Portable Ultrasonic Flowmeter uses the principle of low voltage, multi-pulse time difference, the use of high-precision and ultra-stable double balance signal differential transmission, differential reception digital detection technology, when the ultrasonic beam propagates in the liquid, the flow of the liquid will make a small change in the propagation time, 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 only technology that can actually measure zero flow), and when the liquid flows, the transmission time of sound waves in the countercurrent direction is greater than that in the forward direction.
