The ultrasonic flowmeter uses the low-voltage, multi-pulse time difference principle, and adopts high-precision and ultra-stable dual-balance signal differential transmission and differential reception digital detection technology to measure the transmission time of sound waves in the downstream and upstream directions, and calculates the flow velocity according to the time difference. It features good stability, small zero drift, high measurement accuracy, a wide range ratio, and strong anti-interference capability.
 When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a slight change in the propagation time, and the change in propagation time is proportional to the flow velocity of the liquid. At zero flow, the time required for the two sensors to transmit and receive sound waves is exactly the same (the only technology that can actually measure zero flow); when the medium flows, the sound wave transmission time in the upstream direction is greater than the sound wave transmission time in the water flow direction.
