Gas Flow Measurement System based on Ultrasonic TOF
摘要
As one of the four major parameters in industrial process measurement, flow has always been an important topic in the field of automatic detection, and its measurement is of great significance in industrial production and process control. At present, the gas flowmeters applied in China's industrialization mainly include turbine flowmeters, hole plate flowmeters, vortex flowmeters, etc., which all belong to the traditional flowmeters.. However, with the continuous improvement of market demand and the rapid development of science and technology, the defects of such traditional flowmeters are more and more obvious. In contrast, the measurement accuracy of the ultrasonic flowmeter is almost unaffected by the temperature, pressure and even density of the liquid under test., and the generalization of this new flowmeter is crucial.
