In 1928, the German developed the first ultrasonic flowmeter and obtained a patent.  Ultrasonic flowmeter has a history of 75 years.


In 1955, it was first applied to Marcussen flowmeter to measure aviation combustion oil, which is a liquid flowmeter composed of two groups of probes (transducers) based on acoustic circulation method.


In 1958, a A.L.H-ERDRICH et al. invented the refractive probe. their research can further eliminate the phase distortion caused by the reverberation of the pipe wall, and also provide a theoretical basis for clamping outside the pipe.


After entering the 1970s:


Due to the development of integrated circuit and phase-locked loop technology, ultrasonic flowmeter has been able to overcome the previous fatal weaknesses of low accuracy, slow response, poor stability and reliability, so that practical ultrasonic flowmeter has been developed.


In the past 20 years, especially in the past 10 years, the rapid development of processing technology and micro-processing technology based on high-speed digital signals, research on new probe materials and technologies, research on channel configuration and flow dynamics,


Ultrasonic flow measurement technology has made great progress, showing strong technical advantages and rapid development momentum.


A total of 103 academic papers were presented at the International Conference on Flow Measurement (FLOMEK-O' 2000) held in Brazil in 2000.


Among them, there are 20 papers directly related to ultrasonic flowmeter and ultrasonic technology, accounting for about 1/5 of the total number of papers.


There are more and more documents that use ultrasonic flowmeter as the transmission standard in all previous international flow academic conferences, which shows the potential great vitality of ultrasonic flowmeter.
