摘要
文章介绍了国外超声物位计的发展和应用现状 ,主要有以下几个方面 :(1)超声换能器品种的多样化 ,以满足不同应用对象。在设计和应用时要考虑换能器的频率、功率、温度、方向性和灵敏度等因素 ;(2 )仪表智能化参数设定和适应性实现了智能化 ,不仅扩大了应用范围 ,而且保证了测量的可靠性和精确度 ;(3)主要应用范围和存在的问题 ;(4)
Recent development and application of some kinds of ultrasonic level detector from abroad were introduced in this paper. There are four facets as follow. (1) The diversification of ultrasonic transducer,that is for meeting different demand. The frequency,power,temperature,bearing and sensitivity should be put into consideration for user and designer.(2) Instrument intellectualized in parameter setting and adaptability.(3) Main application range and existing problems.(4) Future development.
