3、 Working principle
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. When there is zero flow, the time required for two sensors to emit and receive sound waves is the same (a technology that can actually measure zero flow). When liquid flows, the sound wave transmission time in the upstream direction is greater than that in the downstream direction.
