Abstract

Abstract: Fluid plays an important role in engineering application and the accurate control of the carrier is the premise of energy efficient conversion and management, such as the primary air volume of the boiler, the reactor inlet flowrate, the amount of oil and air intake of internal combustion engine, etc. Therefore, flowmeter plays an important role in energy conversion and management. In this work, a high-low frequency combined with reflection-penetration synchronization flowmeter was designed to measure the flowrate in casing device based on the characteristics of different frequencies of sound. The flowrate calculation method of casing device is given and verified by numerical simulation. The results show that the flowrate of different flow states can be calculated accurately by using the high-low frequency combined with reflection-penetration synchronization method. At the same time, the method can also be used in electromagnetic wave, optical and other fields.
