The ultrasonic flowmeter series includes hand-held ultrasonic flowmeter, portable ultrasonic flowmeter, fixed ultrasonic flowmeter, and fixed split ultrasonic flowmeter.
The typical application of ultrasonic flowmeters is large-diameter pipelines, where it is not convenient to install pipeline or plug-in structure instruments. Measure pure and impurity-free water.
Series ultrasonic flowmeters use low voltage, multi-pulse time difference principle, adopt precision and stable double balanced signal differential transmission, differential reception digital detection technology to measure the sound wave transmission time in the forward and reverse directions, and calculate the flow rate according to the time difference. It has the characteristics of good stability, small zero drift, high measurement accuracy, wide range ratio, and strong anti-interference.
When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a slight change in the propagation. The change in the propagation time is proportional to the flow rate of the liquid. At zero flow, the time required for the two sensors to transmit and receive sound waves is exactly the same ( The technology that can actually measure zero flow); when the medium flows, the sound wave propagation time in the countercurrent direction is greater than the sound wave propagation time in the water flow direction.
