摘要
超声波燃气表作为一款智能型电子式计量仪表,若结构、电路系统等存在设计和加工缺陷,在使用过程中受到间歇性或连续性的电磁场干扰下,可能会对其计量性能造成影响,甚至无法实现正常计量工作。通过试验,研究了超声波燃气表在受到电磁场干扰的情况下,其静态及动态两种工作状态下的计量性能所受到的影响。
Ultrasonic gas meter,as an intelligent electronic metering instrument,if its structure and circuit system have design and processing defects,it may affect metering performance or even fail to achieve normal metering work under intermittent or continuous electromagnetic interference.Through experiments,this paper studies the influence of ultrasonic gas meter on its metering performance under static and dynamic working conditions when it is disturbed by electromagnetic field.
