. It has the characteristics of good stability, small zero drift, high measurement accuracy, wide range ratio, and strong anti-interference ability.
When an ultrasonic beam propagates in a liquid, the flow of the liquid will cause a slight change in propagation time, which is proportional to the flow velocity of the liquid. At zero flow rate, the time required for both sensors to emit and receive sound waves is the same (the only technology that can actually measure zero flow rate); When the medium flows, the transmission time of sound waves in the reverse direction is greater than that in the water flow direction. The relationship conforms to the following expression:
