测量原理

通过浸入过程介质的导波杆引导低功率、纳秒级微波脉冲，进

行液位物位测量。当微波脉冲抵达具有不同介电常数的介质

时，部分能量被反射回变送器。变送器利用第一次反射的余波测量界面位置。在上层产品表面未被反射的部分微波继续向下直达下层产品表面然后也被反射回来。其波速完全取决于上层产品的介电常数。发射脉冲与反射脉冲之间的时间差被换算成距离，由此计算出总体液位或界面位置。反射强度取决于被测产品的介电常数。介电常数值越高，反射强度越大。导波雷达技术的优势n 高度精确、可靠的直接液位测量，无需对变化的过程条件（如密度、导电性、粘度、 pH、温度和压力）进行补偿n 无活动部件、无需重新标定，将维护工作减到最少n 适用于蒸汽、粉尘、湍流和泡沫工况n 适用于几何形状复杂或存在干扰物的小型储罐，而且不受旁通管机械设计的影响n 由上而下的安装方式可最大程度地降低泄漏风险3301HA2S1V3BM0190JANA 5408F1SHA1I11R6AACAA4M5C1QT 3051L2AG0KD21AAM5HR53051L2AG0MA21AA5301HA1H1N3AM00200AANAM1C1Q4 5301HA1S1V5AM00800BAI1M1C1Q4QT3051L2AG0MD21AAE5M5 3301HA1S1V3AM0110AANAM1C1?5301HA1S1E3AE00206RAKA 2130DA9ES9NNNA00001NA  3051L3AC0TD21ABM5HR5 罗斯蒙特超声波液位计 3101LA1FRCG5ST2120D1BK1E5A0000 2051L3AG0XD21AAE5M5D4Q4Q8  PARent;">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A32768%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&adsid=NT&dt=1591596725201&bpp=34&bdt=326&idt=299&shv=r20200602&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Ddb34b3484dfc4c41%3AT%3D1588921024%3AS%3DALNI_MaY7lX_nxkLXJGm06pq9JGcv5RA4w&crv=1&nras=1&correlator=2458985197322&rume=1&frm=23&ife=1&pv=2&ga_vid=1108913809.1591596726&ga_sid=1591596726&ga_hid=258220134&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=50&u_java=0&u_h=900&u_w=1440&u_ah=860&u_aw=1440&u_cd=24&u_nplug=28&u_nmime=54&adx=-12245933&ady=-12245933&biw=1423&bih=706&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21060549&oid=3&pvsid=3399687426361265&pem=257&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1440%2C0%2C1440%2C860%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8220&bc=29&ifi=0&uci=0.6p5y3we7x90t&dtd=399" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.6p5y3we7x90t" data-load-complete="true">
