关键字:FMU30 http://www.dkmeh.com/ FMU30无信号或者数据的波动厉害以及一直是在搜索,或者会显示“丢波”状态原因及其解决方案,防现场容器里面会有搅拌,液体波动比较大,会影响FMU30的测量。 FMU30无信号或者数据的波动厉害原因:超声波液位计所说的测量几米距离,指的都是指平静的水面。比如像5米量程的超声波液位计,一般就是指测量平静的水面大距离是5米,实际出厂就会做到6米。遇到容器里面有搅拌的情况下,水面不是平静的,反射信号会减弱到正常信号的一半以下。 出现这种情况的时候,我们可以用以下方法来解决: 1.所选用更大量程的FMU30,如果实际量程就是5米,那么就要用10米或者15米的超声波液位计来测量。 2.如果是不换FMU30,而且罐子里面液体无粘性,就还可以安装导波管,把超声波液位计探头防置在导波管内测量液位计高度,因为导波管内的液面基本是平稳的。 3.建议把二线制FMU30改为四线制的。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.dkmeh.com/a/news/556.htmlABSolute;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%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%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&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1605858314232&bpp=7&bdt=286&idt=30&shv=r20201112&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3D5fb7eae809183df8-22fd78660ec40024%3AT%3D1602660717%3ART%3D1602660717%3AS%3DALNI_MYMQQp2TnvCbvJQtTRQsdNX_-71Bg&nras=1&correlator=2112190514029&frm=23&ife=1&pv=1&ga_vid=1967015760.1605858314&ga_sid=1605858314&ga_hid=1602597972&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=8&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=1243&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=2&pvsid=2337431699982155&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.a9kbnwdml5hp&fsb=1&dtd=56" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.a9kbnwdml5hp" data-load-complete="true"> |
