Problems solved by technology

Due to the increase in the number of sound paths, the proportional relationship between the number of sound paths and the number of ultrasonic sensors is 1:2, that is, the more the number of sound paths, the more ultrasonic sensors are arranged on the ultrasonic flow measurement equipment, and there are problems in the existing technology Yes: Due to the large number of ultrasonic sensors arranged on an ultrasonic flow measurement device, many ultrasonic sensors need to be arranged on the same pipe section body, which makes the structure of the pipe section body where the ultrasonic sensors are arranged become more and more complicated, and the processing accuracy is also higher. The production cost is getting higher and higher, and the assembly requirements for ultrasonic flow measurement equipment are getting higher and higher, and the difficulty is getting bigger and bigger; and the number of sound paths is limited by the diameter of the pipe segment, and the size of the ultrasonic sensor is different. In the case of changing conditions, if the diameter of the pipe body is small, it is unrealistic to arrange more ultrasonic sensors on the pipe body
