LN TUF-2000H TM-1 4-20 ma analog handheld portabl ultrasonic flow meter tuf2000h uses the principle of low voltage and multi-pulse time difference, and uses high-precision and ultra-stable double-balanced signal differential transmission and differential reception digital detection technology to measure the sound wave transmission time in the downstream and upstream 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 small change in the propagation time, and the change of the propagation time is proportional to the flow velocity of the liquid. When the flow rate is zero, the time required for the two sensors to transmit and receive the sound wave is exactly the same (can be The technology of actually measuring zero flow); when the medium flows, the sound wave transmission time in the countercurrent direction is longer than the sound wave transmission time in the water flow direction.
