雷达物位计合理选择装置地位十分重要

雷达物位计能否正确测量，依赖于反射波的信号，假如在所选择装置的地位液面不能将电磁波反射回雷达天线零碎或在信号波的范围内有搅扰物反射搅扰波给雷达物位计，雷达物位计就不能正确反映实践液位，因而合理选择装置地位对雷达物位计非常重要。

1.雷达物位计天线的轴线应与液位的反映外表垂直，不可装置于罐顶的中心地位，否则会发生多重虚伪回波，搅扰回拨会招致信号丧失。

2.雷达物位计尽量远离进料和排放口。由于液位在注入时会发生幅度比被测液体反射的无效回波大得多的虚伪回波。同时旋涡惹起的不规则液位会对微波信号发生散射，从而惹起的不规则液位会对微波信号发生散射，从而惹起有无效信号的衰减，所以应避开它们。3.雷达物位计尽量远离搅拌、挡板等有能够搅扰的地位。由于关于搅拌器等容器搅拌时会发生不规则的旋涡，会形成雷达信号的衰减。同时搅拌器的叶片也会对微波信号形成虚伪的回波，特别是被测物体的介电常数较小和低液位时，搅拌器所形成的影响更为严重。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=908ABSolute;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?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%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=32.0.0&pra=5&wgl=1&dt=1600847814728&bpp=12&bdt=311&idt=45&shv=r20200918&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&nras=1&correlator=3625372345256&frm=23&ife=1&pv=1&ga_vid=1014614971.1600847815&ga_sid=1600847815&ga_hid=622942019&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=6&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=1286&bih=626&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530672&oid=3&pvsid=3836928306228982&pem=16&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&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=0&uci=0.gnly4vn16mc9&fsb=1&dtd=83" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.gnly4vn16mc9" data-load-complete="true">
