摘要
物位是工业生产自动化过程中主要测量参数之一,工况不同,物位仪表的选择也不同。如块料、颗粒状、粉料、高温、高压、粉尘、蒸汽、小介电常数等。本文详细介绍非接触超声波物位计,26GHz高频脉冲雷达物位计,导波雷达物位计的工作原理及具体选型时应考虑的工况问题,物位仪表发展趋势等。
Level is one of the main parameters in automation process of industrial production while the level meters are different for the different situation. Such as blocks, granules, powders, high temperature, high pressure, dust, steam, small dielectric constant, etc this paper describes Measuring principle and Selection should take into account the specific conditions for the non-contact Ultrasonic Level Meter, 26GHz highfrequency pulse radar level, the Guided Wave Radar level. Such as development trend of level meter is involved.
