What are ultrasonic flow sensors?

Ultrasonic flow sensor is a sensor that uses ultrasonic technology to measure liquid or gas flow in a non-contact manner. It mainly 

consists of two main components: transmitter and receiver. The transmitter sends an ultrasonic signal into the fluid, which travels 

through the fluid and reaches the receiver. The receiver receives the ultrasonic signal reflected back after passing through the fluid 

and converts it into an electrical signal for processing.

According to the principle of signal detection, ultrasonic flow sensors can be roughly divided into propagation velocity difference 

methods (including direct time difference method, time difference method, phase difference method, frequency difference method), 

beam offset method, Doppler method, correlation method, and spatial filtering. Method and noise method and other types. Among 

them, the frequency difference method and the time difference method overcome the error caused by the change of sound speed 

with the fluid temperature and have high accuracy, so they are widely used.

In addition, according to the configuration method of the transducer, the propagation velocity difference dial is divided into Z method 

(transmission method), V method (reflection method), X method (cross method), etc.

Ultrasonic flow sensors have many advantages, such as non-contact measurement, high measurement accuracy, easy installation and 

maintenance, etc., so they have been widely used in many fields, such as industrial automation, environmental monitoring, water 

treatment, etc.
