Description
Technical Field

The ultrasonic flowmeter is developed based on the principle that the propagation speed of ultrasonic wave in flowing medium is equal to the vector sum of the average flow speed of measured medium and the speed of sound wave in static medium, and consists of transducer and converter, and has Doppler method, speed difference method, wave beam shift method, noise method, correlation method, etc. According to the principle of signal detection, the ultrasonic flowmeter can calculate the propagation speed difference by adopting a time difference method, namely, calculate the measured fluid speed by measuring the time difference caused by different propagation speeds in forward and backward propagation. Since the sound waves traveling downstream are accelerated by the fluid and the sound waves traveling upstream are delayed, the time difference between them is proportional to the flow rate. The measurement of the flow rate may also be achieved by transmitting a sinusoidal signal to measure the phase shift between two sets of sound waves or transmitting a frequency signal to measure the frequency difference.
