DUC uses the acceleration and deceleration effects of sound signals propagating in flowing liquids for measurement, and establishes a sound transmission path through two sensors clamped outside the pipeline. The sensor sends and receives sound signals, which are then converted into time t1 and t2 by the transmitter. The signals from sensor A to B are accelerated by the fluid (shorter t1), while the feedback signals from sensor B to A are slowed down by the fluid (longer t2). The difference between t1 and t2 and the length of the sound transmission path L can be used to calculate the average flow velocity of the fluid. This principle is called the ultrasonic propagation time difference principle, and the flow rate can be calculated by converting the geometric data and flow velocity of the pipeline.

DUC emits signals into the interior of the pipeline, and the reflected signals received will be used for comparison with the emitted signals. Only when the reflected signal is correlated with the emitted signal, will this set of signals be used for flow calculation (based on signal evaluation of interaction correlation). The flow calculation is completed by an integrated DSP (digital signal processor), so the calculation has a sampling frequency of * *.

DSP calculates the propagation time of sound waves by measuring the digital signal of sound wave propagation time, which is very accurate, drift free, and does not require maintenance or secondary calibration. Ultrasonic transducers are installed on pipelines to send and receive ultrasonic signals used in flow transmitters to calculate volumetric flow rates. Red shell,

Flow measurement is applicable to one or two different measurement points with two ultrasonic transducers.
