雷达液位计负压下出现显示波动如何解决

雷达液位计在负压状态下可能发生液位显示波动现象，可按以下步骤进行分析和解决。

首先查看液位计磁翻板的显示情况，如果磁翻板显示稳定，就是液位变送单元或信号传输部分出现了问题，继续测量液位变送器输出的电流信号、控制柜内配电隔离器的输出电流信号及线路是否正常，从而查出故障点。然后，如果液位计磁翻板显示情况和上位显示波动一致，波动不剧烈时，首先关闭雷达液位计与测量容器的连接阀门，打开排污阀排污，同时继续检查液位计浮球本身是否有问题，如没问题，就检查雷达液位计上、下丝堵及排污阀和连接法兰处是否出现泄漏，同时通过改变液位计上、下阀门的开度观察液位计的波动情况。通过这些措施可确定液位计的好坏。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 地址：武汉市武昌区中南国际城D座一单元901室 原文出处：http://www.dkmcn.com/News_show.asp?id=815ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-pointer-lock 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%2C8%3A32776%2C9%3A32776%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&dt=1588840011382&bpp=2&bdt=219&idt=168&shv=r20200505&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8%3AT%3D1588147156%3AS%3DALNI_MZhOWs11HQ-EEy1X6tCtUAbNrQ6cw&crv=1&nras=1&correlator=7697399795684&frm=23&ife=1&pv=1&ga_vid=1042389293.1588840012&ga_sid=1588840012&ga_hid=1595936051&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=16&u_nmime=33&adx=-12245933&ady=-12245933&biw=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21065532%2C21066085&oid=3&pvsid=632282485182711&pem=851&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fflag%3D12&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=8220&bc=31&ifi=0&uci=0.2y3q88n8tqwv&fsb=1&dtd=189" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.2y3q88n8tqwv" data-load-complete="true">
