关键字:雷达液位计 http://www.dkmcn.com/ 导波雷达液位计是一种新型的液位测量仪表,在外观上,导波雷达液位计显著的地方是其配备有金属导波杆。 当导波雷达液位计发射的雷达波沿导波杆传播到气相介质和待测液体介质的分界面处时,由于在分界面处上下介质的介电常数值相差极大,根据时域反射原理,一部分雷达波能量会在该处发生反射。反射的雷达波会被液位计接收,通过对回波信号进行分析,获得发射雷达波与返回雷达波的时间差,即可根据时间差与光速相乘,计算待测的液位高度。 通过导波雷达液位计的原理可以发现,其测量原理完全独立于密度。并且由于雷达波是在导波杆内传播,蒸汽、粉尘、泡沫等工况对雷达波传播的衰减程度影响很小。因此面对高温高压、一般蒸汽的工况时,导波雷达液位不需要对温度和压力进行补偿,可以直接用于液位测量。并且由于导波雷达液位计的导波杆部分没有活动部件,因此也具有维护成本低、可靠性高的优点,适用于多种复杂的工况。SANs-serif" style="overflow-wrap: break-word;">德科蒙过程控制(武汉)有限公司座机:027-88062221传真:027-88068180邮箱: sales@whdkm.com原文出处:http://www.dkmcn.com/News_show.asp?id=1000ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?guci=2.2.0.0.2.2.0.0&client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C9%3A32776%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0&pra=5&wgl=1&dt=1613807896709&bpp=13&bdt=651&idt=101&shv=r20210211&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=6010386790563&frm=23&ife=1&pv=2&ga_vid=161714417.1613807897&ga_sid=1613807897&ga_hid=772976466&ga_fc=0&nhd=1&u_tz=480&u_his=4&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=17&u_nmime=34&adx=-12245933&ady=-12245933&biw=1332&bih=649&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44736624%2C21068496%2C21068769%2C21068893&oid=3&pvsid=347198867265814&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=1&uci=1.srgrz5h40xch&fsb=1&dtd=225" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.srgrz5h40xch" data-load-complete="true"> |
