According to the Doppler effect of ultrasound, an experimental measurement system for detecting the velocity of moving bubbles in polymer solution was established. The velocity of moving bubbles in polymer solution was measured. The measurement results show that the Doppler frequency shift is proportional to the velocity of moving bubbles in the polymer solution. The ultrasonic Doppler method can be used to measure the velocity of moving bubbles in the polymer solution. It can also be used to trap small amounts of impurities in the polymer injection well Measurement of logistics volume
