摘　　要：超声波流量计是一种非接触式测量流量的仪表 ,它利用超声波在流体中的传播特性来测量流体的流速和流量。较其它流量计具有计量精度高、不节流、无压力损失等优点 ,特别适合天然气的在线计量、高精度贸易及其它气体的计量。Throttle style flowmeters have been used for measuring output of natural gas for many years.This style flowmeter have serious pressure attenuation disadvantage and lower precision,so it's not fit for require now.Ultrasonic wave flowmeter resolved this problem well .it have not mobile parts,and sensors can't been eroded by gas or liquid,and measurement result is not sensitive to whirlpool,and so on..So they will replace throttle style flowmeters or parts of others.This technology will represent development direction of gas measurement technology.
